ASTM A262-2010 探测奥氏体不锈钢晶间腐蚀敏感度的标准实施规程
简介:1.1 These practices cover the following five tests: 1.1.1 Practice A8212;Oxalic Acid Etch Test for Classification of Etch Structures of Austenitic Stainless Steels (Sections 3 to 7, inclusive), 1.1.2 Practice B8212;Ferric Sulfatex2013;Sulfuric Acid Test for Detecting Susceptibility to Intergranular Attack in Austenitic Stainless Steels (Sections 8 to 14, inclusive), 1.1.3 Practice C8212;Nitric Acid Test for Detecting Susceptibility to Intergranular Attack in Austenitic Stainless Steels (Sections 15 to 21, inclusive), 1.1.4 Practice E8212;Copperx2013;Copper Sulfatex2013;Sulfuric Acid Test for Detecting Susceptibility to Intergranular Attack in Austenitic Stainless Steels (Sections 22 to 31, inclusive), and 1.1.5 Practice F8212;Copperx2013;Copper Sulfatex2013;50 % Sulfuric Acid Test for Detecting Susceptibility to Intergranular Attack in Molybdenum-Bearing Austenitic Stainless Steels (Sections 32 to 38, inclusive). 1.2 The following factors govern the application of these practices: 1.2.1 Susceptibility to intergranular attack associated with the precipitation of chromium carbides is readily detected in all six tests. 1.2.2 Sigma phase in wrought chromium-nickel-molybdenum steels, which may or may not be visible in the microstructure, can result in high corrosion rates only in nitric acid. 1.2.3 Sigma phase in titanium or columbium stabilized alloys and cast molybdenum-bearing stainless alloys, which may or may not be visible in the microstructure, can result in high corrosion rates in both the nitric acid and ferric sulfate-sulfuric acid solutions. 1.3 The oxalic acid etch test is a rapid method of identifying, by simple etching, those specimens of certain stainless steel grades that are essentially free of susceptibility to intergranular attack associated with chromium carbide precipitates. These specimens will have low corrosion rates in certain corrosion tests and therefore can be eliminated (screened) from testing as x201C;acceptable.x201D; 1.4 The ferric sulfatex2013;sulfuric acid test, the copperx2013;copper sulfatex2013;50 % sulfuric acid test, and the nitric acid test are based on weight loss determinations and, thus, provide a quantitative measure of the relative performance of specimens evaluated. In contrast, the copperx2013;copper sulfatex2013;16 % sulfuric acid test is based on visual examination of bend specimens and, therefore, classifies the specimens only as acceptable or nonacceptable. 1.5 In most cases either the 15-h copperx2013;copper sulfatex2013;16 % sulfuric acid test or the 120-h ferric sulfatex2013;sulfuric acid test, combined with the oxalic acid etch test, will provide the required information in the shortest time. All stainless grades listed in the accompanying table may be evaluated in these combinations of screening and corrosion tests, except those specimens of molybdenum-bearing grades (for example 316, 316L, 317, and 317L), whi......

GB/T 36174-2018 金属和合金的腐蚀 固溶热处理铝合金的耐晶间腐蚀性的测定
简介:本标准规定了没有保护层的固溶热处理铝合金耐晶间腐蚀性的测试方法。固溶热处理铝合金对晶间腐蚀的敏感性是随合金的化学成分、生产方法、固溶热处理、淬火处理和沉淀硬化(时效)处理过程变化的函数。在自然时效条件下,固溶热处理铝合金晶间腐蚀的敏感性主要是临界温度范围内淬火过程中冷却速率的函数。本标准适用于铸件、锻件、厚板、薄板、型材和半成品或成品零件的铸造和锻造热处理铝合金。适用于基于不同化学成分及其他因素对不同牌号和厚度的合金进行等级评估及材料热处理质量的检测。测试结果给出了确定材料耐晶间腐蚀和热处理质量的信息。该测试结果不是绝对的,因为它们并不适用于所有的服役环境。这些测试结果更适用于比较不同热处理温度下,固溶热处理铝合金的耐晶间腐蚀性。

ASTM G67-2004 用接触硝酸环境之后的重量损失来测定5XXX系列铝合金晶间腐蚀敏感性的标准试验方法(NAMLT 试验)
简介:This test method provides a quantitative measure of the susceptibility to intergranular corrosion of Al-Mg and Al-Mg-Mn alloys. The nitric acid dissolves a second phase, an aluminum-magnesium intermetallic compound (x03B2;Al-Mg), in preference to the solid solution of magnesium in the aluminum matrix. When this compound is precipitated in a relatively continuous network along grain boundaries, the effect of the preferential attack is to corrode around the grains, causing them to fall away from the specimens. Such dropping out of the grains causes relatively large mass losses of the order of 25 to 75 mg/cm2 (160 to 480 mg/in2), whereas, samples of intergranular-resistant materials lose only about 1 to 15 mg/cm2 (10 to 100 mg/in2). When the x03B2;Al-Mg compound is randomly distributed, the preferential attack can result in intermediate mass losses. Metallographic examination is required in such cases to establish whether or not the loss in mass is the result of intergranular attack. The precipitation of the second phase in the grain boundaries also gives rise to intergranular corrosion when the material is exposed to chloride-containing natural environments, such as seacoast atmospheres or sea water. The extent to which the alloy will be susceptible to intergranular corrosion depends upon the degree of precipitate continuity in the grain boundaries. Visible manifestations of the attack may be in various forms such as pitting, exfoliation, or stress-corrosion cracking, depending upon the morphology of the grain structure and the presence of sustained tensile stress.3 1.1 This test method describes a procedure for constant immersion intergranular corrosion testing of 5XXX series aluminum alloys.1.2 This test method is applicable only to wrought products.1.3 This test method covers type of specimen, specimen preparation, test environment, and method of exposure.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

These specimens will have low corrosion rates in certain corrosion tests and therefore can be eliminated (screened) from testing as "acceptable." 1.4 The ferric sulfate-sulfuric acid test, the copper-copper sulfate-50% sulfuric acid test, and the nitric acid test are based on weight loss determinations and, thus, provide a quantitative measure of the relative performance of specimens evaluated. In contrast, the copper-copper sulfate-16% sulfuric acid test is based on visual examination of bend specimens and, therefore, classifies the specimens only as acceptable or non-acceptable. 1.5 In most cases either the 24-h copper-copper sulfate-16% sulfuric acid test or the 120-h ferric sulfate-sulfuric acid test, combined with the oxalic acid etch test, will provide the required information in the shortest time. All stainless grades listed in the accompanying table may be evaluated in these combinations of screening and corrosion tests, except those specimens of molybdenum-bearing grades (for example 316, 316L, 317, and 317L), which represent steel intended for use in nitric acid environments. 1.6 The 240-h nitric acid test must be applied to stabilized and molybdenum-bearing grades intended for service in nitric acid and to all stainless steel grades which might be subject to end grain corrosion in nitric acid service. 1.7 Only those stainless steel grades are listed in Table 1 for which data on the application of the oxalic acid etch test and on their performance in various quantitative evaluation tests are available. 1.8 Extensive test results on various types of stainless steels evaluated by these practices have been published in Ref (1). 1.9 The values stated in SI units are to be regarded as standard. The inch-pound equivalents are in parentheses and may be approximate. 1.10 This standard does not purport to address all of the safety problems, if any, associated with its use.

ASTM G67-2013 用接触硝酸环境之后的重量损失来测定5XXX系列铝合金晶间腐蚀敏感性的标准试验方法 (NAMLT试验)
简介: 4.1x00a0;This test method provides a quantitative measure of the susceptibility to intergranular corrosion of Al-Mg and Al-Mg-Mn alloys. The nitric acid dissolves a second phase, an aluminum-magnesium intermetallic compound (x03b2;Al-Mg), in preference to the solid solution of magnesium in the aluminum matrix. When this compound is precipitated in a relatively continuous network along grain boundaries, the effect of the preferential attack is to corrode around the grains, causing them to fall away from the specimens. Such dropping out of the grains causes relatively large mass losses of the order of 25 to 75 mg/cm2 (160 to 480 mg/in2), whereas, samples of intergranular-resistant materials lose only about 1 to 15 mg/cm2 (10 to 100 mg/in2). When the x03b2;Al-Mg compound is randomly distributed, the preferential attack can result in intermediate mass losses. Metallographic examination is required in such cases to establish whether or not the loss in mass is the result of intergranular attack. 4.2x00a0;The precipitation of the second phase in the grain boundaries also gives rise to intergranular corrosion when the material is exposed to chloride-containing natural environments, such as seacoast atmospheres or sea water. The extent to which the alloy will be susceptible to intergranular corrosion depends upon the degree of precipitate continuity in the grain boundaries. Visible manifestations of the attack may be in various forms such as pitting, exfoliation, or stress-corrosion cracking, depending upon the morphology of the grain structure and the presence of sustained tensile stress.3 1.1x00a0;This test method describes a procedure for constant immersion intergranular corrosion testing of 5XXX series aluminum alloys. 1.2x00a0;This test method is applicable only to wrought products. 1.3x00a0;This test method covers type of specimen, specimen preparation, test environment, and method of exposure. 1.4x00a0;The values stated in SI units are to be regarded as the standard.
