This Standard applies to deformed superalloys, cast superalloys (isometric crystal cast superalloys, directionally solidified columnar crystal superalloys, and single crystal superalloys), superalloy wire for welding, powder metallurgy superalloys, dispersion strengthened superalloys and high temperature intermetallic materials.2 Classification2.1 Superalloy classification According to the basic forming method or special use of alloys, alloys are classified into deformed superalloys, cast superalloys (isometric crystal cast superalloys, 2.2 Classification of high temperature intermetallic materials According to the basic constituent elements of the high temperature materials, the high temperature materials are classified into nickel-aluminum-based high temperature intermetallic materials and titanium-aluminum-based high temperature intermetallic materials. 3 Naming rules and use of designation for superalloys and high temperature intermetallic materials 3.1 For superalloys and high temperature intermetallic materials which have been scientifically researched, trial-produced, 3.2 Superalloys and high temperature intermetallic materials in the scientific research and trial-production stage can be named according to the designation representation method of this Standard. 3.4 The designations of superalloys and high temperature intermetallic materials are represented by a combination of letters and Arabic numerals.4 Representation method of designation4.1 Designation prefix The designation of deformed superalloy is prefixed with the Chinese phonetic alphabet “GH” (“G” and “H” are the first letters of Chinese Pinyin “Gao” and “He”, respectively); 4.2 Arabic numerals 4.2.1 Deformed superalloy and superalloy wire for welding 4.2.2 Other superalloys and high temperature intermetallic materials 4.2.2.1 The prefix of cast superalloy is generally followed by three Arabic numerals. The first digit indicates the alloy’s classification code.5 Designations of superalloys and high temperature intermetallic materials and their chemical composition5.1 The chemical composition of the alloy or material designations listed in this Standard is a general chemical composition. 5.2 Designations of deformed superalloys and their chemical composition are shown in Table 1. 5.3 Designations of cast superalloys (isometric crystal cast superalloys, directionally solidified columnar crystal superalloys, and single crystal superalloys) and their chemical composition are shown in Table 2. 5.7 Designations of high temperature intermetallic materials and their chemical composition are shown in Table 6. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
