GB/T 14999.2-2012 Test methods for superalloys—Part 2:Verification of transverse macro-structures and defect by etch
Abstract
This part of GB/T 14999 specifies the types and characteristics of common defects and uneven structures in the transverse low-magnification microstructure of high-temperature alloys, as well as the methods of sample cutting and preparation, sample etching, inspection and evaluation, result presentation methods, and inspection reports.
This part is applicable to the transverse low-magnification microstructure inspection of high-temperature alloy cast ingots, melt-tested materials, and forged (rolled) billets or parts. Other products can be implemented in accordance with this standard.
