钢渗碳淬火回火金相检验标准探讨

Discussion on Metallographic Examination Standards for Carburizing,Quenching and Tempering Steel

对国内主要行业渗碳淬火回火金相标准的检测指标、显微组织级别的划分和评定列表进行了对比,结合国外标准,分析、探讨了该类标准的适用性、实用性等问题,并就这些标准的贯彻实施提出了一些设想。

Test targets, classification and evaluation of microstructure levels in standards for carburizing, quenching and tempering of steel in the major trades at home were contrasted in tabulated data. Combined with related stan- dards abroad, the suitability and practicability of the above standards were discussed. In addition, some idieas about the implementation of standards were given as well.
