高碳铬轴承钢退火缺陷组织及评级

摘要

在充分理解和领会标准评定原则的基础上,结合实际工作经验,对因原材料、热处理工艺及生产设备等因素造成的退火缺陷组织的检验及评级问题进行了深入的探讨,并对长期以来极容易引起争议的退火缺陷组织的识别及级别评定提出了建议.%Based on understanding standard grading rules, incorporating with practical experience, the inspect and grading is discussed deeply for defective annealing microstructure resulting from raw material, heat treatment process and equipment, and the recommendation is suggested for recognition and grading of the debatable microstructure.
