tempered martensite

基本解释

X-Ray analysis finds that steel after tempering main matrix of tempered martensite.
用X-射线衍射分析发现，试验钢回火后的组织主要为回火马氏体。
The final structure obtained from tempering a fully hardened steel is called tempered martensite.
回火完全淬硬钢得到的最终组织结构被称为回火马氏体。
The strength of the steel was highest when aging at 470℃. The tempered martensite embrittlement appeared at 450℃ i. e. , the impact toughness was the lowesies.
时抗拉强度达最高值，在450℃附近时效出现回火脆性，冲击韧性处于低谷。
