tempered martensite

基本解釋

X-Ray analysis finds that steel after tempering main matrix of tempered martensite.
用X-射線衍射分析發(fā)現(xiàn)，試驗鋼回火后的組織主要為回火馬氏體。
The final structure obtained from tempering a fully hardened steel is called tempered martensite.
回火完全淬硬鋼得到的最終組織結(jié)構(gòu)被稱為回火馬氏體。
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.
時抗拉強度達最高值，在450℃附近時效出現(xiàn)回火脆性，沖擊韌性處于低谷。
