martenite

基本解釋

It also has more martenite, so the hardness of the HAZ can reach HRC51 which is the highest in the joint.
(2) 焊接工藝參數(shù)（焊接熱輸入、焊接電流、焊接速度）對新型鑄造熱作模具鋼焊態(tài)焊接接頭的組織及硬度影響較大。
The results show that the structure of steel consists of lath martenite and lower bainite.
在一個(gè)奧氏體晶粒內(nèi)一般存在四個(gè)板條領(lǐng)域，裂紋尖端的塑性區(qū)內(nèi)存在主位錯(cuò)帶。
The crack initiates at stress concentration point in the root of weld, where has much more martenite, carbide and inclusion, and the serious hydrogen segregation.
裂紋均在焊縫根部應(yīng)力集中處萌生，該處馬氏體含量比較大，碳化物及夾雜物較多，氫的偏聚現(xiàn)象嚴(yán)重。
