brittlement

基本解釋

The large coarsened martensite and grainy bainite are the internal causes of brittlement.
粗大的馬氏體和焊接過程產(chǎn)生的粒狀貝氏體是脆化的內(nèi)在原因.
With more accidents taking place in such gas fields, researchers start to think much of the role of CO2 during hydrogen brittlement.
隨著在這類氣田中油套管斷裂事故頻繁發(fā)生，CO2在氫脆腐蝕發(fā)展中的作用開始引起了人們的重視。
It is concluded that hydrogen brittlement of the disloation-tooth circletproduced during zinc coating is the reason of fracture failure.
通過金相顯微鏡觀察、掃描電鏡分析、能譜分析和含氫量的測定,得出錯齒墊圈斷裂失效是由于在鍍鋅過程中產(chǎn)生氫脆的結(jié)論。
The results show that the failure is mainly attributed to the inappropriate heat-treatment technology of the locking nut and the hydrogen brittlement from electroplating of the stopping pad.
由此得到：構(gòu)件失效的主要原因是：鎖緊螺母的熱處理工藝不當，止動墊電鍍過程發(fā)生氫脆。
