quenched and tempered steel

基本解釋

Effect of Ti-containing complex inclusions on the microstructure and mechanical properties of medium carbon non-quenched and tempered steel;
用金相顯微鏡、掃描電鏡和能譜觀察和分析了轉(zhuǎn)爐生產(chǎn)的含硫非調(diào)質(zhì)鋼軋后硫化物夾雜的形貌。
The evaluation of measuring uncertainty in metallic material Brinell hardness test is studied by testing the hardness of the 45 quenched and tempered steel.
以45#調(diào)質(zhì)鋼硬度試驗(yàn)為例，研究了金屬材料布氏硬度試驗(yàn)中測量不確定度的評定。
The thermal fatigue crack propagated mainly through the break-age of the interface of carbide and grain boundaries for either quenched or quenched and tempered steel.
無論是淬火或淬回火態(tài)的試樣其熱疲勞裂紋主要沿著碳化物與基體脫開處及晶界裂紋橋接而擴(kuò)展。

調(diào)質(zhì)鋼
Using the 20Mn2SiVB steel to substitute for the quenched and tempered steel to make the automobile roof beam, and adopting the treatments of 1250℃forging and then air-cooling, one can obtain the following relative contents of the phases in the microstructure: 9% remnant austenite plus 6% ferrite, and the others are bainite and a small amount of martensite （or tempered martensite）. If so, the manufacturing and application requirements of the automobile roof beam can be satisfied.
綜合分析結(jié)果,利用20Mn2SiVB鋼代替調(diào)質(zhì)鋼制造汽車前梁,始鍛溫度1250℃,鍛后空冷,當(dāng)復(fù)相組織中各相的相對含量為:9%殘余奧氏體+6%鐵素體,其余為貝氏體和少量馬氏體（或?yàn)榛鼗瘃R氏體）時(shí),能夠滿足汽車前梁的生產(chǎn)制造和使用要求。
