quenched and tempered steel

基本解释

Effect of Ti-containing complex inclusions on the microstructure and mechanical properties of medium carbon non-quenched and tempered steel;
用金相显微镜、扫描电镜和能谱观察和分析了转炉生产的含硫非调质钢轧后硫化物夹杂的形貌。
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#调质钢硬度试验为例，研究了金属材料布氏硬度试验中测量不确定度的评定。
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.
无论是淬火或淬回火态的试样其热疲劳裂纹主要沿着碳化物与基体脱开处及晶界裂纹桥接而扩展。

调质钢
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.
综合分析结果,利用20Mn2SiVB钢代替调质钢制造汽车前梁,始锻温度1250℃,锻后空冷,当复相组织中各相的相对含量为:9%残余奥氏体+6%铁素体,其余为贝氏体和少量马氏体（或为回火马氏体）时,能够满足汽车前梁的生产制造和使用要求。
