Frame hardening and tempering of iron and steel parts
钢铁件的火焰淬火回火处理

Induction hardening and tempering of iron and steel parts
钢铁件的感应淬火回火处理

Process of induction hardening and tempering of iron and steel
钢铁的感应淬火和回火处理

Ansforging and tempering of steel
钢的锻造余热淬火回火处理

Process of carburizing and carbonitriding , quenching and tempering of iron and steel
钢铁的碳化氰化淬火和回火处理

Standard specification for pressure vessel plates , alloy steel , 9 percent nickel , double - normalized and tempered
压力容器用经二次正火及回火处理的含9镍的合金钢板标准规范

Annealing could reduce hardness and raise toughness , which could be prone to mechanical machining . quenching and low temperature tempering could raise intensity and hardness of materials , not reduce toughness obviously . quenching on same temperature caused ticp / fe in situ composites having the best integral machine properties
退火处理使材料的硬度降低,韧性提高,便于机械加工;淬火+低温回火处理使材料的强度和硬度提高,而韧性无明显的降低;采用等温淬火工艺,可使tic _ p fe复合材料具有最好的综合机械性能。

The principle of multi - method and multi - parameter is suggested , which should be followed during characterizing microstructures of alloy steels by ultrasonic not method . ultrasonic velocity ( c , ) of transformation products through different heat processes of three steels was measured by high - accuracy ultrasonic installation . the velocity of quenched microstructure of 38crmoal is the lowest , which gradually increases with increasing tempering temperature between 200 ? and 650 ? after quenching process
利用ti - 40n高精度超声波测厚仪,研究了超声波在不同钢种、不同热处理转变产物中的超声波速度c _ 1 : 38crmoal钢淬火组织c _ 1最小,淬火后在200 650范围内进行回火处理时,随回火温度的升高, c _ 1逐渐升高, hrc与c _ 1之间具有较好的相关性;正火组织的c _ 1介于淬火后中温回火及高温回火产物组织的c _ 1之间。
