low temperature tempering meaning in English
低温回火
Examples
- The variation principle of wave velocity in different microstructures of 40cr is similar with that of 38crmoal . the velocity in quenching and low temperature tempering structure of gcrlssimn is much lower than the velocity in normalizing , annealing and high temperature tempering structure
Gcr15simn钢淬火+低温回火组织的c _ 1远大于正火、退火及淬火+高温回火组织的c _ 1 ；正火、退火及淬火+高温回火组织的c _ 1比较接近。 - 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。 - Results of the experiments showed that the wear mechanisms of the sintered steel included abrasive wear , adhesive wear and fatigue wear , and it was the abrasive wear most important . it was the sintered steel mixed by ni , mo that was the best on the wear resistance , because of the great lot of bainite ; the sintered steel quenched and low temperature tempered mixed by mo , w that was the best on the wear resistance , because of the rigidity of the steel was the highest
实验结果表明：本文中几种烧结钢的磨损机制均是由磨粒磨损、粘着磨损、和疲劳磨损共同作用的，且以磨粒磨损为主；在烧结态下，复合添加合金元素镍、钼的烧结钢的耐磨性能最好，这是因为生成了大量的硬质相贝氏体；而淬火、低温回火态下，则复合添加钼、钨的烧结钢的耐磨性能最好，这是因为热处理态下添加钼、钨的烧结钢的硬度最高。
