reduced hardness meaning in Chinese
折合硬度
Examples
- Diamonds for industrial cutting tools can be grown faster , because inclusions do not reduce hardness
因为杂质并不会影响钻石的硬度，所以工业上用来做切割的钻石，合成的时间可以较短。 - 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。
