tempering hardness 中文意思是什麼
tempering hardness
解釋
回火硬度-
Moreover, laser overlapping treatment is another actual problem in many places. by a lot of experiments, as be showed in many theses, we find the hardness of mould steels were lowered because of tempering
並且，激光交疊熱處理是在生產中可能發生的問題，我們通過大量的實驗發現在激光硬化區由於一定程度的回火效應而產生硬度回落現象。 -
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
退火處理使材料的硬度降低，韌性提高，便於機械加工；淬火+低溫回火處理使材料的強度和硬度提高，而韌性無明顯的降低；採用等溫淬火工藝，可使tic _ p fe復合材料具有最好的綜合機械性能。 -
Quenching and tempering were chosen to strengthen the material. the quenching temperature and time were adjusted based on the hardness measurement
選擇淬火和回火作為本課題的熱處理工藝，並用硬度法確定可行的淬火溫度和保溫時間。 -
Using the device, we tested two groups of samples that included the steel of 40cr and the steel of 65mn, got a single - valued relationship between displayed value on the device and tempering hardness
對以40cr和65mn為代表的回火件進行了硬度測試，得到了其回火硬度與數顯值之間良好的單值對應關系。
