- 性 : Ⅰ名詞1 （性格） nature; character; disposition 2 （性能; 性質） property; quality 3 （性別） sex ...
- 退 : 動詞1 （向後移動） retreat; draw back; move back 2 （使向後移動） cause to move back; remove; wit...
- 火 : fire
- 韌性 : 1. （指頑強持久的精神） tenacity 2. [力學] toughness; ductility; ductibility
- 退火 : [冶金學] anneal; annealing; back-out
-
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。Milling, turning, planning of cast iron, annealed cast iron, steel, austenitic steel. medium cutting speed and chip cross - sections. for interrupted cutting and varying cutting depths. high toughness and impact strength
對鑄鐵、退火鑄鐵、鋼鐵、奧氏體鐵進行銑削、車削、刨平加工的牌號。適合中等切削速度、中等切削截面的切削加工。適合不同切削深度和間斷性切割。抗沖擊強度高、韌性高。In order to accomplish the main targets, the following jobs were done : the annealing of ct20 alloy tube at 6 different temperatures was carried out and the specimens with different microstructure were tested at room temperature ( rt ) and 20k. the tensile fractures were analyzed by means of sem and tem. the c t20a alloy specimens with 3 kind of oxygen equivalent ( oeq ) were prepared, and the tensile properties at rt and 20k, the impact toughness at rt and 77k were tested
為了研究顯微組織和間隙元素含量變化對兩種合金低溫塑韌性的影響，研究中主要作了如下工作：對ct20合金管材進行了六種溫度的退火處理，測試了不同組織試樣的室溫和20k拉伸性能，對拉伸試樣取樣進行sem和tem分析；制備出了ct20a合金三種氧當量實驗樣品，測試了相應試樣的室溫和20k拉伸性能以及室溫和77k沖擊性能，並取樣進行sem和tem分析；在以上工作的基礎上，對近鈦合金的低溫塑韌性機理進行了探討。
