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。
