  1. Tial - based alloys with high specific strength are the most potential high temperature structural materials for aerospace application. however, the application of these materials is hindered by low resistance of damage, low room - temperature ductility and fracture toughness and high crack growth rate

    Tial基合金比強度高，是最具潛力的航空、航天用高溫結構材料之一，但因其具有較低的抗損傷能力，較低的室溫塑性、斷裂韌性和高裂紋擴展速率，這些斷裂特性阻礙了這種材料的應用，因而仍有必要研究其斷裂機理。
  2. Fatigue experiments were performed to obtain the fatigue lifetime under the different loading. the parameters for law of the fatigue crack growth were obtained by crack growth experiments. in order to study the fatigue characteristics at high temperature, creep tests were also done

    本文對多種典型焊接試件開展了諸多的試驗研究工作：進行單軸靜載拉伸試驗以確定構件的強度；進行疲勞壽命試驗以測得疲勞壽命曲線；進行疲勞裂紋擴展試驗以獲得試件的疲勞裂紋擴展規律paris公式；進行蠕變試驗以考察焊接試件疲勞持久特性；進行剩餘壽命試驗以獲得試件的剩餘壽命。
  3. ( 1 ) the data of fatigue crack growth rates at high temperature for four materials are gained. the laws of fatigue crack growth with temperature are researched

    （ 1 ）首次獲得了四種材料較為完整的高溫疲勞裂紋擴展數據，探索了這些材料隨溫度變化的疲勞裂紋擴展規律。
  4. The result of research enriches the trial method, get the fatigue crack growth laws of four kinds of pressure vessel materials at high temperature. provide a kind of numeric method

    本文的研究結果，豐富了試驗方法;得到四種壓力容器材料的高溫疲勞裂紋擴展規律;對疲勞裂紋擴展路徑判定提供一種計算機方法。
  5. ( 3 ) both oxide - induced closure and embrittlement of grain boundaries take place for 2 - cr1mo and 2 - cr1mov at high temperature. the change of fatigue crack growth rates with temperature is not so evident as 316land 16mnr

    裂紋表面氧化引進的閉合效應和晶界脆化相對比較均衡，裂紋擴展速率隨著溫度升高的變化沒有鐵素體和奧氏體材料明顯。
  6. Therefore, the study on fatigue crack growth laws at high temperature is very useful for safety of high temperature equipments

    因此，高溫下疲勞裂紋擴展規律的研究具有很大的工程實用價值。
