  1. Zircaloy - 4 sheet, which was cold - worked followed by recrystallization annealing, exhibits longer lcf life in the rolling direction than that in the transverse direction, and the fact that difference in lcf life between both directions becomes larger as the range of plastic strain becomes lower can be attributed to the texture effect, p - solution treatment deteriorates the alloy ' s lcf property because the treatment lowers the average value of alloy ' s schmid factors, and the subsequent annealing - treatment in a - phase range has a impact on the lcf properties, i. e. the subsequent annealing - treatment at 500 ? for 1. 5h results in better property than that at 750 for 1. 5h, which comes mainly from the fact that the alloy annealled at 500 for 1. 5h has lower amount of the precipitate particles than the alloy annealled at 750 for 1. 5h

    對于冷加工后經再結晶退火處理的zr - 4合金，軋制方向的低周疲勞壽命比橫向要大。隨著_ p的降低，兩個方向的低周疲勞壽命的差別相應增加，這是由於合金中存在織構的緣故。冷加工后經再結晶退火處理的zr - 4合金在固溶處理后，抗疲勞性能明顯降低，這主要是由於固溶處理降低了合金的schmid因子；固溶處理后在相區的退火對疲勞性能有影響，即500 1 . 5h退火的抗疲勞性能要優於750 1 . 5h退火，這主要與500 1 . 5h退火的合金中沉澱相粒子的數量較少有關。

  4. The lcf behavior of a recrystallized zircaloy - 4 plate at room temperature and 400 show that alloy has better lcf property at rt than at 400, and cyclic hardening at 400 which could be attributed to the dynamic strain aging effects. it is noticeable that the hydrided plate has the same cyclic behavior as the above unhydrided sample at room temperature

    在400下，合金錶現出與常溫下不同的循環特性，其循環穩定滯后回線出現鋸齒狀波形，且在整個疲勞過摘要程中呈現出一致循環硬化的現象，這主要是因為合金在400下發生動態應變時效效應的結果。
  5. In this dissertation, the effect of texture, heat - treatment, and hydrogen on the lcf behavior of zircaloy - 4 and the cyclic deformation behavior for zircaloy - 4, n18 alloy and n36 alloy have been investigated systematically using fully - reversed tension - compression loading under strain control ( r = min / max = - 1 ), while the evolvement of the friction and back stresses versus the number of repeated working cycles and the plastic strain amplitude has been studied, and the thorough discussion combined with the analysis result of fatigue sub - structure, friction and back stresses, and fatigue fracture has been given to the mechanism underlying the lcf behavior of alloys

  6. However, the lcf of r specimen containing - 200 g / g hydrogen is better than that of the hydrided t specimen, and shows slightly superior to unhydrided r specimen, whereas the hydrided t specimen has not the apparent difference as compared with t specimen

    與室溫下未滲氫態試樣相比，滲氫后r向試樣的低周疲勞性能稍稍優于未滲氫態r向試樣，但對t向zr一4合金試樣，滲氫對其室溫低周疲勞性能幾乎沒有影響。
