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。 -
