    用单试样法或多试样法,研究了错合金在室温和400的循环变形。
  • Zircaloy - 4 is generally used as fuel tubes in pressurized water reactors because of it " s low neutron absorption cross - section , excellent corrosion resistance , good strength and ductility
    由于锆4合金具有低的中子吸收截面,良好的抗腐蚀能力、高强度以及延展性好的特点,被广泛用于压水堆作为核燃料棒的包壳材料。
  • Low cycle fatigue ( lcf ) behavior of zircaloy - 4 has been reviewed in the present paper . then , the lcf behavior of a recrystallized zircaloy - 4 plate with different texture has been studied at room temperature and 400 , respectively
    并在此基础上,研究了不同温度(室温和400 ) 、不同取向(平行于轧向和垂直于轧向)的再结晶退火态zr - 4合金板材试样的低周疲劳性能。
  • 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
    对于冷加工后经再结晶退火处理的zr - 4合金,轧制方向的低周疲劳寿命比横向要大。随着_ p的降低,两个方向的低周疲劳寿命的差别相应增加,这是由于合金中存在织构的缘故。冷加工后经再结晶退火处理的zr - 4合金在固溶处理后,抗疲劳性能明显降低,这主要是由于固溶处理降低了合金的schmid因子;固溶处理后在相区的退火对疲劳性能有影响,即500 1 . 5h退火的抗疲劳性能要优于750 1 . 5h退火,这主要与500 1 . 5h退火的合金中沉淀相粒子的数量较少有关。
  • 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,合金表现出与常温下不同的循环特性,其循环稳定滞后回线出现锯齿状波形,且在整个疲劳过摘要程中呈现出一致循环硬化的现象,这主要是因为合金在400下发生动态应变时效效应的结果。
  • While cyclic deformation experiment under constant strain control is performed in 400 , the material shows the continuous hardening until cyclic invalidation . ( 3 ) back stress attained by kwl " s method is used to analyse the bauschinger effect during an incremental step cyclic test and cyclic deformation test under constant strain control , it is shown that back stress increases with increasing plastic strain and the numbers of cycle , and the back stress is uniform , regardless of tension or compression conditions . ( 4 ) as far as recrystallized zircaloy - 4 plate is concerned , the back stress in transverse direction is higher than that in rolling direction due to the higher schmid factor in rolling direction
    对于再结晶状态的zr一4合金板材试样来说, t方向(横向)试样的背应力要高于r方向(轧制方向)的背应力,原因在于r方向的schmid因子高于t方向的schmid因子; 400下, zr一4合金的背应力要明显低于室温下的背应力;含氢200pg / g的zr一4合金的背应力大小与无渗氢的zr一4合金背应力相比,无明显区别;固溶处理后, zr一4合金的背应力大小发生了变化,在较高塑性应变下,背应力均高于固溶处理前的背应力。
  • So it is very important to understand the cyclic deformation behavior of zircaloy - 4 . in this paper , bauschinger effect of zircaloy - 4 with different metallurgical state at room temperature and 400 ? is investigated in an incremental step test and cyclic deformation test under constant strain control . bauschinger effect during cyclic deformation is described by using back stress , which is mainly responsible for bauschinger effect ; back stress is attained by using kwl " s method
    本文采用单试样逐级加载循环变形和恒应变幅循环变形试验,研究了不同冶金状态、温度、氢以及固溶处理下的zr - 4合金的bauschinger效应现象;种种结果表明,影响bauschinger效应的主要因素是背应力;本文正是从背应力的角度来分析各种状态下zr - 4合金的bauschinger效应现象;背应力的计算主要通过使用kwl方法而获得。
