  1. 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

    對于再結晶狀態的zr一4合金板材試樣來說, t方向(橫向)試樣的背應力要高於r方向(軋制方向)的背應力,原因在於r方向的schmid因子高於t方向的schmid因子; 400下, zr一4合金的背應力要明顯低於室溫下的背應力;含氫200pg / g的zr一4合金的背應力大小與無滲氫的zr一4合金背應力相比,無明顯區別;固溶處理后, zr一4合金的背應力大小發生了變化,在較高塑性應變下,背應力均高於固溶處理前的背應力。
  2. 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

    本文採用單試樣逐級加載循環變形和恆應變幅循環變形試驗,研究了不同冶金狀態、溫度、氫以及固溶處理下的zr - 4合金的bauschinger效應現象;種種結果表明,影響bauschinger效應的主要因素是背應力;本文正是從背應力的角度來分析各種狀態下zr - 4合金的bauschinger效應現象;背應力的計算主要通過使用kwl方法而獲得。
