zircaloy 中文意思是什麼

zircaloy 解釋
n. 名詞 鋯合金〈具有耐熱、耐腐蝕等特性，常在原子反應堆中用以分隔燃料和冷卻劑〉。

  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。

  8. 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。
  9. 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。
