roll direction meaning in English
滚转方向
压延方向
Examples
- Iron and steel . profiled plates in rolling direction
钢铁.沿轧制方向成型的钢板 - Click on the rolling direction of the arrow adjustments , in order to keep the ball to the opposite wall
点击滚动的箭头调整方向，要想办法把球踢到墙的对面。 - And strengthening contribution of t1 phase is maximal in the rolling direction , minimal in the transverse direction , and midterm in the 45 direction , which means that contribution of t1 phase to anisotropy of alloys is contrary to that of textures
相在纵向和横向的强化贡献最大，而在45方向的强化贡献最小，即与织构的作用一致； t _ 1相的强化贡献则在纵向最小，在横向最大，在45方向较大，即与织构的作用相反。 - 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。 - 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。
