纯钼板制品可以通过粉末冶金方法制备烧结坯料,再通过轧制变形得到期望的尺寸和性能。轧制工艺对钼板的性能有非常重要的作用,通过比较分析3 种交叉轧制与单向轧制钼板的性能和微观组织的差异发现,交叉轧制可以显著改善各向异性,使材料具有优良的综合性能。随着温度的提高,轧制工艺对于钼板性能的影响明显减弱,晶粒再结晶和长大使钼板的高温性能基本一致。
Pure molybdenum plate products can be prepared by powder metallurgy method sintered billet, and then through rolling deformation to obtain the desired size and performance. The rolling process has a very important effect on the performance of the molybdenum sheet. By comparing and analyzing the performance and microstructure of the three types of cross-rolled and unidirectionally rolled molybdenum sheets, it is found that the cross-rolling can significantly improve the anisotropy and make the material Has excellent comprehensive performance. As the temperature increases, the influence of the rolling process on the properties of the molybdenum sheet is significantly weakened, and the grain recrystallization is basically the same as the high-temperature performance of the long-term molybdenum sheet.
