Similarly, PM Mo powders and TM Mo powders were first made into Mo plate blanks with thickness of 22 mm by cold isostatic pressing and sintering. Then, by the plate mill, two kinds of Mo plate blanks were rolled to the Mo sheets with thickness of 0.5 mm thickness and 0.2 mm thickness, respectively. The rolling method of 0.5 mm thickness Mo sheets was unidirectional rolling and 0.2 mm thickness Mo sheets was cross rolling from that. In the article, the 0.5 mm thickness and 0.2 mm thickness Mo sheets that prepared with PM Mo powder were marked as PM5 and PM2, and, the 0.5 mm thickness and 0.2 mm thickness Mo sheets that prepared with TM Mo powder were marked as TM5 and TM2.
