Molybdenum powder of 3 μm is pressed into a blank of 30 mm thickness by holding pressure at 250 MPa for 60 s. The molybdenum sheet is sintered in hydrogen at 1900 °C for 4 h to obtain a molybdenum plate. Then the billet is opened at 1400 ℃ and the molybdenum plate is hot rolled from 30 mm to 19 mm, and then the molybdenum plate is rolled to 2 mm or 1 mm by two or three passes. mechanical properties collection scheme: five bone samples are cut from each plate along the rolling direction, perpendicular rolling direction, and the angle of 45° with the rolling direction for stretching, and finally the average value is taken; two parallel samples are taken from each plate, and the surface of the samples is Mechanical grinding and polishing were carried out, and hardness tests were performed on a HVS-1000 Vickers hardness tester with a load of 0.3 kg and a holding time of 15 s. Five hardness measurements were performed on each sample, and the average value was determined. Microstructure acquisition scheme: The samples were first mechanically ground and polished on the surface, then etched in a mixture of 53 % potassium ferricyanide and 49 % sodium hydroxide for 60 s. The microstructure was observed with a leica DMIL LED microscope. Weaving acquisition protocol: Weaving measurements were performed on the surface and in the center of the mechanically polished prepared plates. The Bruker X-ray weave stress meter (D8 Discover) was used for the determination of the polar maps, which measured the crystallographic surfaces of (110), (200) and (211), and then the corresponding ODF maps were analyzed using the relevant software to characterize the surface weave and the central weave of the samples.
