用粉末冶金方法可将金属及其合金粉末生产出特殊的管、棒或类似的形材。方法是先将金属及其合金粉末制成薄壁的包套,将其进行冷等静压,随后进行热加工及特殊的热挤压。 在进行冷等静压以前,将氮气和氢气的混合气体导入包套。金属粉末的预压可用振荡或类似的方 The powder metallurgy method can produce special tubes, rods or similar shapes for metals and their alloy powders. The method is to first make the metal and its alloy powder into a thin-walled sheath, subject it to cold isostatic pressing followed by hot working and special hot extrusion. Before cold isostatic pressing, a mixed gas of nitrogen and hydrogen is introduced into the jacket. The metal powder can be pre-pressed oscillating or the like
