美国精细材料技术公司(MMT)生产了一种平均粒子尺寸为15μm的超细球形粉末,在这以前<50μm的粒子没有生产出来。超细TiAl粉末适于注塑、等离子熔炼后,用来生产出高密度的构件。 MMT的专利工艺是:将原料等离子熔化,同时将熔滴超细雾化后生产出快速凝固超细粉末。该工艺没有副产品,球形粒子分布均匀可增加粉末的封装密度和粉末的流动陡。由于粉末是快速凝固获 American Fine Material Technology (MMT) produced an ultra-fine spherical powder with an average particle size of 15 μm, to which particles <50 μm were not produced before. Ultrafine TiAl powder for injection molding, plasma melting, used to produce high-density components. MMT’s patented process is: melting the raw material plasma, while ultrafine droplets atomized to produce rapidly solidified ultra-fine powder. The process has no by-products, and the uniform distribution of spherical particles increases the packing density of the powder and the flow of the powder steeply. As the powder is rapidly solidified
