以过渡金属与类金属为基的微晶合金,因其独特的超细组织而具有优异的性能。在这类材料的设计上,类金属含量的确定是一个关键。为了实现液态急冷→非晶态→反玻璃化→微晶态→粉末冶金法固结→形成块状材料的工艺路线,必须有足够高的类金属含量,以获得非晶淬火态;另一方面,为了要使最后所得到的块状材料具有足够高的韧性,以满足工程材料的要求,又必须限制类金属含量,以免形成过多的硬而脆的间隙化合物相。B系合金是这类材料中的主要部 Transition metal and metalloid-based micro-alloy, because of its unique ultra-fine structure and has excellent performance. In the design of such materials, the determination of metal content is a key. In order to achieve liquid quenching → amorphous → de-vitrification → microcrystal → powder metallurgy consolidation → process of forming bulk materials, there must be a sufficiently high metalloid content to obtain an amorphous quenched state; on the other hand , In order to make the resulting bulk material has high enough toughness to meet the requirements of engineering materials, but also must limit the metal content, so as not to form too hard and brittle gap compound phase. B series alloy is the main part of this type of material
