摘要： A powder metal steel alloy composition for high wear and temperature applications is made by water atomizing a molten steel alloy composition containing C in an amount of at least 3.0 wt %; at least one carbide-forming alloy element selected from the group consisting of: Cr, V, Mo or W; an O content less than about 0.5 wt %, and the balance comprising essentially Fe apart from incidental impurities. The high carbon content reduces the solubility of oxygen in the melt and thus lowers the oxygen content to a level below which would cause the carbide-forming element(s) to oxidixe during water atomization. The alloy elements are thus not tied up as oxides and are available to rapidly and readily form carbides in a subsequent sintering stage. The carbon, present in excess, is also available for diffusing into one or more other admixed powders that may be added to the prealloyed powder during sintering to control microstructure and properties of the final part.

摘要翻译： 用于高耐磨和高温应用的粉末金属钢合金组合物通过水溶雾化含有至少3.0重量％的C的钢水合金组合物来制备; 至少一种选自Cr，V，Mo或W的碳化物形成合金元素; O含量小于约0.5重量％，除了偶然的杂质外，余量基本上包含Fe。 高碳含量降低了氧在熔体中的溶解度，从而将氧含量降低至低于这一水平的水平下会使碳化物形成元素氧化的水平。 因此，合金元素不会被氧化并且可以在随后的烧结阶段快速且容易地形成碳化物。 过量存在的碳还可用于扩散到一种或多种其它混合的粉末中，其可以在烧结期间添加到预合金粉末中以控制最终部件的微结构和性质。
