A Co-based superalloy, Co-9Al-9W (at%), was processed by mechanical alloying by high-energy milling of elemental powders and consolidated by field assisted hot pressing (FAHP). The milled powder particles mainly consist of undissolved bcc-W as well as WC and an Al and W rich fcc-γ Co solid solution. After consolidation and heat treatment a fine grained microstructure with a high fraction of carbides and a γ/γ′ microstructure was obtained. The compressive yield strength at room temperature was found to be 45% higher than that of previously reported results for Co-based superalloys. A similar level of strength was found at 700 °C. These extraordinary properties can be explained due to the multitude of hardening mechanisms that sintered Co-based superalloys possess: γ′ precipitation, carbide formation and the ultra-fine γ-grain size promoted by the fast consolidation technique.

钴基高温合金Co-9Al-9W（at％）通过元素粉末的高能铣削进行机械合金化处理，并通过现场辅助热压（FAHP）进行固结。研磨后的粉末颗粒主要由未​​溶解的bcc-W和WC以及富含Al和W的fcc-γCo固溶体组成。经过固结和热处理后，获得了具有高碳化物含量和γ/γ'微观结构的细晶粒组织。发现在室温下的抗压屈服强度比先前报道的基于Co的高温合金的抗压屈服强度高45％。在700°C时发现了类似的强度。这些非凡的性能可以通过烧结Co基高温合金具有的多种硬化机制来解释：γ'沉淀，
