铁、铝和碳化钨粉末的元素粉末作为机械合金化的起始材料，混合得到所需的Fe-40at%Al+ 50,65vol %WC。粉末混合物使用行星球磨机研磨360公里。采用真空1373 K脉冲电流烧结工艺对粉末进行了固结。由此得到的致密物由FeAl和WC组成。FeAl-WC的维氏硬度与先前研究中使用Fe-40at%Al粉和WC粉制备的试样基本相同。然而，本研究制备的FeAl-WC的横向断裂强度不如后一种工艺。这是由于不同工艺制备的FeAl-WC的微观结构不同。
Elemental powders of iron, aluminum and tungsten carbide powders has been used as starting materials for mechanical alloying and mixed to give the desired composition of Fe-40at%Al+50, 65vol%WC. The powder mixtures were milled for 360 ks using a planetary ball mill. Milled powders have been consolidated using pulse current sintering process at 1373 K in vacuum. The compacts thus obtained consisted of FeAl and WC. The FeAl-WC has had almost the same vickers hardness as the specimen prepared using milled Fe-40at%Al powder and WC powder in the previous study. However, the transverse rupture strength of FeAl-WC prepared in this study was inferior to the latter process. This is due to the different microstructure of FeAl-WC prepared by the different process.
