摘要：

Wire and Arc Additive Manufacturing (WAAM), which exhibits high deposition rate and low production cost, is a promising method for fabricating large-sized composite components. In this work, the WAAM process is applied to fabricate steel matrix composite components by introducing WC/Fe powder into the molten pool through gravity-driven side powder feeding. The effects of WC powder fraction on the microstructure, mechanical properties and wear resistance of deposited components have been investigated. The results reveal that WC particles are completely dissolved into the matrix for the specimen...
