Effect of friction stir processing on the structure and properties of a bronze-steel composite material
摘要
The paper studies the effect of friction stir processing (FSP) on the structure and properties of a bronze-steel composite material fabricated by wire-feed electron beam additive manufacturing (EBAM). The efficiency of the hybrid approach is demonstrated, allowing the formation of gradient structures with a hardened surface layer and a high degree of homogenization. FSP leads to significant grain refinement, increased microhardness, and an increase in the yield strength, while maintaining plasticity. The obtained results confirm promise for using EBAM in combination with FSP for creating wear-resistant surface structures in copper alloys. The method has high potential for practical application in mechanical engineering and the transport industry.
