Microstructures and mechanical properties of Co-based Elgiloy fabricated by wire arc additive manufacturing
Source abstract
Abstract
Wire arc additive manufacturing (WAAM) has emerged as a promising method for additive manufacturing due to its high efficiency and cost-effectiveness. This study aimed to fabricate Co-based Elgiloy by WAAM based on cold metal transfer technology. An 18-layers thin alloy wall was prepared. The microstructure, texture and mechanical properties of the as-deposited samples were investigated. Results indicated that the prepared alloy had good formability and was composed of a single face center cubic structure. The tensile properties of the alloy exhibited anisotropy due to the large number of columnar grains growing along the building direction in the alloy. The tensile samples along the building direction exhibited lower yield strength but better elongation due to the columnar grain growth direction and the softening effect of the remelted zone.
