Abstract:Canning extrusion is an effective way to refine grains, eliminate defects from hot isostatic pressing consolidation and enhance mechanical properties of P/M nickel-based superalloy. The present research constructed the optimized extrusion processing window for superalloy in consideration of extrusion speed, initial billet temperature, and extrusion ratio to provide guidelines for the choice of extrusion parameters. The processing window was built by integrating the results of finite element (FE) simulations, e… Show more
