Effects of Mechanical Post-Treatments on Additive Manufactured 17-4PH Stainless Steel Produced by Bound Powder Extrusion
Procedia CIRP(2021)
摘要
Abstract Bound Powder Extrusion (BPE) is increasingly gaining popularity and makes metal additive manufacturing easier and more accessible for industrial production. The Markforged-Metal X technology with debinding and sintering, also called Atomic Diffusion Additive Manufacturing (ADAM), is a newcomer in the field of extrusion additive manufacturing. The main objective of this work is to investigate the mechanical properties of 17-4PH stainless steel samples produced by ADAM. Moreover, the effects of a mechanical post-treatment (SMAT) on surface and mechanical properties are also analyzed. The macroscopic tensile response and superficial residual stresses of as-fabricated and SMATed samples are compared.
