Abstract Scope |
Heat treatments are necessary to improve the mecahnical properties of stainless steels (SS). However, a noticeably different starting microstructure has been reported for SS products manufactured using traditional methods as compared to additively manufactured products. This study explores the microstructural differences between wrought SS17-4 PH and that synthesised using the directed energy deposition (DED) technique. The H900 condition was modified for the DED synthesised material to optimise the microstructure. Phase analsysis techniques revealed an increased ferrite phase fraction for the DED material as compared to the wrought material, implying improved corrosion performance. The standard H900 condition applied to the DED material showed reduced ferrite, while the modified condition showed an increase in ferrite fraction. |
