The recent developments in additive manufacturing (AM) are providing unprecedented opportunities various fields, including the fabrication of advanced materials for tribological applications. present work describes results an exploratory study focused on analysis 17-4 PH steel surfaces obtained using selective laser melting (SLM). In particular, includes baseline (as-produced) and textured surf...

Direct energy deposition (DED) is a widely accepted additive manufacturing process and possible alternative to the subtractive processes due its high flexibility in fabricating new 3D parts. DED enables manufacture of complex parts without using costly time-consuming conventional processes, even though building parameters need be accurately determined. In present investigation, effect different...

Purpose – The purpose of this paper is to understand the effect of four different factors: building orientation, heat treatment (solution annealing and aging), thermal history and process parameters on the mechanical properties and microstructural features of 17-4 precipitation hardening (PH) stainless steel (SS) parts produced using selective laser melting (SLM). Design/methodology/approach – ...

To investigate the hot deformation behavior of 17-7 PH stainless steel, hot compression tests were carried out at the temperatures of 950, 1050 and 1150 oC and strain rates of 0.001 s-1 to 0.1 s-1. Accordingly, the hot working behavior was studied by the analyses of flow stress curves, work hardening rate versus stress curves, exponent- type constitutive equations and deformed microstructures. ...
