Abstract The present work summarizes the results of an experimental campaign aimed at assessing ductility a wrought 17-4PH steel alloy. A simple specimen reproducing multiaxial stress states through universal testing machine is selected. Finite Element Model (FEM) for each test setup to extract local values and strain in most critical point on onset failure. Digital Image Correlation (DIC) tech...

Micro-powder injection molding (μPIM) is a modification of powder (PIM) process and globally recognized manufacturing route that can be used largely to produce sophisticated micro-sized components using wide range metals ceramics. The demand μPIM currently increasing in various applications telecommunication, electronics, aerospace, biomedical, automotive industries. In this research work, sint...

17-4PH stainless steel is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties, good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. This valuable alloy is widely used in the aerospace, nuclear, chemical, pet...

Purpose The mechanical characterization of selective laser melting (SLM) parts is an industrial challenge. This paper aims to propose a methodology control the fatigue life 17-4Ph stainless steel by selecting most relevant manufacturing parameters: i.e. power, travel speed, hatch spacing and defocusing. Design/methodology/approach A rough refined design experiment (DOE) carried out target best ...
