Additively manufactured materials usually exhibit mesoscale heterogeneities. Mesoscale fluctuations of strain fields in notched samples made 17-4PH Stainless steel and loaded tension are investigated. Regularized digital image correlation enables for the analysis at different length scales. Five tests on specimen fabricated with printing parameters studied. It is shown that have no characterist...

In this study, we focus on making a double-sided metal plate with an internal structure, such as honeycomb. The stainless steel powder was used in the metal injection molding (MIM) process. The preliminary studies were carried out for the measurement of the viscosity of the stainless steel feedstock and for the prediction of the filling behavior through Computer Aided Engineering (CAE) simulati...

To evaluate the interactions between hydrogen and mechanical behavior of additively manufactured (AM) 17-4PH martensitic stainless steel (MSS), stress-relaxation tests were performed for both non-charged hydrogen-charged samples. Similar conventional MSS counterpart (CM). The results clearly indicated significant differences in relaxation properties CM AM MSSs H900 state, which attributed to hi...

As a high-strength corrosion-resistant alloy, stress corrosion cracking (SCC) behavior is key consideration for the conventional, wrought form of 17-4PH stainless steel. With increasing popularity additively manufactured (AM) 17-4PH, understanding SCC AM will be similarly critical its presumed, future applications. The current study quantifies and compares both form, as baseline, at peak-aged (...

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...
