Abstract: AISI 316L steel and Inconel 718 are metals of wide application in industries. The study dissimilar welding between these two materials is technologically important to improve their joint performance. We focused this on the evaluation weldability materials. Three samples welded using a multipass GTAW (Gas Tungsten Arc Welding) process with different parameters were analyzed. microstruc...

In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, ...

The present work explores for the first time additive manufacturing of powder mixtures consisting Chromium Nitride (Cr2N) and AISI 316L with laser bed fusion (L-PBF). addition 2.5 wt% Cr2N to an resulted in successful dissolution both chromium nitrogen into a fully austenitic stainless steel microstructure. content was augmented from 0.09 as-delivered 0.31 L-PBF built part, causing slight expan...

Additive manufacturing (AM) is spreading in a wide range of industrial fields. The influence the printing parameters on mechanical performance still an open issue among researchers, particularly when dealing with fatigue loads, which can lead to unexpected failure. Classical tests require large amount time and materials be consumed. Compared traditional assessment, thermographic method (TM) abl...

Abstract In this study, the effect of kinetic energy shot peening process on microstructure, mechanical properties, residual stress, fatigue behavior and stress relaxation under loading AISI 316L stainless steel were investigated to figure out mechanisms crack initiation failure. Varieties experiments applied obtain results including microstructural observations, measurements hardness, roughnes...
