The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2007 Stainless austenitic steels have a good corrosion resistance but reduced abrasion strength due to low strength below 200 HV5. By nitriding one may ensure the obtaining of a superficial layer with increased strength that should maintain unaltered the ...

The Influence of Austenite Grain Size on the Mechanical Properties of Low-Alloy Steel with Boron
, 2017 This study forms part of the current research on modern steel groups with higher resistance to abrasive wear. In order to reduce the intensity of wear processes, and also to minimize their impact, the immediate priority seems to be a search for a ...

Advanced Engineering Materials, EarlyView.In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

Advanced Engineering Materials, EarlyView.A simulative evaluation of triply periodic minimal surface (TPMS) structures for an elastocaloric application under compressive load is performed. For the evaluation of the structure's performance, surface/volume ratio, generated heat and invested mechanical work are taken into account and are compared to a tube as a reference specimen.

Comparative Study of Experimental Methods for Measuring Thermal Properties of 100Cr6 Steel Powders
Advanced Engineering Materials, EarlyView.This study investigates the thermal properties of 100Cr6 steel in both bulk and powder forms. Measuring the very low thermal conductivity typically exhibited by powders poses significant challenges. To address this, two novel measurement techniques—temperature gradient and finite laser pulse response—are introduced and evaluated by comparison with the ...
