A flexible solution method for the initial-boundary value problem of the temperature field in a one-dimensional domain of a solid with significantly nonlinear material parameters and radiation boundary conditions is proposed. A transformation of the temperature values allows to isolate the nonlinear material characteristics into a single coefficient of the heat conduction equation. The Galerkin...

Abstract 18Ni-300 maraging steel manufactured by selective laser melting was plasma nitrided to improve its wear and corrosion resistance. The effects of a prior solution treatment, aging the combination both on microstructure properties after nitriding were investigated. results compared with conventionally produced counterparts subjected same heat- thermo-chemical treatments. performed under ...

The purpose of this research was to analyze and compare the mechanical properties of parts made using both Direct Metal Laser Sintering (DMLS) and traditional manufacturing methods like casting or forging. Previous research in DMLS was conducted using various materials, but there has been very little done for 17-4PH stainless steel. All the samples used for testing were conducted using the EOSI...

In the conventional continuous casting of steel, either mold powder or oil can be added to lubricate the mold from sticking to the solidifying steel shell. The mold powder melts to form a molten slag or flux layer, and also acts to protect the molten steel from oxidation, to insulate the molten steel from heat loss, to absorb inclusions from the molten steel, to regulate heat transfer to mold w...

Axial fully-reversed strain-controlled ([Formula: see text]) fatigue experiments were performed to obtain data demonstrating the effects of building orientation (i.e. vertical versus horizontal) and heat treatment on the fatigue behavior of 17-4 PH stainless steel (SS) fabricated via Selective Laser Melting (SLM) (Yadollahi et al., submitted for publication [1]). This data article provides deta...

Fracture at sheared edges upon stretch flanging is a severe problem for ultrahigh-strength steel (UHSS). This study was focused on the improvement of flangeability by heat treatment edge UHSS samples. The materials studied were dual-phase and full martensite steel. samples pierced with 10 mmΦ holes then heat-treated whole-area or partial-area heating. heated tested hole expansion test to determ...
