Journal ArticleDOI
Microstructure and mechanical properties of the austenitic stainless steel 316L fabricated by gas metal arc additive manufacturing
TL;DR: In this article, the microstructure and room temperature tensile properties of GMA-AM 316L were investigated and the fracture type is ductile fracture due to the obvious fracture surface dimples.
Journal ArticleDOI
Effect of heat treatment on microstructure, mechanical and corrosion properties of austenitic stainless steel 316 L using arc additive manufacturing
TL;DR: In this article, the volume fractions of sigma (σ) and delta-ferrite (δ) phases through heat treatment were modified to improve the mechanical and corrosion properties of GMA-AM 316L.
Journal ArticleDOI
Microstructural control during laser additive manufacturing of single-crystal nickel-base superalloys: New processing–microstructure maps involving powder feeding
TL;DR: In this paper, the effects of powder feeding during laser additive manufacturing (LAM) of single-crystal (SX) nickel-base superalloys were considered and a simple and feasible strategy was presented to deal with the effect of powder-feeding and to extend the combined numerical model used to calculate processing-microstructure maps.
Journal ArticleDOI
A new microsegregation model for rapid solidification multicomponent alloys and its application to single-crystal nickel-base superalloys of laser rapid directional solidification
TL;DR: In this paper, a new micro-segregation model for rapid solidification multicomponent alloys was developed to predict the microsegregation in the single-crystal superalloys of laser rapid directional solidification.
Journal ArticleDOI
Prediction of primary dendritic arm spacing during laser rapid directional solidification of single-crystal nickel-base superalloys
TL;DR: In this paper, a combined numerical model was developed to investigate the influence of laser processing parameters on the primary dendritic arm spacing (PDAS) feature in the nickel-base single-crystal (SX) superalloys by laser rapid directional solidification (LRDS).
