Journal ArticleDOI
Influence of refined hierarchical martensitic microstructures on yield strength and impact toughness of ultra-high strength stainless steel
TL;DR: In this article, the hierarchical martensitic features in ultra-high strength stainless steel (UHSSS), including the prior austenite grains, martensite packets, blocks and laths with the descending size, were refined to various extents by employing different thermomechanical processes and then carefully characterized.
Journal ArticleDOI
Effect of Ni content on the microstructure and mechanical properties of weld metal with both-side submerged arc welding technique
TL;DR: In this article, the effects of Ni content on the mechanical properties and microstructure evolution in the weld metals of commercial K65 oil and gas pipeline steel were studied, and the authors attributed the formation of predominant acicular ferrite (AF), at the expense of grain boundary ferrite, ferrite side plates (FSP), and martensite/austenite (M/A) constituent in weld metal.
Journal ArticleDOI
Hot deformation characterization of ultrahigh strength stainless steel through processing maps generated using different instability criteria
TL;DR: In this article, four types of processing maps were constructed according to the Murty and Rao (M-R), Kumar and Prasad (K-P) instability criteria, Gegel, Alexander and Malas (A-M) stability criteria respectively.
Journal ArticleDOI
Machine learning guided automatic recognition of crystal boundaries in bainitic/martensitic alloy and relationship between boundary types and ductile-to-brittle transition behavior
TL;DR: In this paper, a gradient boosting decision tree (GBDT) was used for the first time to automatically recognize and conduct quantitative statistical analysis of boundaries in bainitic microstructure using electron back-scatter diffraction (EBSD) data.
Journal ArticleDOI
Solidified microstructures and elastic modulus of hypo-eutectic and hyper-eutectic TiB2-reinforced high-modulus steel
TL;DR: In this paper, the elastic modulus and density of both hypo-eutectic and hyper-eUTectic reinforced high-modulus steels (HMS) with different TiB 2 fractions were investigated.
