Effect of Initial Microstructure on Mechanical Properties of Pressure Vessel Steel after Intercritical Heat Treatment
The influence of the initial structure on formation of austenite, evolution of structure, and elevation of operating characteristics of steel SA508 Gr.3 (0.24% C, 1.40% Mn, 0.88% Ni, 0.54% Mo) after an intercr...

Granular Carbides-Assisted Ultrafine-Ferrite Fabrication in the Pearlitic Steel Without Severe Plastic Deformation and Annealing
The evolution of ferrite grain and cementite lamella during cold rolling in a granular carbide–pearlite steel has been investigated. Particular attention has been given to a quantitative characterization of ch...

Thermal expansion-adjustable carbon-doped FeCoCrNiMn high-entropy alloys for electronic packaging
Application of an electronic packaging material is always limited by its established coefficient of thermal expansivity (CTE) and poor plastic working capacity. Here, we explored that a ductile high-entropy al...

Effect of Annealing Temperature on Microstructure and Mechanical Properties of a Severe Cold-Rolled FeCoCrNiMn High-Entropy Alloy
An ultrafine-structured FeCoCrNiMn high-entropy alloy (HEA) was produced by severe cold rolling (SCR) with a 95 pct reduction, and the effect of annealing temperature over a wide range from 573 K to 1373 K (30...

Mechanical Behavior of Ultrafine-Grained Ti-6Al-4V Alloy Produced by Severe Warm Rolling: The Influence of Starting Microstructure and Reduction Ratio
To provide insight into the mechanical behavior and microstructural evolution of bulk ultrafine-grained (UFG) Ti-6Al-4V alloys, we produced Ti-6Al-4V alloy sheets with grain size smaller than 300 nm through se...
