Effect of Sc addition and T6 aging treatment on the microstructure modification and mechanical properties of A356 alloy
TL;DR: In this paper, the effect of Sc addition and T6 aging treatment on the secondary dendritic arm spacing (SDAS), modification of eutectic Si morphology, β-Al 5 FeSiand π-Al 8 Mg 3 Si 6 Fe 1 phases and its effect on mechanical properties in A356 alloy has been investigated.

TL;DR: In this article, the effect of normalizing and tempering (CNT) and double austenitization-based normalizing-and-tempering (DNT) heat treatments on the microstructure, tensile, creep and impact toughness properties of 9Cr-1Mo steel has been studied.
Journal ArticleDOI
Influence of W and Ta content on microstructural characteristics in heat treated 9Cr-reduced activation ferritic/martensitic steels
TL;DR: In this paper, the microstructural changes due to variation of W and Ta content and heat treatment in 9Cr-W-Ta-0.2V-C reduced activation ferritic/martensitic steels.
Journal ArticleDOI
Microstructure and mechanical properties of as-cast and T6 treated Sc modified A356-5TiB2 in-situ composite
TL;DR: In this article, the effect of Sc addition on the secondary dendritic arm spacing, eutectic Si modification, intermetallic phase modification, aging behavior and subsequently the mechanical behavior in A356-5TiB2 in-situ composite was presented.
Journal ArticleDOI
Friction welding of mild steel and titanium: Optimization of process parameters and evolution of interface microstructure
TL;DR: In this paper, a defect free bonded interface between mild steel (MS) and titanium (Ti) using the rotation friction welding process was constructed using several trials by varying friction welding parameters like frictional force, upset force, burn-off length and rotational speed.
