The First-Principles Design of Ductile Refractory Alloys

First Principles Design of Ductile Refractory Alloys

The purpose of this work is to predict elastic and thermodynamic properties of Cr-based alloys based on first-principles calculations and to demonstrate an appropriate computational approach to develop new materials for high-temperature applications in energy systems. In this study, we choose Poisson’s ratio as screening parameter for identifying ductilizing additives to the refractory alloys. ...

Structural and Mechanical Characterization of Austempered Cu - Sn Ductile Iron Alloys

The effect of heat treatment and alloying elements of copper and tin on the microstructure and mechanical properties of austempered ductile cast iron alloys is investigated. The austenitizing temperature of 890°C, the isothermal transformation (austempering) temperatures of 285, 335 and 375°C, and austempering times of 15, 30, 75 and 150 minutes are studied. The alloying elements of copper and ...

Mechanical properties of Ni-based solid solution alloys: A first principles study

Present work describes the structural stability and mechanical properties of Ni-based binary and ternary alloys. These alloys have been evaluated using first principles density functional theory (DFT) within generalized gradient approximation (GGA). The equilibrium lattice constant values of the phase in these alloys are in good agreement with the experimental data obtained by X-ray diffraction...
