Numerical Investigation on the Strain Evolution of Ti-6Al-4V Alloy during Multi-directional Forging at Elevated Temperatures

High Temperature Materials and Processes, 2018
Multi-directional forging (MDF) is one of the most promising severe plastic deformation (SPD) methods used in fabricating large-scale bulk metal materials with ultra-fine grains (UFG). A finite element model for MDF is developed to investigate the strain

Synergistic enhancement of strength and toughness of β-Ti alloy with a fine grain: Effect of deformation temperature [PDF]

MATEC Web of Conferences
It is difficult for as-cast titanium alloys to achieve high strength and toughness due to the presence of coarse β grains. In this study, multi-directional forging (MDF) was employed to break down the coarse β grains into fine grains and the mechanism of

Topological characteristics of grain boundary networks during severe plastic deformations of copper alloys [PDF]

, 2023
The grain boundary character distribution strongly affects the properties of polycrystalline materials. Grain boundaries of similar characters form networks, whose topological invariants can be considered as distribution descriptors.
