Some aspects on geometric and matrix work-hardening characteristics of sintered cold forged copper alloy preforms [PDF]

Materials Research, 2013
Powder metallurgy (P/M) material subjected to plastic deformation results into densification, however the extended deformation would not only enhance the densification also supplements the strain hardening.

Phenomenological Modeling of Deformation-Induced Anisotropic Hardening Behaviors: A Review

Metals, 2023
Numerous studies indicate that the hardening behaviors of materials are closely related to their deformation history. In the forming processes with loading path changes, such as sheet metal forming, anisotropic hardening behaviors are universally ...

Justification of the Changes in Work Hardening Exponent Based on Micro-Mechanisms of Deformation in a Plain Carbon Steel [PDF]

Archives of Metallurgy and Materials
Although several studies have been conducted on the evaluation of work hardening behavior of dual-phase steels with the Hollomon equation, few studies have investigated the factors affecting the number of work hardening stages and the changes of work ...

Impact of Short-Range Clustering on the Multistage Work-Hardening Behavior in Cu–Ni Alloys

Metals, 2019
The work-hardening behavior of Cu⁻Ni alloys with high stacking-fault energies (SFEs) is experimentally investigated under uniaxial compression. It is found that, with the increase of Ni content (or short-range clustering, SRC), the flow stress of ...

Dislocation Formation and Work-Hardening in Two-Phase Alloys [PDF]

, 2004
A phase field model is presented to investigate dislocation formation (coherency loss) and workhardening in two-phase binary alloys. In our model the elastic energy density is a periodic function of the shear and tetragonal strains, which allows multiple

Effects of Sequential Operation with Heat Treatment and Mechanical Milling on Work Hardening for Superalloy GH4169

Metals, 2021
Engineering components are usually manufactured with sequential production processes. Work hardening due to previous production processes affects the machinability of the workpiece in subsequent operations. In this research, the surface work hardening of
