MICROSTRUCTURE AND MECHANICAL PROPERTIES OF ULTRA-FINE GRAINED AZ31 ALLOY PROCESSED BY ECAP
Acta Metallurgica Slovaca, 2014 Commercial magnesium alloy AZ31 was processed by equal channel angular pressing preceded by hot extrusion (EX-ECAP). Microstructure evolution with strain due to ECAP was investigated by light and transmission electron microscopy. ECAP processing resulted

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling
Advanced Engineering Materials, Volume 27, Issue 21, November 2025.Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

Deformation Behavior of La2O3‐Doped Copper during Equal Channel Angular Pressing
Advanced Engineering Materials, Volume 27, Issue 20, October 2025.By additions of strengthening elements and/or structure optimization, the mechanical properties of copper can be increased while keeping favorable electric conductivity. By combining addition of La2O3 and processing by equal channel angular pressing, substructure development is achieved, leading to increase in microhardness to more than double the ...

A New Contact Algorithm for the Total‐Lagrangian Material Point Method
International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.ABSTRACT The Total Lagrangian Material Point Method (TLMPM) is a relatively new variant of the now popular MPM, a method to solve partial differential equations appearing in solid and fluid mechanics problems. In TLMPM, each solid has its own grid, and all calculations are carried out in a configuration of reference, often the original configuration ...
