Deformation Theory of Hot-Pressing [PDF]
Journal of Applied Physics, 1967 The possible deformation behavior of spheres in a compact has been both theoretically analyzed and experimentally verified. The change in contact area radius a relative to the particle radius R has been related to the bulk density and bulk strain for four possible modes of packing: simple cubic (Z=6), orthorhombic (Z=8), rhombohedral (Z=12), and body ...

Journal of Materials Research and Technology, 2021 The present work deals with revealing the fatigue and dwell-fatigue behavior and correlated damage mechanisms of Fe–Mn–Al–C lightweight steel. Surprisingly, alteration in loading mode from monotonic to cyclic induces reversible dislocation movement and ...

The effect of Nd-Cu diffusion during hot pressing and hot deformation on the coercivity and the deformation ability of Nd-Fe-B HDDR magnets [PDF]
, 2017 HDDR processed Nd-Fe-B powders blended with Nd-Cu powders were hot-pressed and then hot-deformed to obtain fully dense, anisotropic magnets. The microstructure evolution in hot-pressed and hot-deformed HDDR magnets was studied to illustrate the impact of

On the short-time thermal phase-stability of as-cast AlCoCrFeNi2.1 eutectic high entropy alloy
Journal of Materials Research and Technology, 2022 The present work deals with the short-time thermal phase-stability of the as-cast eutectic AlCoCrFeNi2.1 high entropy alloy. Toward this end, the effect of different temperatures (800–1000 °C) and soaking times (15–60 min) on the stability of primary ...

Numerical Simulation of Deformation in Hot Runner Manifold
Micromachines, 2023 This study simulated the deformation of a hot runner manifold and nozzle assembly during operation, aiming to address potential leaks and premature failure. Both thermal and mechanical models were used simultaneously to accurately capture system behavior. A simplified set of boundary conditions was proposed for efficient problem-solving.

Hot Deformability of Weld Metal
JOURNAL OF THE JAPAN WELDING SOCIETY, 1973 In order to study the mechanism of hot cracking in aluminum alloys, the characteristics of brittle range existing behind the molten pool are investigated experimentally by using special tension executed soon after the welding. As to the characteristics of brittle range in weld metal, length, temperature range and minimum quantity of deformation ...
