TL;DR: In this article, the feasibility of using the solution Heat treatment, Forming, and in-die Quenching (HFQ) process to produce complex shapes from a sheet magnesium alloy, and to use the results to verify a simulation of the process developed using commercial FE software.

TL;DR: In this paper, a constitutive equation model framework was proposed to predict the distribution of stress of EA4T steel, and the constants arising in this model were determined using an evolutionary programming (EP) optimization technique.

TL;DR: In this paper, the tensile and compressive creep behavior of aluminium alloy 2050 with T34 initial temper (AA2050-T34) during creepageing process has been experimentally investigated and analyzed in detail.

TL;DR: In this article, a set of phenomenological constitutive equations were proposed to predict the stress relaxation phenomena under the same ageing condition, but the stress reduction was significantly over-predicted, suggesting that improvements should be applied to the current modelling method for simulating spring-back after creep age forming.

TL;DR: In this article , the effects of extrusion temperature and velocity on curvature, microstructure, and mechanical properties of the formed profiles were examined, and it was found that profile curvature was more readily controlled by the velocity ratio of the bottom ram v2 to the top ram v1, whereas extrusion temperatures and extrusion velocity (v1 = 0.1, 1 mm/s) slightly affect curvature for a given velocity ratio.
