Book Description
Materials strengthened by conventional methods such as strain hardening, solute additions, precipitation and grain size refinement are often adopted in industrial processes. But there is limitation to the amount of deformation that these conventional methods can impact to a material. This study focused on the review of major mechanical properties of aluminum alloys in the presence of an ultrafine grain size into polycrystalline materials by subjecting the metal to an intense plastic straining through simple shear without any corresponding change in the cross-sectional dimensions of the sample. The effect of the heavy strain rate on the microstructure of aluminum alloys was in refinement of the coarse grains into ultrafine grain size by introducing a high density of dislocations and subsequently re-arranging the dislocations to form an array of grain boundaries. Hence, this investigation is aimed at gathering contributions on the influence of equal channel angular extrusion toward improving the mechanical properties of the aluminum alloys through intense plastic strain.

Book Description
Tests were undertaken to evaluate the significance of performing equal-channel angular pressing using a die having an angle of 60 between the two channels. The tests were conducted using samples of pure aluminum arid an Al-1% Mg-O.2% Sc alloy. The results lead to the conclusion that the mechanical properties of samples in the as-pressed condition are similar for both 60 and 90 dies provided the data are compared at the same equivalent strains.

Book Description
The study of superplasticity and superplastic forming (SPF) has been increasing steadily over the past 15 years. This volume examines the current state of the technology with a focus on technological applications of superplastic forming and the mechanistic behaviour of superplastic materials.

Book Description
ABSTRACT: Industry standard 6061 and 6063 Aluminum alloys were processed by equal channel angular extrusion (ECAE) at room temperature using a Bc route with a constant feed rate of 0.25 mm/s through a die angle of 90° between the die channels. The influence of ECAE processing on the evolution of the microstructure, microtexture and microhardness in the material was studied using orientation imaging microscopy (OIM), X-ray diffractometry, and Vickers microhardness testing. Detailed analysis was carried out on samples of the as-received, one, two, four and eight pass conditions.
