Microstructure and high temperature deformation of an ultra-fine grained ECAP AA7075 aluminium alloy
Publikováno v:
International Journal of Materials Research. 104:3-10
An AA 7075 aluminium alloy with an ultra-fine grained structure was prepared through equal channel angular pressing (ECAP) at pressing temperatures TECAP of 120, 170, and 220 °C. A decrease in TECAP from 220 to 120 °C was found to lead to a more pr

An AA 7075 aluminum alloy with Zr and Sc additions was subjected to 6 – 8 passes of equal-channel angular pressing at 120, 170, and 220 °C in order to study the effect of the pressing conditions on the microstructural characteristics and the conse

Samples of a 7075 aluminium alloy were prepared by the equal-channel angular pressing (ECAP) technique. The channel had a 10 mm × 10 mm cross section and an angle of 90°. A total of six passes was performed using route BC. The ECAP processing was c

The high temperature plastic deformation of twin-roll cast AlMg3 (AA5754) sheets was investigated. The maximum value of the strain rate sensitivity parameter m = 0.4 suggests superplastic behaviour. However, the maximum ductility of 135% remains belo

Equal-channel angular pressing (ECAP) at 443 K was used to introduce an ultra-fine grained (UFG) microstructure to a Zr and Sc modified 7075 aluminum alloy. Using the methods of TEM and EBSD, an average grain size of 0.6 1m was recorded after the pre
