Aging Behaviour and Mechanical Properties of a Solution Treated and ECAP Processed 6082 Alloy
A study was carried out on the aging behaviour of a solution treated 6082 aluminium alloy deformed by equal channel angular pressing up to six passes. Aging of the so obtained ultrafine alloy was studied by DSC and TEM analyses as well as by isothermal treatments at 130, 160 and 180 C. The results showed that the formation of metastable 00 and 0 precipitates were markedly anticipated and that t...
متن کاملMicrostructures and mechanical properties of ultrafine grained 7075 Al alloy processed by ECAP and their evolutions during annealing
Microstructures and mechanical properties of equal-channel angular pressing (ECAP) processed and naturally aged ultrafine grained (UFG) and coarse grained (CG) 7075 Al alloys as well as their evolutions during annealing were investigated. After the same natural aging, the tensile yield strength, ultimate strength, and microhardness of the UFG samples were 103%, 35%, and 48% higher, respectively...
متن کاملMechanical Properties and Microstructure Development of Ultrafine-grained Cu Processed by ECAP
Technical purity Cu (99.95 wt%) polycrystals have been processed at room temperature by equal channel angular pressing. The results of mechanical tests and the microstructure characterization by various experimental techniques are presented. The yield stress as well as the strength were shown to increase with increasing strain and exceed the respective values of a coarse-grained material. The m...
