The effect of deformation route in equal channel angular pressing on mechanical properties of aluminum alloy 1050
Languages of publication
Annealed samples of commercial purity aluminium (1050) were processed by Equal Channel Angular Pressing (ECA P) at room temperature for up to eight passes. ECA P was conducted by using three processing routes (schemes). Tensile tests and micro hardness were conducted to evaluate variation of mechanical properties after each pass. Analysis of fractography was carried out due to investigate a fracture of the samples. The results showed that all the schemes had similar micro hardness values – around 50 HV. The tensile test results showed that the highest yield strength was achieved in the second scheme after eight passes – 186 MPa – while elongation maintained at the level of 17.4%. The value of yield strength achieved increased more than six times in proportion to annealed condition.
