Abstract
The influence of heat treatment on the mechanical behavior in terms of true stress-strain and mode of fracture of the deferent non-heat-treatable alloys has been carried out.Hardness, resistivity and the microstructural change of the alloys due to annealing also consider for complying the properties.In this purpose the hot rolled followed by cold rolled alloys samples are isochronally annealed for one hour at different temperatures.The experimental results show that maximum strength can be achieved by 5xxx series alloys followed by 3xxx, 4xxx and the lowest for 1xxx series alloys as attributed to the alloying element performance.Increasing of heat treatment temperature led to decrease in hardness and resistivity of the alloys by reason of recovery and coarsened the grains.The stress-strain curves show…
