Study on Mechanic Behavior of SC100-T6 Under Hot-working Conditions
The stress varying rules of SC100-T6 high silicon aluminum alloy during high temperature plastic deformation were studied by isothermal compression of cylindrical specimens on Gleeble-1500. The experiment temperature is from 360 ℃ to 500 ℃, strain rate is from 0.006 s-1 to 0.036 s-1. The results show that the flow stress is effected by the changes of both strain rate and deformation temperature, the flow stress decreases with the increase of temperature, while increases with the increase of strain rate. The flow stress of SC100-T6 alloy during high temperature deformation can be represented by a Zener-Hollomon parameter in sinh form.
