Abstract:
The effect of equal channel angular pressing (ECAP) on high-temperature compressive deformation and damage behavior of LY12 Al alloys was studied. It is found that the ECAP and temperature have noticeable effects on the compressive deformation and damage behavior of the LY12 Al alloys, especially in the case that the testing temperatures are near and above recrystallization. With the increase of ECAP passage, grains are refined significantly and the plastic deformation ability of the LY12 Al alloys is thus enhanced obviously. With increasing compressive temperature, obvious grain coarsening occurs in ECAPed samples and the plastic deformation capacity is greatly strengthened.
