- Abstract
Indentation-flattening compound deformation technology (IFCDT) is defined, and the characteristics and stress-strain state of IFCDT are analyzed. The mechanism of grain refinement and texture weakened of AZ31 magnesium alloy sheet which deformed by IFCDT is analyzed. The influence law of parameters of IFCDT on microstructure and mechanical property of AZ31 magnesium alloy is studied by experiment. The parameters of IFCDT are determined, and the tools of IFCDT are manufactured. It is analyzed that the effect of deformation temperature and reduction ratio on the microstructure and mechanical property of AZ31 magnesium alloy which deformed by IFCDT. The results show that the microstructure and mechanical property of magnesium alloy sheet had been improvement by processed of IFCDT. When deformation temperature is 275 oC and the reduction ratio is 29 %, and the tools temperature is 150 oC, the average grain size is 7.84 um, and yield strength is 212 MPa, and tensile strength is 298 MPa, and the elongation ratio reached 17.2 %. Compared with that of ordinary rolling state, the average grain size of IFCDT had been reduced 23 %, and yield strength had been increased 5 %, and tensile strength had been increased 15 %, and the elongation ratio had been increased 4 %, and the hardness had been increased 12 %
