In order to study the influences of liquid die forging parameters on the microstructure and wear behavior for ADC14 aluminum alloy, the liquid forging pressure (60, 90 and 120 MPa), degree of superheat(50,100 and 150 ℃) and preheating temperature of mold(200, 250 and 300 ℃) were chosen as three independent variables,and the microstructure characteristics, weight loss of specimen and change of friction coefficient after wear tests were observed and analyzed. The test results show that the liquid die forging pressure, degree of superheat and preheating temperature of mold have a significant effect on the microstructure and wear performance of alloy. The increaseing of liquid die forging pressure promotes the refinement of microstructure, but when the pressure exceeds a certain value, the influence on the refinement of microstructure decreases. Variations in the preheating temperature of mold and the degree of superheat affect the quantity and shape of primary Si phases. The increasing of liquid die forging pressure also effectively reduces the wear of alloy, especially at the liquid die forging pressure of 120 MPa and the mold preheating temperature of 300 ℃, the mass loss of alloy is the smallest. Thus, the appropriate adjustment of the liquid die forging parameters effectively improves the microstructure and wear performance of ADC14 aluminum alloy, which provides a reference for the optimization and industrial application of liquid die forging for ADC14 aluminum alloy.
