Physical, mechanical and dry sliding wear properties of an Al-Si-Mg-Ni-Cu alloy under different processing conditions
چکیده انگلیسی
In pressurized solidification, the air gap formation due to shrinkage eliminated and heat transfer and cooling rate increased considerably. This effect resulted in a significant microstructure refinement and improvements in the mechanical properties of castings. Pressure also affects the freezing temperature of the alloy. A new version of the Clausius-Clapeyron equation was proposed to determine the extra pressure-induced undercooling. The results showed that pressurized sample exhibit a much stronger tendency to return to its equilibrium state. Improvement the wear response of pressurized cast sample is another effect of applied pressure.
