【Abstract】 The addition Of trace element Na to an Al-Si alloy results in the modification of the Al-Si alloy and changes the microstructure and the eutectic temperature of the Al-Si eutectic alloy in comparison with that without Na.For a further study on the rule of modification of the Al-Si alloy, we gave the metastable equation of the Al-Si system, determined and calculated the eutectic temperature of the Al-Si system with the addition of trace Na. The result of experiments tallys well with that of calculation.更多还原
