摘要: 根據觸變鑄造半固態合金的流變特性,將半固態觸變成形過程的流動簡化為均相等溫層流流動,并對其進行了數值模擬和實驗驗證,數值模擬結果與實驗充型結果基本相符.Abstract: Based on floe-varying characteristics of thixotropic casting semisolid alloys, the flowing state of the semisolid alloy and the procedures as filling up the mould by means of thixotropic casting being performed, is simplified to the flow which features in an equal temperature layers, audit also is simulated and verified. The analogical results corresponds to that of filling up mould.
