Graphite mold casting is a promising technique owing to its ability to provide high cooling rates and suitability for many types of alloys. The fluidity of A356 aluminum and AZ91 magnesium alloys cast into graphite molds was determined at casting temperatures of 670 °C–810 °C. As expected, the fluidity of AZ91 was lower than that of A356. The critical solid fractions for A356 aluminum and AZ91 magnesium alloys were determined by comparing simulated spiral fluidity test lengths with those obtained experimentally. For graphite mold casting, the critical solid fractions for A356 and AZ91 alloys were in the range of 0.12–0.15 and 0.13–0.17, respectively.

石墨模具中A356和AZ​​91合金流动性的模拟和实验验证

石墨铸模技术是一种有前途的技术,因为它具有提供高冷却速率和适用于多种合金的能力。在670°C–810°C的铸造温度下测定铸造到石墨模具中的A356铝和AZ91镁合金的流动性。不出所料,AZ91的流动性低于A356。通过比较模拟的螺旋流动性测试长度与实验获得的长度,可以确定A356铝和AZ91镁合金的关键固体分数。对于石墨铸模,A356和AZ​​91合金的临界固形分率分别在0.12-0.15和0.13-0.17之间。
