铸造工艺会直接影响材料的力学性能和组织,基于计算机模拟的实验装置对不同铸造工艺条件下硅铝合金材料进行凝固组织分析。研究发现:保温温度越低,等轴晶区的转变位置就会越小,等轴晶区的晶体会增大,等轴晶区的晶体形核率会提高;不同的冷却条件会产生不同的冷却组织,在水冷和油冷条件下比在空气冷却的条件下产生组织的等轴晶区的晶体变大,等轴晶区的晶体形核率会有一定程度的提高,等轴晶区的转变位置也会增大,水冷条件比油冷条件更为明显。
Casting process will directly affect the mechanical properties of materials and organizations, based on the computer simulation of experimental devices for different casting conditions silicon aluminum alloy materials for solidification microstructure analysis. The results show that the lower the holding temperature, the smaller the position of the equiaxed zone will be, the larger the equiaxed zone will be, and the nucleation rate will increase in the equiaxed zone. Different cooling conditions will produce different In the cooling structure, the crystals in the equiaxed zone where the microstructure is formed under water-cooling and oil-cooling conditions become larger than those in the air-cooled condition, and the nucleation rate in the equiaxed zone increases to a certain extent. The equiaxed zone Change the location will increase, water-cooled conditions more pronounced than oil-cooled conditions.
