【摘要】:正第一节概述半固态铸造技术是将含有非枝晶固相的固液金属混合物在凝固温度范围内加工成形的一种金属材料成形技术~([1])。与传统金属材料成形方法相比,半固态铸造技术具有如下特点:(1)被加工的材料处于液固共存两相区,一方面,可减少凝固潜热和凝固收缩,有利于实现更精确的近终成形;另一方面,由于成形温度低,减轻了模具的热冲击,提高模具的使用寿命,同时减少了零件凝固时间,提高了零件的成形速度。(2)半固
[Abstract]:In the first section, the semisolid casting technology is introduced. It is a kind of metal material forming technology which is used to form solid liquid metal mixture containing non-dendritic solid phase in the range of solidification temperature. Compared with the traditional metal material forming method, the semi-solid casting technology has the following characteristics: (1) the processed material is in the liquid-solid coexistence two-phase zone, on the one hand, it can reduce the solidification latent heat and solidification shrinkage. It is advantageous to realize more accurate near end forming; On the other hand, because of the low forming temperature, the thermal shock of the die is alleviated, the service life of the die is increased, and the solidification time of the part is reduced, and the forming speed of the part is improved. (2) Semi-solid.
