可以避免金属液卷气。通过大面积、大变形量的精确锻造

能对凝固金属进行有效补缩和压实组织

显著提高铸锻件的组织致密度和力学性能。A356铝合金铸锻件经T6热处理后的抗拉强度达到320～335MPa

比未进行锻造时的抗拉强度平均提高了17%。

Abstract

The characteristics of the casting-forging hydraulic press with 6 000 kN and its die were described.The process of casting-forging and the microstructure as well as mechanical properties of A356 aluminum alloy prepared by the casting-forging technology were investigated.The results show that the casting-forging hydraulic press manufactured by self-designing has multi-functions such as side feeding

press casting and precision forging.The gas-entrappment in the parts can be avoided through the low speed casting.The soundness and the mechanical properties of the parts can be improved significantly through the forging with large area and large deformation.The tensile strength of A356 aluminum alloy parts with T6 heat treatment is 320

35 MPa

increased by 17% compared with that of A356 aluminum alloy parts without forging.
