摘要
通过研究浇注温度对砂型铸态ZL210A合金力学性能、金相组织和断口形貌的影响。结果表明,浇注温度对ZL210A合金力学强度、硬度值和合金断口形貌影响不大,对合金延伸率略有影响,晶界上析出的共晶相随着浇注温度的提高而增多,合金铸态组织主要为α(Al)和θ(Al2Cu)相。
The effect of different casting temperatures on the mechanical properties, microstructures and fracture surfaces of the ZL210A casting aluminum alloy was investigated. The result shows that casting temperatures have no influence on the tensile strength, hardness and fracture surfaces of the ZL210A alloy and a little influence on the elongation. The eutectic phase on grain boundary increases as casting temperature increasing. Phase constituents of as-cast alloy were composed of α（Al） and θ（Al2Cu） phase.
