摘要
研究了大高径比(M=H/D=7)ZA27合金铸件的柱塞式挤压铸造。主要分析了挤压铸造工艺参数对大高径比ZA27合金的通体力学性能和显微组织影响规律,初步确定了适合大高径比ZA27合金铸件柱塞式挤压铸造的工艺参数。试验结果表明,挤压铸造能够改善大高径比ZA27合金铸件的通体力学性能,为扩大锌铝合金的应用范围提供了有力的技术保证。
The fundamental problem of plunger type squeeze ZA27 alloy castings with high ratio of height to thickness ( M = H/D = 7 ) was investigated. The influence of squeeze casting parameters on the mechanical properties and microstructure of ZA27 alloy was analyzed. The plunger type squeeze casting parameters fitting for ZA27 alloy with high ratio of height to thickness is preliminary decided. Squeeze casting improves the mechanical properties of ZA27 alloy and offers important maintenance logistics for developing the applied range of ZA alloys.
