摘要
文章研究了铍铝合金挤压成形技术,分析了挤压成形的影响因素,并观测了挤压组织微观结构,测试了铍铝合金挤压力学性能。研究发现,铍铝合金铸锭经过热挤压成形之后,力学性能有明显改善。但由于影响因素较多,较难获得理想的挤压工艺。
In this paper,the technology for extrusion molding of beryllium-aluminum alloy was discussed; the influence factors in extrusion were analyzed; The microstructure of the extruded beryllium-aluminum alloy was observed by metallograph,and mechanical properties of the extruded alloy was tested too. The results showed that after extrusion,the mechanical performance of beryllium-aluminum alloy was improved,but ideal extrusion process was hard to achieve because of enormous complexity.
