Ti6554合金铸锭挤压工艺研究
Research on extrusion process of Ti6554 alloy ingot
摘要
Abstract
In this paper,the influences of extrusion temperature and extrusion ratio on the microstructure and properties of a new type of small-sized β titanium alloy Ti6554 bar during extrusion were explored.By manipulating different processing parameters,the internal microstructure and the factors affecting the material properties were analyzed.The results indicate that the grains of the alloy are refined significantly at a higher extrusion ratio and a more appropriate extrusion temperature,thereby enhancing the mechanical strength and overall performance of the material.In this study,to concurrently consider the degree of grain refinement after extrusion and the mechanical properties at room temperature and avoid small deformation during utilization,the optimized extrusion process parameters of Ti6554 titanium alloy are as follows:extrusion temperature 1 080 ℃,extrusion ratio 4,and extrusion speed 30～45 mm/s.关键词
