Study on Microstructure and Properties of the Extruded Beryllium at Different Temperatures and Proposals for Extrusion Process AITranslate
Abstract AITranslate
The study was carried out on the effect of extrusion temperature on microstructure and properties of beryllium material and its texture evolution during extrusion. The results show that the crystal grains of beryllium ingot are refined after extrusion, and its tensile strength, yield strength and fracture elongation are improved in different degrees. With extrusion temperature increasing, beryllium grain size increases and （1010） fiber texture is enhanced, both affecting the mechanical properties of beryllium rods. In order to ana- lyze the relationship between mechanical properties, crystal structure and texture of extruded beryllium rods, mechanical testing was carried out with the samples obtained according to a certain slope angle along the extrusion direction. It is found that the tensile strength and yield strength significantly decrease, while the fracture elongation greatly increases. Therefore, the plasticity of beryllium material can be improved by controlling texture direction via equal channel extrusion.
