Study on heat treatment of copper alloy for fabrication of specialized copper based items

Abstract

The article studied the effect of different heat treatment regimes on the microstructure and mechanical properties of copper alloy for fabrication of specialized copper based items. The microstructure of the materials was evaluated by optical microscopy on the Axiovert 40MAT instrument. The effect of microstructure on the mechanical properties of the alloy was evaluated through hardness. The results of the research showed that annealing stage greatly affected to the microstructure and properties of the material in the production process of copper cones. The annealing temperature was bansed on deformation process and maintained at temperature of between 280 ^oC ÷ 400  ^oC to ensure the small grain size, grain grade of higher than 8.
