Abstract

The effect of the anneal temperature on the microstructure, micro-texture and mechanical properties of the hot rolled Ti-6Al-4V alloy were investigated. The results show that the as rolled Ti-6Al-4V alloy presents a bimodal microstructure. The content of equiaxed α-phase increased after annealing. The content of secondary α-phase tented to decrease, whilst to be gradually spheroidized. The microstructure transformed into equiaxed structure after annealing at 900℃. With the increase of anneal temperature, the preferred orientation of α-phase were changed. Correspondingly, the micro-texture changed from B-type to mixed texture, then to B-type again. The crystal directions dispersed when the sample anneal at 800℃. The texture consisted of {0001}<3 $1 ¯$ $2 ¯$ 0>, {0001}<9 $8 ¯$ $1 ¯$ 0>, {0001}<3 $1 ¯$ $2 ¯$ 0> and {0001}<1 $2 ¯$ 10>. The relationship between the mechanical performance and the annealing temperature were assessed via tensile tests. It follows that with the increased of annealing temperature, the tensile strength increased but the yield strength decreased, spontaneously, the ratio of yield strength to tensile strength decreased. In a word, the comprehensive mechanical properties of the alloy may be enhanced through proper annealing process.
