| ABSTRACT Microstructural evaluation and wear characteristics of solution treated Ti-6Al-4V alloy have been investigated. The material was produced using vacuum induction furnace and then applying hot rolling at 900 °C to reduce the samples thickness from 30 to 12 mm. One part of the material was water-quenched from a temperature above - transus at 1100 °C/60 min. to produce a beta lamellar microstructure imbedded in some alpha phase. The other part was water quenched from a temperature below - transus at 950 °C/60 min. to generate an equiaxed microstructure. The fine lamellar structure resulted in ultimate strength and wear resistance significantly superior to the equiaxed microstructure. The overall best combination of hardness, tensile properties, and wear resistance of the studied Ti-6Al-4V is achieved by solution treatment at 1100 °C/60 min. and the lowest values were obtained for the as-cast structure due to the heterogeneity in structure and large grain size that ranged from 350 to 50 μm. | ||||
