Both a Ti-15% V alloy and a Ti-35% V alloy are heated to the lowest temperature at which all b just forms. They are then quenched and reheated to 300°C. Describe the changes in microstructure during the heat treatment for each alloy, including the amount of each phase. What is the matrix and what is the precipitate in each case? Which is an age-hardening process? Which is a quench and temper process? [See Figure.]
