Comparison of mechanical properties and microstructure of annealed and quenched ti-6Al-4V alloys

Abstract

Ti-6Al-4V alloys with different diameters (d= 3 or 5 mm) were fabricated by suction casting. The microstructure of alloys was characterized by optical microscopy and scanning electron microscopy. The different diameters lead to different cooling rates resulting in significant changes in microhardness.
