Characterization of fully lamellar Ti6Al-4V alloy

Abstract

The high mechanical strength of the lamellar Ti-6Al-4V extruded rod was characterized. The grain morphology of the extruded Ti-6Al-4V rod was investigated by optical microscopy. The microstructure of Ti-6Al-4V alloy consists of very fine α lamella of approximately 2.5 µm in thickness and β lamella with 1 µm thickness. Besides, a numerical model has been presented that reproduces the morphology of the lamellar colonies. In particular, the representative volume element with 512 elements, 4096 elements and, 32768 elements are studied with the C3D8 linear element. Experimental and numerical comparisons of the lamellae morphology have been presented.
