Preparation and Characterization of Ti‐6‐4 and Ti‐8‐1‐1 Metal Matrix Composites with High Specific Stiffness Using Powder Hot Extrusion and Arc Remelting

Advanced Engineering Materials, Volume 26, Issue 14, July 2024.
Powder hot extrusion and heat treatment of titanium metal matrix composite's lead to high specific stiffnesses of 34.6 GPa cm3 g−1. Remelting, to simulate an additive manufacturing method, of these materials results in severe changes of the microstructure and a decrease in the mechanical properties even with ex situ reinforcements. Titanium alloys with
