High pressure solidification process and effect on nanohardness of Ti-48 at-%Al alloy.

<title/> In this work a tungsten carbide six-anvil apparatus was introduced to investigate the high pressure solidification effect on Ti-48 at-%Al alloy. The experimental processes of Ti-48 at-%Al alloy solidified under different pressures were presented in detail. The mechanical properties of Ti-48 at-%Al alloy solidified under different pressures were examined by a Nanoindentor XP tester. It shows a certain increase in the nanohardness of the lamellar structure as the pressure increases from normal pressure to 4 GPa. When the pressure is 4 GPa, the nanohardness increases by 50·2% compared with that of normal pressure. [ABSTRACT FROM AUTHOR]
