Nanoindentation Mechanical Properties of a Bi-phase CuZrTiAlNi Alloy.

Mechanical properties of cylindrical bi-phasic high-entropy alloy CuZrTiAlNi (3 mm in diameter) were characterized by nanoindentation test in each phase. The results show that the constituent FCC phase is of low nanohardness (2.35 GPa) and modulus (60.9 GPa), while another constituent phase in the alloy, the HCP phase, shows much higher nanohardness (6.5 GPa) and modulus (115.3 GPa). Creep occurs in both phases during the indentation. [ABSTRACT FROM AUTHOR]
