Abstract

The BEPE internship project proposed here aims to improve Santana's thesis by characterizing the high temperature mechanical behavior of previously designed precipitation-hardened HEAs through a Gleeble Thermal-Mechanical system. Besides, computational methods will be used to gain an in-depth understanding of the effect of iron additions on the antiphase boundary energy (APB) of Al-Ti-Cr-Co-Ni system.
