| Abstract Scope |
Multi-principal element alloys (MPEAs) are, in general, noted for their superior mechanical properties. Their remarkable phase stability, insensitivity to thermal history, and dependence on solution strengthening mechanisms, in sharp contrast to conventional alloys like steels, makes them ideally suited for processing via additive manufacturing (AM). In sectors such as aerospace, automotive, and power generation, a great deal of effort is dedicated to developing high-performance alloys that can withstand increasingly harsh operating conditions. Surface-based deformation techniques were performed on an AM AlMoNbTaTiZr specimen to rapidly elucidate mechanical properties such as hardness, toughness, and strain rate sensitivity. Characterization of both as-deposited and deformed microstructure was performed using transmission-electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDX). We present results of experimental testing and characterization and make comparisons to reported properties of other MPEAs from literature. We show that this MPEA possesses one of the highest reported strength to weight ratios of any alloy. |
