Abstract Scope |
High Entropy Alloys represent a new class of materials that possess an ideal combination of high strength and ductility and may be candidate materials that can withstand high amounts of damage before failure, under extreme conditions. To this end, a series of shock/spall loading experiments were conducted on an Fe/Cr/Mn/Ni HEA to assess not only its Equation of State (EOS) but also its resistance to nucleate damage and failure. A single stage light gas gun was used to conduct a series of flyer plate symmetric impact experiments coupled with recovery of the samples for post-mortem microstructural analysis to obtain fundamental understanding regarding the damage morphology. Our results show that the measured EOS for this alloy was in reasonable agreement with an estimated Hugoniot. Additionally, the spall strength of these alloys was found to vary between 1.4-1.9 GPa within the same plate but was comparable to other iron based conventional alloys. |
