Abstract Scope |
A novel high entropy alloy Al0.65CoCrFe2Ni comprising of both FCC and BCC phases is designed, and fabricated through two liquid state techniques. One alloy sample is processed using a vacuum induction melting technique in an industrial-scale melting furnace. The other alloy sample is fabricated in a lab-scale copper suction casting facility having a considerably higher cooling rate of solidification. Split Hopkisnon pressure bar test is carried out under compressive loading at strain rate of ~2000s-1 for both the industrial-scale induction melted alloy and lab-scale suction cast alloy samples. The effect of cooling rate on both alloy samples under high strain rate deformation is analyzed by observing their strain hardening behavior and strain rate sensitivities. The predictability of high strain rate behavior of the high entropy alloy will also be examined using Johnson-Cook modeling. |
