| Abstract Scope |
There are many studies comparing the room-temperature strength of ordered intermetallic alloys in the ordered and disordered state. In contrast, to the author’s knowledge, there do not appear to have been studies comparing the room-temperature elastic modulus in the two states. Knowing the elastic modulus is important for calculations of the strength. In this presentation, we compare the measured strength and elastic modulus of two b.c.c./ordered b.c.c. (B2) alloys, i.e. CuZn and FeCo, and two f.c.c./ordered f.c.c. (L1<sub>2</sub>) alloys, i.e. Ni<sub>3</sub>Fe and the equiatomic medium entropy alloy FeCoNiV, in the ordered and disordered state. In addition, we have determined the effects of interstitials on the room-temperature yield strength and work-hardening behavior of the alloys in the ordered and disordered states.
