Abstract:
Changes in the texture as well as mechanical properties of CoNiFeV0.5Mo0.2 medium entropy alloy wire rods during loading-unloading are investigated. The intensity of the recrystallization texture {001}<110> component and fraction of low angle grains increase with the loading-unloading cycles and the alloy strength increases (934 MPa to 1083 MPa) due to dislocation increment in the loading-unloading cycles. The loading modulus (El) and average modulus (Esecant) for a hysteresis loop decrease slightly, whereas the unloading modulus (Eun) increases, the Eun increment of 5-TC-UTand 10-TC-UT are 22 and 137 GPa.
