Strengthening of CoNiFeV 0.5 Mo 0.2 Medium Entropy Alloy Wire Rods with Loading-Unloading Cycles

Changes in the texture as well as mechanical properties of CoNiFeV Mo medium entropy alloy wire rods during loading-unloading are investigated. The intensity of the recrystallization texture {001} 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 (E ) and average modulus (E ) for a hysteresis loop decrease slightly, whereas the unloading modulus (E ) increases, the Eun increment of 5-TC-UTand 10-TC-UT are 22 and 137 GPa.
