| Abstract Scope |
The concept of refractory multicomponent system provides an interesting approach in designing novel metallic biomaterial. Multicomponent system consisting of biocompatible elements targeting biomedical applications. In the present work an atomic model of equiatomic TiMoNbZr medium entropy alloy was built using a melting and quick quenching method and mechanical behaviour of the equiatomic alloy under uniaxial compression and tensile loading are further studied using atomistic simulation. The plastic deformation of TiMoNbZr is affected by the motion of dislocation loops. The prismatic dislocation loops inside TiMoNbZr are formed by the dislocations with the Burgers vectors of a/2 [1 1 1]. In addition, elastic constants were calculated at 0 K for bcc TiMoNbZr alloy and validated with DFT results. Results illustrate a superior metallic biomaterial that possess a desirable combination of high strength and low modulus for the application of biomaterials. |
