  4. 2. Mechanical Properties of Transition Metal Alloys from First-Principles Theory

    Author : Xiaoqing Li; Levente Vitos; Manuel Richter; KTH; []
    Keywords : ;

    Abstract : The aim of the thesis is to investigate the alloying effect on the mechanical properties of random alloys using the all-electron exact muffin-tin orbitals methodin combination with the coherent-potential approximation. The second-order elastic constants describe the mechanical properties of materials in the small deformation region, where the stress-strain relations arelinear. READ MORE
