beta-type Zirconium alloys are promising biomedical implant materials, the elastic and magnetic properties of which are of great importance to be studied. In this work, beta-type Zr1-xTax binary alloys (x = 0.0625, 0.125, 0.1875, 0.25, 0.3125, 0.375, 0.4375, 0.50, 0.5625, 0.625, 0.6875, 0.75, 0.8125, 0.875, 0.9375) were established. The effects of Ta content on lattice constant, elastic properties and magnetic properties of beta-type Zr-Ta alloys were investigated via first-principles calculations, the calculated results were also verified through experiments. The results shown that with the i...
