　　A systematic study of mechanical properties of tungsten alloys has been carded out using density function theory calculation.The influence of substitution of transition metal element (TM: Re, Ta,Hf, Os, Ir) on the mechanical properties of crystalline tungsten has been studied.The formation energy, elastic constant and ideal tensile strength in the [001] direction of alloyed tungsten have been calculated.
