Micro-structures and mechanical properties of Nb/Re layered composite produced by CVD

► It was the first time to research the Nb/Re layered composites produced by CVD. ► The thickness of the phase χ has a profound effect on mechanical properties of Nb/Re composites. ► The mechanical properties of Nb/20 vol.%Re composites with phase χ of 1.4 μm thickness are optimum.
