| Abstract Scope |
A promising suitable alternative to nickel super alloys is the use of refractory metals. Among the high temperature refractory metals, molybdenum (Mo) is an attractive candidate due to its significantly lower density than the others refractory metals. A systematic experimental investigation of the room-temperature mechanical response of polycrystalline commercially molybdenum (Mo) alloy is presented. Tensile tests have been performed to investigate the anisotropic behavior of such alloys. Using Digital image correlation measurements, the evolutions in the plane of the plate of the yield stresses, the Lankford’s coefficients are determined for a cold rolled Mo alloy. Results reveal that the mechanical behavior is anisotropic in yield stress, r-values as well as in fracture strain. The results obtained for the Mo alloy are discussed in comparison with the mechanical behavior of a pure polycrystalline Mo materials that have been characterized in a previous study. |
