Mechanical properties of ternary molybdenum–rhenium alloys at room temperature and 1700 K
Molybdenum–rhenium alloys have a lower ductile-to-brittle transition temperature than molybdenum, which is advantageous in applications requiring improved room temperature ductility or impact toughness. However, at high temperatures rhenium strengthens molybdenum only slightly. This work screens the...

| description | Molybdenum–rhenium alloys have a lower ductile-to-brittle transition temperature than molybdenum, which is advantageous in applications requiring improved room temperature ductility or impact toughness. However, at high temperatures rhenium strengthens molybdenum only slightly. This work screens the effect of alloying additions of Ti, Nb, Ta, and Hf on the room temperature ductility and high temperature strength of Mo–26 at.% Re (Mo–40.5
wt.% Re). Hafnium is found to be a particularly effective high temperature strengthener. |
