Molybdenum metal is known for having many attractive properties including high thermal conductivity and low coefficient of thermal expansion. Deformation processing helps to increase strength and hardness of metals; however, it has also been shown that cold working can reduce the ductile-to-brittle transition temperature (DBTT) in certain body centered cubic refractory metals. To improve mechanical characteristics of the material, pure Molybdenum was processed with equal channel angular extrusion (ECAE). Three passes of route-A extrusions (i.e., encapsulated bars were not rotated between passes) were used in this study. The processing temperature ranged from 300oC to 450oC. Miniaturized tensile tests were used to assess the mechanical performance and the results are discussed in terms of material texture and grain refinement.
