Abstract:
Transmission and scanning electron microscopy have been used to investigate the structure of molybdenum after complex processing: deformation and irradiation with accelerated argon ion beams. The analysis of the effect of deformation and radiation parameters on the structural transformations and mechanical properties of molybdenum allowed us to find the optimal mode of processing to form a submicrograin uniform-in-size structure.
Keywords:high pressure torsion  irradiation  molybdenum  structure
