Effects of thermochemical treatment in molten alkali metals on the mechanical properties of refractory metals and alloys

Studies have been made on how borosilicide coatings and individual chemical treatment stages affect the mechanical properties of the substrate metal (unalloyed vanadium and VTsU alloy). The redistribution of interstitial impurities between the liquid and solid metals reduces the plasticity of vanadium and VTsU. The working characteristics can be restored by heat treatment of the coated material, namely high-temperature ageing.
