Abstract:

The high temperature plastic deformation of refractory metals in vacuum 0.0001-0.00001 torr differ from deformation in air in 1 an absence of scale on the surface of the billets very fine somewhat oxidized layer is formed only on Ti and Nb, 2 an increase for Nb, Mo, and evidently W, and a decrease for Ti of the friction coefficient during rolling, and 3 an increase in the deformation resistance for Mo and W and a decrease tor Ti and Nb during rolling.
