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.
