  • Deformation heating and melting of solids in high-speed

    A steel ball rapidly spinning round its vertical axis is allowed to fall a short distance and to bounce off an inclined flat solid surface. The friction of steel on various solids in a vacuum of ca . 10 -4 mm Hg at sliding speeds up to 700 m/s is determined from the measured direction of the ball
