The completed tests convincingly show that the time of strain-hardening of small blades of alloy VT8 by 1.3-mm-diam. balls should be no greater than 5 min if the edges are not protected by shields. Such strain-hardening significantly increases the endurance limits of blades with almost no reduction...
