Abstract: The novel methods, apparatus and reworked rotary braking surface product, for example those exhibited on interior cylindrical braking surfaces of a cast iron brake drum, serve to replace manufacturing defects exhibiting residual tensile stresses and outwardly directed tool marks with smooth compressed braking surfaces in a final manufacturing stage. The plastically deformed surface shape with reduced roughness and surface irregularities furthermore presents improved braking strength above the yield point and approaching the ultimate material strength of the base drum material. An ultrasonic transducer drives individual freely moving impact elements of a set at frequencies up to 55 kHz into the braking surface to effect plastic deformation at surface and sub-surface layers. Physically, the small sized ultrasonic transducer is inserted into a drum cylinder and driven by a lathe producing relative motion between the braking surface and the ultrasonically vibrating impact elements scanning only the braking surface in a readily controlled ultrasonic impact machining cycle for attaining specified braking surface performance.

Abstract: Carbon steels of high performance are disclosed that contain a three-phase microstructure consisting of grains of ferrite fused with grains that contain dislocated lath structures in which laths of martensite alternate with thin films of austenite. The microstructure can be formed by a unique method of austenization followed by multi-phase cooling in a manner that avoids bainite and pearlite formation and precipitation at phase interfaces. The desired microstructure can be obtained by casting, heat treatment, on-line rolling, forging, and other common metallurgical processing procedures, and yields superior combinations of mechanical and corrosion properties.
