... steelmaking techniques can reduce the inclusions to negligible levels. It is beneficial to machinability to avoid hard inclusions. However, certain inclusions are plastic and act as solid-state lubricants and chip breakers and prevent adhesion of the material to the tool. The beneficial effect of controlled...

... on the basis of cavitation erosion resistance. One of the more commonly used techniques is the vibratory (ultrasonic) system, which consists of an ultrasonic horn that is partly submerged in the liquid, which is contained in a breaker ( Fig. 5 ). The vibration, typically at 20 kHz frequency, generates negative...
