摘要: Ultrasonic processing is known to be an efficient means of aluminium melt degassing and structure modification with additional benefits being economical environment friendly. The present paper reports on the kinetics ultrasonic regassing foundry alloys pilot scale trials. Efficiency compared conventional Ar rotary degassing. Direct measurements hydrogen concentration in by Foseco Alspek-H probe are used along reduced pressure test. effects porosity studied using three-dimensional X-ray tomography.
