Resonance Ultrasonic Spectroscopy of a Nanofibrous Composite and Studying the Effect of Surface/Interface

Resonances are intrinsic characteristics of an elastic object, which are completely independent of the source of excitation. The appropriate utilization of the information contained within the resonance spectra and the identification of the resonance frequencies of the object can be used as a potent tool for material characterization. In this paper, a new mathematical model for the wave diffrac...

Effect of Ultrasonic Vibration on the Metallurgical Properties of Steel

Ultrasonic Characterization of Austenitic Stainless Steel in Thermal Variations

This work focuses on the ultrasonic characterization and hardness of Austenitic stainless steel in thermal variation. The sample which was heat treated at 1050 o C has the highest hardness value and plays a dominant role in dispersion of carbides. Shear wave velocity and hardness show similar trend in variation with temperature. The effect of volume expansion would be to decrease the elastic co...

Possibility of Determining Steel Grain Size Using Ultrasonic Waves

The microstructure of steel is decisive for its chemical, physical and mechanical properties. Depending on the parameters characterising liquid metal as well as the parameters of the steel casting influencing the crystallisation process, the macrostructure of casts and ingots consist of three, two or only one crystallisation zone. In steel ingots, its most frequent by consist of three zones: ch...
