Bulk Ultrasonic Treatment of Crystalline Materials

چکیده
Ultrasound is widely used in the treatment of materials. Its applications melt processing, surface hardening or finishing, metal forming, welding, etc., are well known and have been reviewed numerous review articles books. Among ultrasound-assisted processes, direct action ultrasonic waves on structure properties bulk materials special interest. Ultrasonic induce oscillating shear stresses which exert mechanical forces crystal lattice defects, primarily dislocations, can yield a number interesting effects crystals. The present paper aims to studies (UST) crystalline First, methods for excitation standing samples analyzed. Then, early effect UST dislocation phase composition, hardness strength with different initial structures An emphasis then made influence advanced ultrafine-grained (UFG) metals alloys processed by severe plastic deformation (SPD). results simulations ultrasound’s atomic molecular dynamics also reviewed.

Predictive analytics for crystalline materials: bulk modulus
The bulk modulus is one of the important parameters for designing advanced high-performance and thermoelectric materials. The current work is the first attempt to develop a generalized model for forecasting bulk moduli of various types of crystalline materials, based on ensemble predictive learning using a unique set of attributes. The attributes used are a combination of experimentally measure...
متن کاملPhase transitions in crystalline materials
We reviewed structural phase transitions in crystalline materials, especially recent simulations and experiments on the shock-induced transitions in iron. They both confirmed a phase transition wave in the picosecond to nanosecond time scale, inferred previously from wave profile analyses. The nonequilibrium molecular dynamics simulation suggests modification of pair potentials from temperature...
