Wood’S Alloy

The article examines the process of crystallization of Wood alloy using the ultrasonic method. The dependence of the determination of the speed of sound in three aggregate states of the alloy (liquid, solid, transition (liquid-solid)) was derived. The relation-ship with the amplitude values of the sound signal, a single pulse in determining the speed of sound, as well as in determining the state of the alloy is carried out. The data obtained allow us to analyze the state of the alloy and the measurement time and the specified frequency range directly in the process of crystallization.

A conceptual model consisting of diagrams, text and terminology dictionary, made in a formalized way and representations of functions, each of which reflects the real state of the long-running metal at all stages of the life cycle. Based on the developed conceptual model, analysis of the results of electron microscopic studies measuring the acoustic characteristics and determination of physical and mechanical properties of the complex criterion limiting state long working metal technical devices hazardous production facilities.

A study of the prospects spectral-timbre of the acoustic method for their construction and analysis of disperse systems of layers of soils and soils and in particular the possibility of choice from the offered list of the minimum required number of factors and ranges of their actions for the most reliable identification of the structure of the object according to the accepted classification scale; - determination of the qualitative (elemental) and quantitative ratio of the studied dispersed systems, based on indirect measurement and computer calculation methods. An express analysis of dispersed objects in the form of soil layers and soils on a PC based on a tape recording of an acoustic analog absorption signal is developed.
