Abstract

The task of stage-by-stage control by properties of powders material with components Ni-Cr- Al-Y2O3 is considered. The control is based on results measuring of speed elastic waves. A task arises up in powder metallurgy at working off technology of new materials creation. The adequate reflection of dynamics of material properties change with the use of ultrasonic methods is complicated by the change of measuring conditions from the stage to the stage and that is why needs stage-by-stage adaptation of control methods to these changes. The decision of such task is not described in literature. The analysis of conformities to law of forming and change of the acoustic field is conducted on the different stages of influence on the material put acoustic experiment and the dynamics of changes of different speeds waves distribution is investigational in the process of forming of material. Efficiency of the complex use of different speeds waves distribution is shown for the decision of this task.
