GEAR FOR TEST OF MATERIALS Russian patent published in 2000 - IPC

FIELD: determination of physical and mechanical characteristics of materials, specifically, micromechanical test of materials with coats and tool materials. SUBSTANCE: gear for test of materials includes base with pendulum coupled to it, unit loading material with indenter, system recording test results, protractor measuring deviation of pendulum, mechanism registering position of pendulum, system of heating and cooling of samples, system recording acoustic emission and mechanism controlling linear movement of tested surface of sample. Achieved technical result of invention lies in possibility of loading of local volumes of material with recording of results of destruction of material at microlevels by parameters of acoustic emission. EFFECT: increased accuracy of obtained information on properties of material, improved informativity of recorded parameters of destruction of material. 6 cl, 8 dwg
