摘要
The invention relates to the field of controlling the physical and mechanical properties of the method of acoustic emission (AE) and can be used in powder metallurgy to control the physical properties of sintered bodies. The purpose of the invention - provision of control of the cutting density mineral ceramics. A method of acoustic monitoring of physico-mechanical properties of products includes nagruzhe- controlled plates pyramidal indenter (Vickers pyramid), the reception apparatus using a standard AE signals arising from the loading and holding (Yobsch) during unloading and outlet indento- pa of the test material (Npaarp ), the density ratio of the number of control signals recorded on the test and the reference product.
