Determination of the physicomechanical and technological properties of cermet materials on a single annular specimen
- 10 Downloads
A method for testing cermet materials by means of unique annular specimens, specified by GOST 6551-53, has been developed and is successfully used at the powder metallurgy laboratory of the Kuibyshev Institute of Aviation. These specimens can be used for determining the density, the electric resistivity, the hardness, the strength, and the oil absorption ability as well as for investigating the microstructure.
Adapters for testing annular cermet specimens for ultimate strength, and also a contactless method and an instrument for measuring the electric resistivity have been developed.
