METHOD AND DEVICE FOR DETERMINING DURABILITY OF MATERIALS Russian patent published in 2008 - IPC G01N3/12 G01N3/18 

FIELD: testing engineering.

SUBSTANCE: method comprises mounting the flat specimen along the ring contour in the joining-sealing device, maintaining the specimen at a given temperature in the chamber separated into pressure and working chamber by means of the joining-sealing device provided with the specimen, loading the specimen by the pressure of liquid or gas that is inert with respect to the material to be tested from the side of the pressure chamber, exposing the specimen to the corrosion fluid from the side of the working chamber, measuring time period it takes for the specimen to be distorted for given temperature and stress in the specimen and fluid pressure in the pressure chamber, and calculating the durability from the data obtained. The device for realization of the method is proposed.

EFFECT: enhanced reliability.
