DEVICE FOR STRETCHING TEST OF BOW-SHAPED SAMPLES FROM CONDUCTING MATERIAL AT INCREASED TEMPERATURE Russian patent published in 2015 - IPC G01N3/18 

FIELD: electricity.

SUBSTANCE: device is implemented in the form of composite circular guide, formed by two fragments, rotatable with reference to general axis. Their bearing surfaces coincide by the shape with concave surface of the sample and coaxial hinged shanks connected to the loading device. The bearing surface of both fragments of the circular guide in places of contact with the sample is made of non-conducting and heat-insulating material, mechanisms for sample fastening are implemented in the form of current lead, while, at least, one of them electrically is isolated from device fragments. The device comprises the force, deformation, sample temperature sensors, the power source and the switching device, and also the tight enclosing working chamber fitted with current leads of the power electric circuit for sample heating and with the electrically insulated socket for connection of the force, deformation, sample temperature sensors.

EFFECT: possibility of accurate determination of mechanical properties of bow-shaped samples from conducting materials at monoaxial stretching and pulse heating in vacuum or inert medium with simultaneous protection of the personnel and environment from influence of tested materials.
