Investigation of the strength of thermal transducers

1.	The temperature-time relationship of the allowable mechanical loads of a thermal transducer protection tube was established.
2.	For a preliminary evaluation of the strength of a thermal transducer in relation to service time it is necessary to use the temperature relationship of the modulus of elasticity or of the stress-rupture strength of the materials used.
3.	Failure of the protection tube of a thermal transducer in long high-temperature loading occurs as the result of development of pores primarily at grain boundaries.
