【 摘 要 】

This paper is devoted to the study of the nickel-chromium alloy G-35, which was intended for the manufacture of a chemical reactor vessel operating in molten chlorides in the temperature range of 550-650°C. A preliminary study of the structure and mechanical properties of the G-35 alloy was carried out in order to select the methods for their investigation. With the help of Photometric analysis of structural images it was found that the weld metal is in the austenitic state and the presence of an alloying of boron was also established. A class of functions has been established that describes the loading curves for three-point bending of samples.
