摘要
Stability of the structure and mechanical properties of high-strength cryogenic nonmagnetic steels 10Kh19G10N6AM2 and 09Kh19G10N6AM2D2 under long-term thermocycling and multicycle mechanical loading is investigated. The mechanical properties of the steels are determined by measuring the HV hardness and testing for tensile strength and impact bending. The phase compositions and the structures of the steels are studied by dilatometry, magnetometry and x-ray diffractometry after various impacts (thermocycling, fatigue loading, and final testing for determination of mechanical properties).
