Russian scientists from the Don State Technical University (DSTU) have developed a wave deformation hardening (WDH) technology for welded joints of nuclear reactor vessels. This innovation significantly improves the strength and quality of joints, which is crucial for nuclear power.
The WDH technology provides deep hardening of the most stressed areas of the welded joint, which increases the critical brittle temperature by 30% and improves the strength characteristics by 1.3-1.5 times. This makes welded joints more resistant to damage and critical operating conditions.
In addition, scientists have optimized cutting modes for processing heat-resistant materials used in reactors. This increased the wear resistance of cutting tools by up to 2.5 times and reduced the labor intensity of technological processes for machining parts by 30%. These studies were conducted in collaboration with "AEM-technology" enterprises, which are part of Rosatom's machine-building division.
Thus, the new technology and improved cutting modes will help increase the reliability and service life of nuclear reactors, as well as improve the efficiency of production processes.
