Abstract

Under the attack of irradiation on metallic alloys the following effects are observed: low temperature and high temperature creep and fracture, irradiation aging and embrittlement. According to experiments the time to fracture of metallic alloys decreases many times depending on temperature, irradiation dose and aging. These effects are investigated integrally in the framework of the mechanic of materials methods. To formulate the creep fracture law the energy conservation law is applied. The theoretical curves of creep and creep fracture for different values of irradiation dose are constructed and compared with the corresponding experimental results.
