Evolution of Stress Rupture Property for K439B Superalloy During Long-Term Thermal Exposure at 800 °C

Evolution of Stress Rupture Property for K439B Superalloy During Long-Term Thermal Exposure at 800 °C

The K439B superalloy is widely utilized in aeroengine components due to its superior weldability and mechanical performance. Given that the hot-end components of aeroengines typically operate at high temperatures for extended periods, even up to 10,000 h, it is essential to investigate the stress ru...
