Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Fatigue and creep crack propagation in 20 and 25% cold-worked Type 304 and 20% cold-worked Type 316 stainless steels were examined at 427 to 593°C (800 to 1100°F). The resistance to fatigue crack growth was slightly better for Type 304 stainless steel compared to Type 316 stainless steel, and was improved by an increase in cold work; however, these differences were small Compared to solution-annealed stainless steel, the cold-worked steels had higher crack growth resistance at high stress intensity levels. Creep crack growth occurred at 482°C (900°F), but much higher stress intensities, K, were required than in fatigue. However, at 593°C creep and fatigue crack growth occurred over the same K range and, in fact, at higher K levels crack growth in creep was faster than in fatigue. Retardation of crack growth was observed when the load on a specimen was changed from cyclic to static.
