Description

Highlights: • CF3, CF3M, CF8, and CF8M CASS have large reduction in adsorbed impact energy after thermal aging. • Strength and ductility undergo minor reduction after thermal aging. • Microstructural changes include spinodal decomposition of ferrite, G-phase precipitation, and solute segregation. • Microstructural changes are dependent on Mo and C concentration and aging temperature. • Temperature dependent changes and drop in impact energy due to microstructural evolution.
