Is there an effect of dynamic strain aging on dislocation evolution?
Materials Research LettersHerein, we explore the effect of dynamic strain aging (DSA) on dislocation evolution using nanoindentation and transmission electron microscopy (TEM). DSA is primarily manifested as serrations on the load-displacement curves at lower strain rates (10−2 ...

Journal of Materials Research and Technology, 2021 The present work deals with revealing the fatigue and dwell-fatigue behavior and correlated damage mechanisms of Fe–Mn–Al–C lightweight steel. Surprisingly, alteration in loading mode from monotonic to cyclic induces reversible dislocation movement and ...

Numerical modeling of the dynamic strain aging in steels at high strain rates and high temperatures [PDF]
EPJ Web of Conferences, 2021 Carbon steels can be heat treated to produce different microstructural variations and mechanical properties. At high temperatures the material plasticity and strength can be influenced by diffusional effects like the Portevin-Le Chatelier effect, leading

Dynamic Strain Aging of a High Strength Steel [PDF]
Journal of Basic Engineering, 1967 The response of quenched and tempered, and ausform H-11 steel to strain aging was investigated. The straining temperature was the most important variable. Straining at elevated (up to 900 deg F) temperatures and retempering resulted in large increases (approximately 30 percent) in yield strength without the loss in ductility associated with static ...
