Observations of dynamic strain aging in polycrystalline NiAl [PDF]
Intermetallics, 1996 Abstract Dynamic strain aging has been investigated at temperatures between 77 and 1100 K in eight polycrystalline NiAl alloys. The 0.2% offset yield stress and work hardening rates for these alloys generally decreased with increasing temperature.

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 ...

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 ...

Unveiling the Mechanisms of High-Temperature 1/2[111] Screw Dislocation Glide in Iron–Carbon Alloys
Crystals, 2022 We have developed a self-consistent model for predicting the velocity of 1/2[111] screw dislocation in binary iron–carbon alloys gliding by a high-temperature Peierls mechanism.

Conditions for development dynamic strain steel ageing
Science and Transport Progress, 2011 Contrary to the one-sided straining, after compressive predeformation with subsequent tension the shift of appearing the first stress stall to higher values of strains can be observed. The values of compressive predeformation and the strain of first stress stall appearance are approximately equal.

Journal of Materials Research and Technology, 2018 The development of dislocation structures associated with work hardening stages and dynamic strain aging (DSA) is investigated in an AISI 301 austenitic stainless steel plastically deformed in tension at 500 and 600 °C. In the first work hardening stage,
