When Hadfield manganese steel in the single-phase austenitic condition was strained in tension, in the temperature range - 25 to 300 °C, it exhibited jerky (serrated) flow, a negative (inverse) strain-rate dependence of flow stress and high work hardening, characteristic of dynamic strain aging. The strain rate-temperature regime of jerky flow was determined and the apparent activation energies for the appearance and disappearance of serrations were found to be 104 kJ/mol and 146 kJ/mol… 
Dynamic Strain Aging and Serration Behavior of Three High-Manganese Austenitic Steels
The strain-rate dependence of the flow stress of three high-manganese austenitic steels with different compositions was studied in terms of dynamic strain aging and serration behavior at room
Strain Hardening of Hadfield Manganese Steel
The plastic flow behavior of Hadfield manganese steel in uniaxial tension and compression is shown to be greatly influenced by transformation plasticity phenomena. Changes in the stress-strain (σ−ε)
Twin-Induced Plasticity of an ECAP-Processed TWIP Steel
The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult. Up
Dynamic Strain Aging Phenomena and Tensile Response of Medium-Mn TRIP Steel
Dynamic strain aging (DSA) and rapid work hardening are typical behaviors observed in medium-Mn transformation-induced plasticity (TRIP) steel. Three alloys with manganese ranging from 10.2 to 13.8


Serrated flow in austenitic state of 300 grade marageing steel
AbstractSerrated flow in the austenitic state of 300 grade commercial marageing steel has been investigated in the strain rate range from 4.17 × 10−5 to 1.67 × 10−2 S−1 and at temperatures between

The Effect of Hydrogen on the Deformation and Fracture of Polycrystalline Nickel
AbstractPolycrystalline nickel (grain size 140 μm) containing 9 ppm hydrogen has been mechanically tested over the range − 196 to + 100° C (77 to 373K) and at strain rates from 0·1 to 0·0001 s−1. The
Dislocation Theory of Yielding and Strain Ageing of Iron
A theory of yielding and strain ageing of iron, based on the segregation of carbon atoms to form atmospheres round dislocations, is developed. The form of an atmosphere is discussed and the force
