The Portevin-Le Chatelier effect in the Continuous Time Random Walk framework
A. Sarkar, P. Barat
We present a continuous time random walk model for the Portevin-Le Chatelier (PLC) effect. From our result it is shown that the dynamics of the PLC band can be explained in terms o…
Scaling Behaviour and Complexity of the Portevin-Le Chatelier Effect
A. Sarkar, P. Barat
The plastic deformation of dilute alloys is often accompanied by plastic instabilities due to dynamic strain aging and dislocation interaction. The repeated breakaway of dislocatio…
Effect of heavy ion irradiation on microstructure and electron density distribution of zirconium alloy characterised by X-ray diffraction technique
A. Sarkar, P. Mukherjee, P. Barat
Different techniques of the X-ray Diffraction Line Profile Analysis (XRDLPA) have been used to assess the microstructure of the irradiated Zr-1.0%Nb-1.0%Sn-0.1%Fe alloy. The domain…
Multiscale Entropy Analysis of the Portevin-Le Chatelier Effect in an Al-2.5%Mg Alloy
A. Sarkar, P. Barat, P. Mukherjee
The complexity of the Portevin-Le Chatelier effect in Al-2.5%Mg polycrystalline samples subjected to uniaxial tensile tests is quantified. Multiscale entropy analysis is carried ou…
Scaling Behavior of Portevin-Le Chatelier Effect
A. Sarkar, P. Barat, P. Mukherjee +1
The scaling behavior of the Portevin-Le Chatelier (PLC) effect is studied by deforming a substitutional alloy, Al-2.5%Mg and an interstitial alloy, low carbon steel (0.15%C, 0.33%M…
Portevin-Le Chatelier Effect: a Poisson Process
P. Barat, A. Sarkar, Arnab Barat
The Portevin-Le Chatelier (PLC) effect is a kind of plastic instability observed in many dilute alloys when deformed at certain ranges of strain rate and temperature. In this lette…
