Character of the Dislocation Bands in the (A+B) regime of the Portevin-Le Chatelier effect in Al-2.5%Mg alloy
A. Chatterjee, A. Sarkar, P. Barat +2
The Portevin-Le Chatelier(PLC) effect has been investigated by deforming Al-2.5%Mg alloy in the strain rate regime where simultaneously two types (type B and type A) of serrations…
Rietveld refinement of ZrSiO4: application of a phenomenological model of anisotropic peak width
A. Sarkar, P. Mukherjee, P. Barat
The anisotropic broadening of ZrSiO4 sample is modelled using the Stephens's phenomenological model for anisotropic line broadening and the three dimensional strain distribution in…
Characterization of irradiated microstructure by X-ray diffraction line profile analysis
A. Sarkar, P. Mukherjee, P. Barat
Zirconium based alloys have been irradiated with 11 and 15 MeV proton and 116 MeV oxygen ions at different doses. The changes in the microstructure have been studied for the ion ir…
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…
