Rules of plastic strain-induced phase transformations and nanostructure evolution under high-pressure and severe plastic flow
Feng Lin, Valery Levitas, Krishan Pandey +2
Rough diamond anvils (rough-DA) are introduced to intensify all occurring processes during an in-situ study of heterogeneous compression of strongly pre-deformed Zr in diamond anvi…
In-situ study of rules of nanostructure evolution, severe plastic deformations, and friction under high pressure
Feng Lin, Valery I. Levitas, Krishan K. Pandey +2
Severe plastic deformations under high pressure are used to produce nanostructured materials but were studied ex-situ. We introduce rough diamond anvils to reach maximum friction e…
Multiferroic CuCrO2 under High Pressure: In-Situ X-Ray Diffraction and Raman Spectroscopic Studies
Alka B. Garg, A. K. Mishra, K. K. Pandey +1
The compression behavior of delafossite compound CuCrO2 has been investigated by in-situ x-ray diffraction and Raman spectroscopic measurements upto 23.2 and 34 GPa respectively. X…
Reinvestigation of high pressure polymorphism in Hafnium metal
K. K. Pandey, Jyoti Gyanchandani, M. Somayazulu +3
There has been a recent controversy about the high pressure polymorphism of Hafnium (Hf). Unlike, the earlier known α ω structural transition at 38 8 GPa, Hrubi…
Memory effect under pressure in low density amorphous silicon
Nandini Garg, K. K. Pandey, K. V. Shanavas +2
Our investigations on porous Si show that on increase of pressure it undergoes crystalline phase transitions instead of pressure induced amorphization - claimed earlier, and the am…
