Rules of plastic strain-induced phase transformations and nanostructure evolution under high-pressure and severe plastic flow

Autor: Lin, Feng, Levitas, Valery, Pandey, Krishan, Yesudhas, Sorb, Park, Changyong

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 anvil cell (DAC). Crystallite size and dislocation density of Zr are getti

In-situ study of rules of nanostructure evolution, severe plastic deformations, and friction under high pressure

Autor: Lin, Feng, Levitas, Valery I., Pandey, Krishan K., Yesudhas, Sorb, Park, Changyong

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 equal to yield strength in shear and perform the first in-situ study of

Rough diamond anvils: Steady microstructure, yield surface, and transformation kinetics in Zr

Autor: Lin, Feng, Levitas, Valery, Pandey, Krishan, Yesudhas, Sorb, Park, Changyong

Study of the plastic flow and strain-induced phase transformations (PTs) under high pressure with diamond anvils is important for material and geophysics. We introduce rough diamond anvils and apply them to Zr, which drastically change the plastic fl
