Plastic Deformation of Single‐Crystal Diamond Nanopillars
Advances in Materials, 2020Diamond is known to possess a range of extraordinary properties that include exceptional mechanical stability. In this work, it is demonstrated that nanoscale diamond pillars can undergo not only elastic deformation (and brittle fracture), but also a new

Oxidation behavior of CoCrFeMnNi high entropy alloy after plastic deformation
, 2020Oxidation kinetics of the plastically deformed CoCrFeMnNihigh entropy alloy (HEA) conforms to the multi-stage parabolic rate law, and the oxidation kinetics transition is triggered by the recrystallization.

Visco-plastic deformation analysis of rock tunnels based on fractional derivatives
Tunnelling and Underground Space Technology, 2019The squeezing of rock tunnels in soft strata is often encountered during and after excavation, which is closely related to the viscoplasticity of rock mass.

On the Theory of Plastic Deformation
Proceedings of the Physical Society. Section A, 1951A model for plastic deformation in soft metals, i.e. metals which are not age-hardened or severely cold-worked, is given. It is based on the assumption that in real crystals there is always a number of regions present which, by an unknown process, act as sources of dislocations.

On the plastic deformation of superconductors
Journal of Physics F: Metal Physics, 1980In the transition from the normal (n) to the superconducting (s) state the creep rate of metals flowing under constant stress increases while, if deformation occurs at a constant strain-rate, a small drop in the flow stress, △σns, is observed. These “softening” effects have been the subject of an extensive literature in the last few years. The material

Mechanisms of WC plastic deformation in cemented carbide
Materials & Design (1980-2015), 2018The WC-Co cemented carbides with ultracoarse and ultrafine grain structures were tested by the bonded interface technique to investigate the deformation behaviour of WC.

Thennoluminescence in Plastically Deformed KBr
physica status solidi (b), 1963AbstractThe thermoluminescence of plastically deformed KBr crystals is measured in the temparature range 80‐350 °K for differing amounts of deformation. It is found that the glow peaks characteristic of undeformed crystals are greatly enhanced but that no new glow peaks appear.The effect of annealing at different temperatures, before X‐ray excitation ...

Neck Deformities in Plastic Surgery
Facial Plastic Surgery Clinics of North America, 2019This article provides facial plastic surgeons with the insight to avoid and address common pitfalls in neck procedures. Many aesthetic issues are created from overtreatment or undertreatment of components of the neck. Using the platysma muscle as the divide, ease of access to superficial anatomy leads to overtreatment problems, whereas difficulty of ...
