Twinning is the result of identical motions of atoms of a plurality of rows parallel to a twinning plane in the original lattice. The twin plane is a boundary which separates two orierltations that are mirror images of one another. In other words, twinning   ADVERTISEMENTS: In this article we will discuss about: 1.

One of the most common forms of intergrowth is twinning.

Introduction. Twinning is not an uncommon effect in crystallography, although it has long been considered to be one of the most serious potential obstacles to structure determination.

The use of area detectors has much facilitated the detection of twinning and the treatment of diffraction patterns from twinned crystals. Computer software has also now been developed to such an extent that   This book describes behavior of crystalline solids primarily via methods of modern continuum mechanics.

Emphasis is given to geometrically nonlinear descriptions, i.e., finite deformations. Primary topics include anisotropic crystal elasticity, plasticity, and methods for representing effects of defects in the solid on the material's mechanical. This paper recounts recent advances on the atomistic modeling of twinning in body-centered cubic (bcc) and face-centered cubic (fcc) alloy.

Specifically, we have reviewed: (i) the experimental evidence of twinning-dominated deformation in single- and multi-grain microstructures, (ii) calculation of generalized planar fault energy (GPFE) landscapes, and (iii) the prediction of critical friction The high strain hardening of the C alloy was due to a rapid phase transformation rate from γ-austenite to ε-martensite.

The austenite of C steel was strengthened by mechanical twinning during loading process, and the twinning-induced plasticity (TWIP) effect resulted in a large ://This book describes behavior of crystalline solids primarily via methods of modern continuum mechanics.
