چکیده
Microstructure is a feature of crystals with multiple symmetry-related energy-minimizing states. Continuum models have been developed explaining mi-crostructure as the mixture of these symmetry-related states on a fine scale to minimize energy. This article is a review of numerical methods and the numerical analysis for the computation of crystalline microstructure.

Computation of Crystalline Microstructure
Microstructure is a feature of crystals with multiple symmetry-related energy-minimizing states. Continuum models have been developed explaining mi-crostructure as the mixture of these symmetry-related states on a ne scale to minimize energy. This article is a review of numerical methods and the numerical analysis for the computation of crystalline microstructure.
متن کاملEffect of Ni content on the reaction behaviors and microstructure of TiB2-TiC/Ni cermets synthesized by MASHS
In this paper TiB2-TiC/Ni cermet with various Ni (20, 40 and 60 wt %) content were synthesized by mechanically activated self-propagating synthesis (MASHS) and effect of the addition of Ni on synthesis parameters and microstructure of synthesized samples were investigated. First raw materials (B4C, Ti and Ni) milled in Ar atmosphere. Then milling powders analyzed by XRD. In next step powders sy...
متن کاملPretreatment Effect on the Properties of Electroless Nano - Crystalline Nickel Phosphorous Coating
the influence of mechanical polishing pre-treatments on steel substrates is investigated in terms of microstructure, deposition rate, adhesion, mechanical and corrosion properties of electroless Ni-P nanocoating with 9-10% wt. of P content. XRD analysis of Ni-P coatings demonstrated the nanocrystalline structure of coating with the grain size of 39 nm. Results showed that pretreatment of substr...
متن کاملSynthesis and Seeding Time Effect on the Inter-Crystalline Structure of Hydroxy-Sodalite Zeolite Membranes by Single Gas (H2 and N2) Permeation
Microporous hydroxy-sodalite zeolite membranes with different morphologies were synthesized via secondary growth technique with vacuum seeding on tubular α-Al2O3 supports at two different synthesis conditions (i.e. two different routes). Microstructures of the synthesized membranes were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM) and si...
متن کاملThe Effect of sintering temperature on microstructure and hardness of milled WC- 20 wt.% equiatomic (Fe,Co) cemented carbides
In this study, WC–20 wt.% equiatomic (Fe,Co) powder mixture was milled in a planetary ball mill. The effects of different milling time (15 min, 5h, 10h, and 25 h) and sintering temperatures on the microstructure and mechanical properties of this equi-Fe substituted cermet were investigated. The structural evolution and the crystallite size changes of the powders during milling were monitored by...
