The in vitro dissolution of plasma-sprayed hydroxyapatite (PHA) coatings with different characteristics, produced by various spraying conditions, in a Tris-buffered solution at pH 7.4 was experimentally studied through the measurement of calcium ions release with Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), and then modeled. Three coating characteristics, th...

piroxicam has two different crystalline forms (known as needle and cubic forms), that they are different in physicochemical properties such as biological solubility. in the current research, using taguchi experimental design approach the influences of five operating variables on formation of the piroxicam polymorph shapes in recrystallization were studied. the variables include type of solvent,...

Recrystallization, which can occur dynamically or statically, is an importantphenomenon causing microstructure changes in deformed metals and therefore affecting theproperties of the material. Even though extensive investigations have been carried out on thenumerical modeling of recrystallization, the literature lacks accurate recrystallization modelswhich are able to predict mi...

Nucleation of recrystallization in deformed metals is discussed with a focus on how theories have been achieved from experimental investigations. Suggested nucleation mechanisms and potential sites are reviewed to gain an overall understanding the state-of-the-art. Limitations applied techniques followed by analysis newly invented non-destructive 3D challenged accepted which based 2D studies. F...

Distance function-based diffusion generated motion, a highly efficient numerical algorithm, is used to simulate a classical model of recrystallization in unprecedented detail and in physically relevant parameter regimes not attainable with many previous techniques. The algorithm represents interfaces implicitly and is closely related to the level set method. In particular, it allows for automat...

a review on the microstructural evolution in magnesium alloys during severe plastic deformation waspresented. the challenges deserved to achieve ultrafine/ nanostructured magnesium were discussed.the characteristics of the processed materials are influenced by three main factors, including i)difficult processing at low temperatures, ii) high temperature processing and the occurrence ofdynamic r...
