TEM characterization and synthesis of nanoparticle B4C by high-energy milling

Abstract

In this study, nanoparticle B4C synthesis was carried out by high-energy milling. For this purpose, B2O3-C-Mg triple systems were used in the reaction stoichiometric ratios as starting materials in the experimental studies. The reduction process of B2O3 was performed using speks type milling device. The transformation of the ceramic phase of the nanoparticle B4C by XRD analysis was examined. In terms of microstructural characterization of its powder shape and morphology, TEM (imaging and selected area diffraction pattern) investigations were conducted. The product synthesized by the leaching process was cleaned from MgO/B4C impurities and the production of the nanoparticle B4C was performed. After leaching processes, it was determined that some of the synthesized powders were below 50 nm, while others varied between the ranges of 50-350 nm. In TEM examinations of B4C particles carried out after leaching process, it was seen that there were twin formations observed as planar error. Depending on the d values calculated by solving the TEM diffraction patterns, the planes represented by nano-sized B4C particles were determined. © 2019, Advanced Researches and Engineering Journal (IAREJ) and the Author(s).

Structural evolution of mechanically alloyed ODS steel powders during ball milling and subsequent annealing treatment

“…The most diverse feature that differentiate ODS steels from other structural systems is that they have fine dispersoids comprising of several oxide based structures such as Al2O3, Y2O3, Ce2O3 or uniformly dispersed Y-Al-O, Y-Ti-O constituents at a high number density in the matrix [7,8]. These nanoscale particles throughout the matrix, cause the secondary phase particles to prevent the movement of dislocations during deformation and resultant an increment of the density of dislocations in the material [9,10].…”

Influence of ball milling parameters on microstructure and magnetic properties of aluminum bronze chips reinforced with vanadium carbide

“…Also introduces energy into the material being processed through collisions between balls, powders, and the wall of the vial, causing severe plastic deformation, repeated fracturing, and cold welding of the particles resulting in micro and nanometric powders. Thus, by vibration and rotation processes, balls collide inside the vial, pressing the powders at each impact, and through an intense cyclic process of energy transfer with simultaneous action between friction, abrasion, and compression, the resulting particles exhibit different morphologies with reducing sizes [21][22][23].…”
