In order to decrease the difficulty of cold workability and study recrystallization behavior high-grade non-oriented silicon steel, Si content normalization temperature were optimized simultaneously. The microstructure texture both hot-rolled sheet normalized annealing presented a gradient distribution. With in from 3.02% 2.54% increase 850 °C 920 °C, Goss ({110}<001>) intensity at surfac...

in the present study, the influence of annealing temperature on mechanical properties and the microstructure of a high manganese austenitic steel (fe-30mn-4al-4si-0.5c) was investigated. x-ray diffractometry, optical and scanning electron microscopy, hardness and tensile tests were used to analyze the relationship between mechanical properties and microstructure after annealing process. the res...

Oriented silicon steel is vital for power transformer cores, while the high-temperature annealing process limits industrialization of environmentally friendly coatings on surface. In this paper, binders Al(H2PO4)3 solution and silica sol were introduced innovatively. They condensed into macromolecular polymer chains, network structures SiO2 particles at high temperatures, providing stability ad...

In the present work, lubrication properties (friction and wear) of a synthetic ester oil, tris(2-ethylhexyl) trimellitate (TOTM) containing ferrite nanoparticles coated with oleic acid (F3O4-OA) were investigated for two different material pairs: steel ball-steel disc silicon nitride disc. Thus, four TOTM nanolubricants formulated: + 0.010 wt% Fe3O4-OA, 0.015 0.020 Fe3O4-OA 0.025 showing all th...

Silicon is an attractive alloy-type anode material because of its highest known capacity (4200 mAh/g). However, lithium insertion into and extraction from silicon are accompanied by a huge volume change, up to 300%, which induces a strong strain on silicon and causes pulverization and rapid capacity fading due to the loss of the electrical contact between part of silicon and current collector. ...
