The oxidation behavior of silicon-containing steel was studied by applying segmented heating routes similar to the atmosphere and heating process in an industrial reheating furnace. The oxidation tests were carried out on a simultaneous thermal analyzer at heating temperatures of 1150 ̋C–1300 ̋C. The morphologies of Fe2SiO4 were observed by SEM, and the penetration depths of the Fe2SiO4 layer a...

The loss of biological activity of phage λ DNA was much greater when the DNA was sheared using a ceramic-coated needle attached to a syringe compared with a conventional stainless steel needle. Inactivation of the biological activity was due to breakage at the middle of the molecule. The thickness of the ceramic-coating was a crucial factor for the breakage. Because approximately the same level...

Bainitic microstructures obtained in high-carbon (HC) and high-silicon (HSi) steels are currently of great interest. Microstructural evolution the bainitic transformation kinetics a cast steel held at 280, 330, 380 °C was analyzed using dilatometry, X-ray diffraction, optical scanning electron microscopy, backscatter diffraction (EBSD). It is shown that heterogeneous distribution silicon (Si), ...
