Fundamentals of Carbon Steel Part 2

Heat Treatment Cycles – With regard to heat treatment cycles, carbon steels are generally supplied in one of three heat-treated conditions: 1) Annealed Condition – When it is specified that a component is to be supplied in the annealed condition, this normally implies that the steel is to be fully annealed.

It follows from data in figs3 and 4 that the temperature range for high-temperature treatment from 1270C to ~1500C from carbon-carbon composites of the composition and structure indicated has a range of steady-state condition. A composite in this condition may have commercial value if its operating temperature does not exceed the upper level of this range. On the basis of data in Figs 1

High-resolution transmission electron microscopy (HRTEM) has been used in this work to study the microstructural (structure and microtexture) changes occurring during the high-temperature treatment of the unburned carbon concentrates from coal combustion fly ashes. Emphasis was placed on two aspects: (i) the development of graphitic carbon structures and (ii) the disordered carbon forms

Carbon spheres prepared via solvent

Carbon spheres with size of 50–300 nm were synthesized via a solvent-thermal reaction with calcium carbide and chloroform as reactants in a sealed autoclave. The morphologies and microstructures of carbon spheres before and after high temperature treatment (HTT) were characterized by X-ray diffractometry (XRD), scanning electronic microscopy (SEM), energy diffraction spectroscopy (EDS),

Reinforced carbon–carbon

Carbon fibre reinforced carbon (CFRC), carbon–carbon (C/C), or reinforced carbon–carbon (RCC) is a composite material consisting of carbon fiber reinforcement in a matrix of graphite.It was developed for the reentry vehicles of intercontinental ballistic missiles, and is most widely known as the material for the nose cone and wing leading edges of the Space Shuttle orbiter.

Effects of high temperature treatment of carbon

Thermal treatment of carbon nanotubes (CNTs) can significantly improve their mechanical, electrical and thermal properties due to reduced defects and increased crystallinity. In this work we investigate the effect of annealing at 3000 C of vertically aligned CNT arrays synthesized by chemical vapor deposition (CVD) on graphite. Raman measurements show a drastically reduced amount of defects

C/C composite is a carbon-carbon composite material reinforced by high strength carbon fiber for improving mechanical strength and thermal shock resistance. C/C composite is a high-strength lightweight material suitable for heat treatment trays. C/C composite's density is only 1/5 of steel, so C/C trays are much easier to handle.
