and quenching with carbonization or induction. The code "HEARTS" for 3-D simulation of heat treatment process based on a metallo-thermo-mechanical theory is presented. Coupled equations of heat conduction, inelastic stresses and kinetics of phase transformations are derived as well as the diffusion equation during carbonization, followed by finite element formulation. The program is available......
Preparation of Cyclodextrin-Based Carbonaceous Catalyst and Its Application in the Esterification单纯Department of Environmental and Chemical Engineering,Shanghai UniversityDepartment of Automation Science,Guangdong Polytechnic Normal University摘 要:A new carbonaceous catalyst with sulfonic acid group (-SO3H) was prepared by incomplete carbonization of β......
chemical precipitation method.Magnetite/carbon nanocomposite thin films were subsequently formed upon carbonization of the starch component by heat treatment under controlled conditions.The initial content......
after carbonization and densification. The microstructural characteristics of samples were investigated by scanning electron microscopy(SEM), X-ray diffraction(XRD), and Fourier-transform infrared(FT-IR) spectroscopy. The results indicate that the density of both the walnut and white poplar is increased, and the open porosity is decreased with the increasing number of carbonization cycles. The XRD......

The compressive strength of composites increases by 22% after successive carbonization process, but the impact toughness decreases slightly, and the fracture model......
of MoSi2. The major carbonization productions are Mo5Si3C and Mo2C. The structure of carbonized layer is loose and there is a large number of circular holes with thickness of about 500-800 μm... phase diagram. The content of Mo2C gradually increases from inner to extra of the sample. The carbonized products form from carbonizing Mo5Si3, rather than a direct carbonization product of MoSi2......
