Gas and Vacuum Carburizing
The solution algorithm used in CarbTool is based on the finite difference method (FDM), and the code is developed using Microsoft Visual C++ in Window OS. The tool has been built on the concept of the carbon flux at the surface between the gas and steel is to be specified by the user. The outputs of CarbTool are the carbon concentration distribution profile inside the steel part and the surfa...
متن کاملModeling of acetylene pyrolysis under steel vacuum carburizing conditions in a tubular flow reactor.
In the present work, the pyrolysis of acetylene was studied under steel vacuum carburizing conditions in a tubular flow reactor. The pyrolysis temperature ranged from 650 degrees C to 1050 degrees C. The partial pressure of acetylene in the feed mixture was 10 and 20 mbar, respectively, while the rest of the mixture consisted of nitrogen. The total pressure of the mixture was 1.6 bar. A kinetic...
متن کاملFailure characteristics of a dual-phase steel sheet
Failure in ductile sheet metal structures is usually caused by one, or a combination of, ductile tensile fractures, ductile shear fractures or localised instability. In this paper the failure characteristics of the high strength steel Docol 600DP are explored. The study includes both experimental and numerical sections. In the experimental sections, the fracture surface of the sheet subjected t...
متن کاملImprovement of Mechanical Properties and Work-Hardening Behavior of Intercritically Annealed Dual Phase Steel
The effect of the initial microstructure and intercritical annealing on mechanical properties and work-hardening response of a high-formability low carbon steel were studied. The work-hardening analysis was based on the modified Crussard–Jaoul method. The ferritic-pearlitic sheets showed low strength and high total elongation with the appearance of the yield point phenomenon. The occurrence of ...
متن کاملGrain Refinement of Dual Phase Steel via Tempering of Cold-Rolled Martensite
A microstructure consisting of ultrafine grained (UFG) ferrite with average grain size of ~ 0.7 µm and dispersed nano-sized carbides was produced by cold-rolling and tempering of the martensite starting microstructure in a low carbon steel. Subsequently, fine grained dual phase (DP) steel consisting of equiaxed ferrite grains with average size of ~ 5 µm and martensite islands with average size ...
