The utilization of carburizing materials in engineering fields has undergone so many tremendous changes in engineering fields. Gas carburizing is one of the surface engineering techniques widely used in the process of heat treatment in all the engineering industries. Carburizing is a complex process; it involves a number of variables for the success of the carburizing process. Effective quality...

Propane has been pyrolyzed in a flow reactor system at different temperatures ranging from 640 C to 1010 C and at 8 mbar of partial pressure which are typical vacuum carburizing conditions for steel. Nitrogen was used as a carrier gas. The products of pyrolysis were collected and analyzed by gas chromatography. The reactor was numerically simulated by 1D and 2D flow models coupled to a detailed...

      Simulation of metallurgical processes has been the subject of intense research due to the reduced number of experiments required for controlling the process as well as time and energy savings it allows. In gas carburizing of steel parts, the amount of carbon at the surface of carburized parts is the most important specification of the process in terms of achieving the desired metallurgica...

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...

The carbonitriding process, which involves the diffusion of both carbon and nitrogen into the base steel, can be carried out in a salt bath or in a furnace gas atmosphere. It is a modified carburizing process but is mostly done at a lower temperature and for shorter time than carburizing. This process is one of the widely used heat treatments for surface hardening. Nonetheless, there are challe...
