Thermochemical Treatments of Carburization: What it is

Simulation of carburization and therefore diffusion of carbon in the metal matrix.

Thermal chemical treatments, such as carburization, carbonitriding, gas nitriding, etc. are specific treatments that make use of the diffusion of solute atoms in solid phase in the metal matrix of the base metal. This is done so as to modify the chemical composition of the superficial layer of the alloys and to give them certain properties, such as hardness, wear resistance, resistance to oxidation and fatigue resistance. This type of treatment is used to absorb an extraneous chemical element, which gives the surface itself high hardness or other properties.

Carburization simulation: How it works

DEFORM simulation software makes it possible to develop models that can be used to determine the most effective heat treatment parameters for a particular application, thus restricting sampling and trials to resolve any problems that could arise during the entire thermal process and thereby avoiding wasting money and time.

For example, regarding the carburization process, which is currently the most widely used diffusion process on an industrial scale, thermochemical treatment simulation includes and models the effects of the process parameters on the depth of the carburized layer, carbon concentration, microstructure, residual stress, distortion and deformation. The software predicts, before going on to sampling, the profile and depth of the carbon enriched layer in case-hardened steels modelling the absorption and diffusion of carbon during the entire thermochemical process.

DEFORM works both on PC and on standard 6, 8 and 12 core workstations, automatically showing defects and problems of the entire process on its whole.

What customers say about DEFORM:

DEFORM carburization simulation software is American and has been optimised to be reliable, quick and easy.

Ecotre Valente from Brescia proposes DEFORM to optimize costs through process simulations
Not only reductions in shiftwork and production in the lower cost ranges, energy savings can also come from a simple one software.
A popular saying goes that "necessity sharpens the wits", meaning that when you are in critical conditions it is a process of nature find new solutions to problems, and in this case to costs.
Precisely in the face of the expensive energy Ecotre Valente, it has decided to offer its customers a new weapon represented by the software DEFORM for the simulation of energy consumption in furnaces...

Modeling the heat treatment of ausferritic ductile iron

28/12/2021

DEFORM

Ausferritic ductile iron (ADI) combines the freedom of the molding style of cast iron with the strengths of steel. ADI forms by heat treatment of nodular cast iron. To take full advantage of the technical potential of this material, extensive controls of the casting and the heat treatment processes are required. The authors describe an integrated approach of experimental studies and modelling for optimum process design. The simulation tools developed permit exact predictions of the microstructure due to the heat treatment. If certain suitable technical parameters are observed, an ausferritic microstructure without pearlite, martensite and bainite can be obtained. The parts produced had very good reproducible mechanical properties distinctly better than the applicable limits

DEFORM

Predicting and managing heat treatment distortion of complex parts is a huge challenge. DEFORM-HT is a powerful tool for simulating heat treatment processes. The system predicts heat treat distortion, residual stresses and phase volume fraction.
Heat treatment modeling helps to achieve hardness and strength requirements while minimizing heat treat distortion and residual stresses.
Kistler-IGeL GmbH, the DEFORM distributor in Germany, worked with Rob. Bosch GmbH, DaimlerChrysler AG, Institute of Material Science and Engineering of Karlsruhe and other partners on a Computer Aided Simulation of Heat Treatment project (CASH), funded by the German Federal Ministry for Education and Research. The objective was to establish a modeling methodology for the heat treatment of complex parts.

Simulation of Induction Hardening – Software DEFORM

DEFORM

The DEFORM™ predicted temperature-time variations at the exit of the coil were very close to those measured via optical pyrometer in the actual process.
Applying boundary conditions to lock one end of the shaft and allow the other end to move freely facilitated the prediction of axial dilatation.
Predictions from DEFORM™-HT can provide designers and metallurgists with valuable information on the scanning induction hardening process. Shaft temperature, case depth, residual stresses and resultant distorted geometry are just some of the results available from simulation.
In addition, induction coil design can be facilitated by the DEFORM™-HT system.

Quench distortion of keyed shaft – Software DEFORM

21/12/2021

DEFORM

Quench distortion during heat treatment is a commonly encountered problem in metal processing industries. It is considered extremely complex and is attributed to material and thermal properties of the workpiece, and quenchant properties. Phase transformations in steels further complicate the phenomenon.
It was observed that during quenching, steel shafts tended to distort more severely if they contained keyways. Non-uniform cooling due to the nonaxisymmetric geometry may have been responsible for inducing the additional distortion.

It is a matter of time. The simulation software for casting, forging, rolling, heat treatment and machining allow to expand or compress it: ingots of tons that take days, to give just one example, can be reduced and evaluated in a few minutes; conversely, steps of a few thousandths can be analyzed in hundreds of seconds. But the time factor today is also the key to the diffusion process of these virtualization programs of the production cycle. "It's only a matter of time: even in the world of steel, the tools that allow the virtual reality of production processes will be widespread."
