Why Choose

Why Choose Thermo-Calc?

For more than 40 years, Thermo-Calc Software has been at the forefront of scientific software and databases for calculations involving thermodynamics, phase equilibria, and diffusion-controlled transformations.

Data from these calculations can help you improve your products, optimize processing conditions, decrease time to market, reduce dependence on experiments, and gain a deeper understanding of your materials.

Generate Accurate Computational Materials Data

With Thermo-Calc, users have access to a rich dataset and the tools necessary to extrapolate into the specific composition and processing or operating window of interest on-demand. Users can generate data such as thermophysical properties, segregation behavior, nucleation and precipitation behavior, and use this data to augment their understanding of a material. This is far superior to the traditional methods many rely on of using nominal or average compositions to make assumptions about a class of material or scouring the web and searching for papers that contain specific information for a specific material composition or chemistry only to find, in most cases, that it doesn’t exist. Using computational materials science, Thermo-Calc allows you to generate accurate, reliable materials data when you need it.

Accelerate Time to Market

The data generated from Thermo-Calc can greatly reduce the number of experiments required to bring a new or improved product to market. For example, Thermo-Calc can assist in pre-screening test conditions, enabling you to better target your experiments to get the data you need. By narrowing your parameters and reducing the number of experiments, you can greatly improve time to market.

If you work in a segment of manufacturing where the demand on quality and certification is especially high, carefully constructed test and approval routines are necessary. Thermo-Calc can give you starting points and indications on what is, or is not, worth pursuing. This can greatly improve time to market.

Reduce Costs with Computational Materials Science

Decreasing the number of experiments dramatically reduces the cost of designing and optimizing materials. But cost savings go far beyond experiments. Thermo-Calc can also be used to optimize processing conditions, saving you money on wasted materials, unsuccessful runs, and more.

Improve Materials and Processing Conditions

Thermo-Calc is used extensively in manufacturing to understand how changes in processing conditions affect the final results of your product. By understanding the alloys and how their phase make-up depends on temperature, you can improve the properties of your material or understand why things go wrong in production. Slight adjustments in alloys or process parameters can greatly improve the quality of your final product.

Analyze Breaks in Production Chains

Thermo-Calc is also helpful when analyzing breaks in production chains. Thermodynamic calculations help to identify why, where, and when the break occurs. An example of this is a manufacturer who develops gearboxes for the car industry. Gearboxes use different kinds of steel, all with specific requirements. A manufacturer must know how the cogwheels will react and sustain. When a manufacturer orders steel from a supplier, it is often the case that they will not get the exact alloy, since steel seldom comes in the exact composition. With Thermo-Calc calculations, it is possible to identify the small range of precise chemical components needed to get the steel for cogwheels perfect for the required quality.

The same applies for manufacturers using or developing nickel superalloys, aluminum alloys, and other light metals such as titanium alloys and copper alloys.

Improve Environmental and Ethical Conditions

Many alloys include elements that are crucial for product performance, but have detrimental effects on the environment and health and well-being of those who interact with the materials. Computational materials science can be used to investigate alternative compositions that can reduce or eliminate harmful materials. Read a publication in which Thermo-Calc was used to investigate the substitution of cobalt and another in which Thermo-Calc was used to advance the search for Pb-free solder designs.
