Why Choose Thermo-Calc?

Materials research is both time-consuming and expensive. It can take 10 to 20 years from initial research, via testing and qualification, before a new material is incorporated into commercially viable products.

Additionally, many existing materials still have unanswered day-to-day questions that require trial and error-based studies. For example, there are often questions related to processing, composition and quality control, failure analyses, lifetime predictions and understanding how existing materials behave under new operating conditions.

With the speed of technological innovation, and the increased demands placed on materials, it is more important than ever to be able to efficiently develop new materials with specific properties and to optimise existing materials and processing methods. To better address these challenges, materials scientists and engineers are turning to computer simulation to guide their research and development.

Thermo-Calc allows you to make calculations that give you information to make better decisions about your materials and reduce your dependence on experiments and trials. Download a free demo today and see what Thermo-Calc can do for you.

Base Decisions on Scientifically Supported Data

Historically, the materials science and engineering field has relied almost exclusively on experimentation to establish the processing-structure-property relationships of materials. Empirical models were initially developed through trial and observation correlating a property to the experimental conditions. As our understanding through materials science has evolved, semi-empirical and mechanistic models have been derived that are more powerful and more predictive.

Thermo-Calc is based on the CALPHAD approach: a self-consistent, phase-based approach that relates the underlying thermodynamics and phase equilibria of chemical systems by capturing the composition and temperature dependencies. Databases are constructed through a critical evaluation of experimental data (combined with ab initio predictions where needed) of the underlying binary and ternary systems, allowing Thermo-Calc to make predictions for multicomponent systems of interest.

The approach has also been extended to consider the modelling of atomic mobilities that can be used to describe kinetic phenomena, such as diffusion and precipitation.

Molar volume data is also assessed, which can be used to model density and thermal expansion. By combining the thermodynamic and mobility data, predictions can be made in a wide range of areas such as welding, heat treating, corrosion, and alloy production.

 

With Thermo-Calc you can make calculations which predict or assist in the understanding of complex multicomponent alloys and non-metallic systems, allowing you to make better decisions about your materials and processing.

 

Reduce Dependence on Trials

Thermo-Calc does not replace the need for experiments, but it reduces the number required when compared to a trial and error approach. Thermo-Calc can also deepen the insight and understanding of the data that experiments provide, making the results more useful.

For example, Thermo-Calc can assist in pre-screening test conditions, enabling you to better target your experiments to get the data you need. Additionally, some experiments are impractical or impossible to perform, particularly those involving the identification of slow precipitating, life limiting phases that may form during operation. With Thermo-Calc, you can simulate these conditions, and make predictions about material behaviour.

Cited over 12,000 times


Thermo-Calc has long been recognized in the scientific community as a trusted and reliable tool in thermodynamic and kinetic simulation software. Since 1997, Thermo-Calc has been cited over 12,000 times in peer-reviewed publications, not by us, but by scientists and researchers using our software.

Thermo-Calc has also been used in research presented at countless conferences worldwide. In fact, about 1/3 of our customers first heard of Thermo-Calc from a colleague, reading a paper or attending a conference presentation!

Peer review is important to us. The basis of many of our underlying models are published in scientific journals and our database information sheets provide extensive details of the systems that have been evaluated and validation performed so researchers can determine their quality.

Accelerate Innovation While Reducing Costs and Risks


Lengthy development cycles impede how quickly you can bring products to market. When research and development is tied exclusively to physical experiments, innovation is limited by both the time taken to perform the experiments and the budget allowed.

With Thermo-Calc it is possible to explore a larger composition space on a computer than would be possible through experiments only, before even stepping into a lab.

Thermo-Calc can be a valuable tool at all stages of the materials life cycle, and these kinds of approaches are already being used by organisations in a wide range of industries.

Safeguard Specialist Knowledge

Cited in over 1,000 patent applications.

With an ageing workforce in the engineering world, years of materials knowledge and experience is at risk of being lost in many organisations. Often, when a problem arises in production, the senior engineers know just what to tweak to get things back on track, but they might not know the why or how behind it. Thermo-Calc is not only utilised to figure out the ‘why and how’, but as a tool for the next generation of engineers to solve problems when such a knowledge gap arises.

Frequently engineers and scientists are asked to wear many hats, and might not be a materials person by training. Because Thermo-Calc is easy to use, insightful calculations can be performed by anyone regardless of their engineering or scientific background.

When you use Thermo-Calc, all of your information can be stored digitally, shared within your organisation and passed down to new employees. This valuable information can help you secure patents, safeguard your assets and minimise redundancy in your work. Since 1997, Thermo-Calc Software products have been cited in over 1000 patents applications, helping companies safeguard their valuable intellectual capital.   

Optimise Production Processes and Improve the Quality and Consistency of Your Products

Materials specifications are not always as tight as you need them to be.  Small changes in chemistry can give rise to significant differences in the material properties and behaviour. With Thermo-Calc you can predict how a specific composition will behave at different temperatures.  For example, you can predict:

  • Microsegregation during solidification
  • Incipient melt temperatures
  • Phase transformation temperatures,
  • Solvus temperatures,
  • Volume fraction and stability of precipitates
  • The formation of deleterious phases

Sometimes you need to know even more about how a material will behave during a given thermal-cycle, such as the growth/dissolution kinetics of precipitate phases and their size distribution. With optional kinetic add-on modules for diffusion and precipitation, you can simulate:

  • Homogenization treatments
  • Carburization or nitriding treatments
  • Phase transformation kinetics
  • Precipitation during ageing treatments 

Many times, identifying safe and optimal processing windows requires intimate knowledge of the material and how it will behave during processing. Predictions made with Thermo-Calc can give you that knowledge, leading to higher quality, more consistent production, with less downtime and rework.
