Alloy development

Recent initiatives such as the publication in 2008 of the ICME (Integrated Computational Materials Engineering) report by the National Academies in the United States and the launch of the Materials Genome Initiative in June 2011 have highlighted the growing use of computational tools in materials and alloy design. But this is not something that is new.

One of the first commercial applications of Thermo-Calc in 1983, for example, was to accelerate the development of a certain class of stainless steels, helping reduce the initial development cycle from 10 years to 2 years. One benefit in using computational tools is to pre-screen potential candidate compositions, thus guiding experimental work far more efficiently and also assisting in understanding experimental results. Also, alloy design does not have to be limited just to the initial development and optimisation of properties, since one can also apply the modelling tools to consider operational conditions, waste and recycling that enable alloys to be designed for the full lifetime of the material.

Some example uses of Thermo-Calc Software products for alloy development include:

  • Considering the chemical variation of the alloy on the phases that form, the amounts and compositions of those phases and the phase transformation temperatures.
  • Pre-screening large numbers of potential candidate compositions to guide experiments.
  • Coupling both thermodynamic type calculations to other modelling methodologies (e.g. neural network predictions) through TC-Programming Interface such as the TC-Toolbox for MATLABTM.
  • For cast materials, predicting how likely the material is to segregate and how long homogenisation treatments could take.
  • Optimising heat treat schedules for the alloy to balance properties, such as the formation of strengthening precipitates versus corrosion resistance, as one example.
