The goal of the Materials Genome Initiative (MGI), announced in 2011, is to enable the development and deployment of new materials in ‘half the time and half the cost’. The introduction of new materials, or even minor changes in composition of a known material, often requires a long time for processing adjustments, and development of an entirely new material is even more challenging. Proper processing is required to achieve a well-designed microstructure and products with the desired properties. Today’s technology relies heavily on materials with complex compositions that often consist of several phases.
JMATPRO FUNCTIONS CODE
The availability of the source code can greatly benefit scientists in academia as well as in industry in the development of new models and assessment of model parameters from both experimental data and data from first principles calculations.
JMATPRO FUNCTIONS SOFTWARE
The OC software is distributed under a GNU license. At present, no other high quality open source software is available for calculations of multicomponent systems using CALPHAD-type models, and it is the goal of the OC source code to fill this gap.
This is important for coupling validated thermodynamic as well as kinetic data in such simulations for obtaining realistic results. The OpenCalphad (OC) software, discussed here, has a simple programming interface to facilitate such integration in application software. A number of CALPHAD software are available for the calculation of properties of multicomponent systems, and the majority are commercial products. CALPHAD calculations can be carried out as stand-alone calculations or can be carried out coupled with simulation codes using the result from these calculations as input. A large variety of data, such as phase diagram and solubility data, including consistent thermodynamic values of chemical potentials, enthalpies, entropies, thermal expansions, heats of transformations, and heat capacities, can be obtained from these databases. The CALPHAD (Calculation of Phase Diagrams) technique has made it possible to calculate properties of multicomponent systems using databases of thermodynamic descriptions with models that were assessed from experimental data. Thermodynamic data are essential for the understanding, developing, and processing of materials.
