Thermodynamic and mobility databases are the pre-requisite for predictive kinetic simulations of precipitation and microstructural evolution. We can tailor special databases for the optimization of special technological products in terms of alloying and processing (thermo-mechanical treatments and their effects on phase transformations, precipitation and strengthening). Find some typical examples below.

Magnesium database

 
 

Elements: Mg, Al, Ba, Ca, Mn, Si, Sr, Zn

Some standard applications: Mg-alloys of the AZ-series: Calculation of phase stabilities and phase compositions, evaluation of microsegregation, precipitation simulation.

Special simulations: Phase stabilities and precipitate evolution in special creep-resistant Mg-alloys for automotive applications, phase stabilities and precipitate evolution in bio-degradable Mg-alloys for medical applications.

Magnesium High-strength low-alloy

 

Elements: Mg, Zn, Ca

The thermodynamic database has been used for precipitation simulations in biodegradable Mg-base material, Hoftstetter et al., Acta Mater. 98 (2015) 423-432

Molybdenum refractory database

 

Elements: Mo, Hf, Ti, C, O

Some standard applications: Determination of carbide and oxide stabilities in powder-metallurgically processed MHC alloy, determination of optimized conditions for solid solution treatment.

Special simulations: Simulation of heterogeneous precipitation, evaluation of the role of oxygen on precipitation.

Shape memory alloys database

 

Elements: Ti, Ni, Cu, V

 Some standard applications: Evaluation of intermetallic phase stabilities in Cu- or V-alloyed Ti-Ni-base shape memory alloys, determination of solvus temperatures and compositions of metastable precipitate phases.

Special simulations: Evaluating the role of alloying on the martensitic transformation, simulation of time-temperature-precipitation behavior.
