Thermo-Calc 2016a offers significant speed improvements when compared to previous versions of the software.

The speed improvements were achieved by optimizing global minimization and optimizing two of the largest databases.

## Global Minimization Optimized

Global minimization has been optimized in Thermo-Calc 2016a, improving the speed of most calculations, including single point equilibrium, property diagram and phase diagram calculations as well as Scheil solidification simulations.

Benchmark tests compared the calculation speed improvements seen in 2016a to 2015b and, in some cases, to Thermo-Calc Version S.

In tests with property diagram calculations for 5 to 8 component alloy systems, the speed improvements ranged from 9 to 38%, with significant improvements shown for the larger TCNI8, TCMG4 and TCFE8 databases, as shown in figure 1.

When the comparisons were made for phase diagram calculations at a constant temperature with 5 to 12 component alloys, the speed improvements ranged between 5 to 17%, as shown in figure 2.

## Database Optimization

Two of the large databases, TCHEA for high entropy alloys and TCNI versions 8, 7 and 6 for nickel, have also been optimized, improving both loading and calculation times.

Benchmarking of the loading time of the original TCNI8 compared to the new, optimized version using Thermo-Calc 2016a shows speed improvements of 49 to 55%, as shown in figure 3. Similar results were found for the loading times of TCNI 7 and 6 and TCHEA, the high entropy alloys database.

Benchmarking for the TCNI8 database was also done to compare calculation times in Thermo-Calc Version S, 2015b, 2015b with the optimized database and 2016a with the optimized database. Results show speed improvements of 29-68% in Thermo-Calc 2016a when compared to 2015b with the non-optimized databases, as shown in figure 4.

Three of the calculations in figure 4 were taken from examples included in the TCNI8 Extended information flyer which can be found on our website.
