KEY FEATURES
Particle precipitation kinetics
based on mean field theory
Multicomponent nucleation and
growth models

CALPHAD- based
thermodynamic and kinetic
databases
Estimates multicomponent
interfacial energy
The Precipitation
module (TC-PRISMA)
is an add-on module
within Thermo-Calc which
treats concurrent
nucleation,
growth/dissolution and
coarsening under arbitrary
heat treatment conditions
in multicomponent and
multi-phase systems using Langer-Schwartz theory and the
Kampmann-Wagner numerical approach.
Evolution
The Precipitation module has been jointly developed through a
collaboration of Thermo-Calc Software AB and Questek Innovations.
The module incorporates and improves on key models and algorithms
from QuesTek’s PrecipiCalc® precipitation simulation software, which
QuesTek developed (for more than 10 years) as part of its Materials by
Design® technology to computationally design innovative new alloys.
Consistently Maintained and Updated
The Precipitation module (TC-PRISMA) is on a two-times-per-year
release cycle, and customers with a maintenance and support
subscription for it receive these updates for free.
Technical Support and Training
The Precipitation module is backed by a dedicated customer technical
support team. We also have agents around the world, and a subsidiary
in the USA, who provide local customer support. Training courses are
offered twice a year in Stockholm, Sweden, and Pittsburgh, PA, USA, as
well as other locations around the world.
High Quality Thermodynamic and Mobility Databases
In order to use the Precipitation module, both a thermodynamic and a
PLATFORM
kinetic database are needed. The thermodynamic database is the same
Windows, Linux and Mac OS
as used by Thermo-Calc, and the kinetic database is the same as used
Refer to our website for
with the Diffusion module (DICTRA), ensuring self-consistency across
complete system requirements
the Thermo-Calc Software range of products. Most of our
LICENSES
thermodynamic databases also contain molar volume data, which is
Single machine or network install needed in a precipitation simulation. Since a mobility database is
required, the module is most suited to applications involving:
Annual or perpetual options
Steel and Fe based alloys
Ni-based alloys
Al- alloys
Ti- alloys
License fees depend on several
factors, i.e., database selection
Si- alloys
Cu- alloys
Mg- alloys
