STK Process

STK (Simultaneous Transformation Kinetics) software is an add-on utility for the SAMP software. Thermal cycling during the layer-by-layer deposition of the blown powder additive manufacturing process leads to solid state transformations and variable microstructure evolutions in the build part. ISEP simulates this microstructure evolution for alloys Ti-6Al-4V and IN718. The utility extracts and uses the location-dependent, time-temperature data generated by SAMP as input to predict the as-built microstructure at user-defined locations of interest.
