High-frequency in situ analysis of microstructural changes during thermal and thermomechanical processes

Project Information:

  • Project Title: High-frequency in situ analysis of microstructural changes during thermal and thermomechanical processes
  • Acronym: HISAMP
  • Duration: 36 Month (Start: 01.08.2020)
  • Funding: FFG The Austrian Research Promotion Agency
Goal: Laser ultrasound as an in situ analysis method in thermomechanical simulator


The constantly increasing demands for components in terms of mechanical properties, functionality and minimum production costs pose huge challenges for the science community. Novel processes such as Plasma-Metal-Deposition (PMD®) technology enable the additive production of complex parts in a very short time. However, this requires extensive experimental development of a process parameter set for each material. To reduce this experimental effort, finite-element (FE) simulations with coupled microstructure modelling can be used.

However, the research time for determining a parameter set for a microstructure model for one material is usually three years. In this project, research is therefore being conducted on a new laser-ultrasound system for a Gleeble testing machine, in which the measuring frequency is significantly increased and new evaluation algorithms are implemented.

The synchronized data of the laser-ultrasound system and the Gleeble will be calibrated with reference investigations from light- and scanning-electron-microscopy and evaluated in a semi-automatic sequence to be developed. The necessary scripts are to be programmed in such a way, that the sequence of data analysis via the derivation of the parameter sets necessary for the microstructure simulation up to the implementation in the FE-code becomes possible in a minimum of time. The significant reduction in the development time of new parameter sets should then also enable industries with less research affinity to carry out simulation-supported process optimisation with microstructure modelling.
