  • To refine experimental data using R software for accurate thermal diffusivity values.

Main Methods:

  • Laser flash analysis using a DLF1600 instrument with a specialized powder cell.
  • Measurements conducted at various temperatures.
  • Validation against reference materials and existing literature.

Main Results:

  • Initial experimental results for powder samples showed lower thermal diffusivity than expected.
  • R software analysis was employed to adjust and improve the accuracy of the thermal diffusivity data.
  • Obtained powder thermal diffusivity values closely approximated the actual material properties.

Conclusions:

  • Accurate measurement of IN718 powder thermal diffusivity is achievable using laser flash analysis with appropriate data correction.
  • R software analysis is effective in refining experimental thermal diffusivity data for powders.
  • Precise thermal property data is essential for optimizing LPBF processes and material performance.
