Area of Science:

  • Materials Science
  • Manufacturing Engineering
  • Process Monitoring

Background:

  • Metal additive manufacturing (MAM) requires robust process monitoring to reduce build uncertainties and improve repeatability.
  • In situ thermographic imaging is a promising monitoring technique, but accuracy is limited by differing surface emittances between powder and solidified parts.
  • Accurate temperature data is crucial for understanding and controlling the build process.

Purpose of the Study:

  • To develop a calibration method for thermographic data to correct for surface emittance variations in MAM.
  • To analyze thermographic data to identify material phase transitions during the build process.
  • To correlate thermal characteristics with microstructural variations for improved build control.

Main Methods:

  • Utilized thermographic imaging for in situ monitoring of the MAM process.
  • Developed a calibration technique to account for emissivity differences between powder and solid metal.
  • Analyzed corrected temperature profiles to determine thermal gradients and solid-liquid interface velocities.
  • Correlated thermal data with experimentally observed microstructural features.

Main Results:

  • A corrected temperature profile was successfully generated by accounting for surface emittance changes.
  • Thermal gradients and solid-liquid interface velocities were approximated from the calibrated data.
  • These thermal parameters were correlated with microstructural variations in the as-printed part.
  • Demonstrated the link between process monitoring and microstructure control.

Conclusions:

  • The developed thermographic calibration method enhances the accuracy of in situ temperature measurements in MAM.
  • Process monitoring, through calibrated thermography, can effectively track and control build repeatability by relating thermal data to microstructure.
  • This approach offers a pathway to reduce uncertainties and improve the quality of metal additive manufactured parts.
