Paper published about the influence of temperature on insitu eddy currents measurements

This paper describes and analyses the impact of the temperature on the insitu eddy current measurements during PBF-LB manufacturing. The research has been conducted by AMiquam, ETHZ, and inspire in partnership supported by Innosuisse.

In a nutshell: yes, as expected, temperature affects the eddy current response because of the change in the electrical conductivity of the measured part, this is just physics. But, good news, this effect is small compared to that of the defects that matter for production (thanks to the low dependence of the electrical conductivity with temperature in alloys) and, most importantly, it can be taken into account either by IR imaging or by numerical simulation.
