Abstract
The infrared absorptances of highly polished Ti‐6Al‐4V and 304 stainless steel have been measured between 2 and 20 μm and at temperatures up to 550 °C. Small positive temperature coefficients for both alloys were observed. A generalized Drude model has been developed to interpret the data; the weak temperature dependence of the absorptance has been attributed to the relatively small effect of phonon scattering in these disordered alloys.This publication has 3 references indexed in Scilit:
