Abstract
Mechanical spectroscopy is a unique technique that is capable of detecting extremely fine traces of rolling oil left on the surface of cold-rolled steel sheets. In this study we have demonstrated that a characteristic mechanical loss spectrum occurs in the,low-temperature range from 180 K to 280 K only in the two following situations: (1) if traces of the rolling oil are left on the surface of sheets or (2) if the sheets are covered with a thin film of the rolling oil. Nearly the same loss spectra have been observed in subresonant mechanical loss measurements of paper micro-samples covered with a thin film of rolling oil. It can therefore be concluded that the observed mechanical loss phenomena take place in the rolling oil, that is, they do not depend on whether the substrate is metallic or paper. Moreover, the subresonant mechanical spectroscopy can readily resolve the complex mechanical loss spectrum into three constituent peaks located at 188 K, 215 K, and at around 270 K, respectively. Rolling oils containing different amounts of sulphur generate low-temperature peaks of substantially different height. The asymmetrical peak observed at 270 K on heating is produced by a phase transformation of the rolling oil from the solid into liquid phase.
