Description
Static and dynamic aging in high carbon steel, mainly related to interaction of interstitial solute atoms and dislocations, are commonly assessed by conventional mechanical testing and mechanical spectroscopy (internal friction). This paper describes and illustrates the use of other techniques: differential scanning calorimetry and to a lesser extent M”ssbauer spectroscopy. Thermoelectrical power measurements, scanning tunnel and atomic force microscopy have also proven to be useful semi-quantitative measurement tools.
