Thermal desorption spectroscopy study of experimental Ti/S containing steels

Abstract
This research studied hydrogen trapping by Ti/S containing precipitates in two experimental steels, C076 and C077. Ingots were hot and cold rolled to sheets of 1.2 mm thickness. Precipitates were formed during a well designed heat treatment. Thermal desorption spectra (TDS) were measured after electrochemical hydrogen charging. C077 and C076 produced low temperature TDS peaks at similar to 90 and similar to 140 degrees C, with activation energies of similar to 34 kJ mol(-1), consistent with hydrogen trapping at grain boundaries. C076 had a higher hydrogen content attributable to the larger grain boundary area. C076 also had higher temperature TDS peak at similar to 270 degrees C, with an activation energy of similar to 58 kJ mol(-1), attributed to hydrogen trapping associated with Fe1.2Ti0.8S2 precipitates.
