Abstract
A titanium stabilized 18-12 type stainless steel was statically aged at 700 and 750° C, and the resulting MC precipitates were analysed using atom-probe field-ion microscopy. For all ageing times studied (from 3 to 1170 h), the MC particles were found to contain chromium in addition to titanium and carbon. The chromium content was found to decrease from 14 to 5 at% during ageing at 700° C, whereas the carbon content increased from 40 to 50 at%. The effects of precipitate composition on the particle-matrix interfacial energy and on the stability of MC relative to M23C6 are discussed.
