      abstract     = {The formation of austenite during both slow and fast
                      heating (0.25–100 C s1) was investigated for different
                      microstructures of aselected low-alloy steel. With the
                      simultaneous use of dilatometry and high-energy X-ray
                      diffraction, it was possible to follow not onlythe global
                      progress of the austenitization, but also the individual
                      evolutions of each phase (ferrite, cementite and retained
                      austenite ifpresent in the initial microstructure). The
                      results confirm earlier published data regarding the ease of
                      austenitization of different initialmicrostructures
                      (ferrite–pearlite, bainite and tempered martensite). More
                      importantly, two stages were clearly identified,
                      correspondingto the simultaneous transformation of ferrite
                      and cementite, followed by the progressive disappearance of
                      the remaining ferrite. Whilethis is well known for
                      ferrite–pearlite microstructures, it is not yet documented
                      for bainite and tempered martensite. Microstructure
                      evolutioncalculations based on a diffusion-controlled
                      mechanism helped rationalize the differences observed
                      between the three initial microstructures.In addition, they
                      also strongly suggested the existence of a critical carbide
                      size beyond which the second austenitization phasewould
                      correspond to carbide dissolution instead of ferrite
                      transformation.},
