Abstract : A 1010 carbon steel, in the annealed condition, was used to study the dissolution behavior of Fe3C particles under conditions of rapid heating and short times at temperature. The study used a capacitor-discharge pulse heating and quenching system to achieve heating rates of 1,000,000 C/sec, quenching rates of 10,000 C/sec, and times at temperatures from 15 to 500 msec. A qualitative description is given of the effect pulse heating of alloys, into the two phase (ferrite plus austenite) and into the single phase (austentie region), have on the samples. Metallographic evidence is presented confirming the suggestion that pulse heating and rapid quenching can produce regions having higher carbon concentrations than the same alloy heated under equilibrium condtions.
