摘要：

Comparative studies were carried out on the effect of high magnetic field on the pearlite transformation of Al-containing high carbon steels under the furnace slow cooling condition. For 1.37AI-bearing high carbon steel, the amount of pearlite was only 6 +/- 3 vol.-% without magnetic field, whereas full pearlite was obtained under a 12-T high magnetic field. For free-AI high carbon steel, no pearlite transformation occurred, whereas lots of bainite were formed under a 12-T high magnetic field.ln addition,the interlamellar spacing of pearlite increased from 100 +/- 7 to 112 +/- 18nm by the application of a 12-T magnetic field. It has been proved that the pearlite transformation of high carbon steel was promoted by high magnetic field and by the addition of aluminium.
