Abstract

Abstract

The CCT curves of 50W600 and 50W600-Ti were measured by thermal simulator. The phase transformation of the two test steels under continuous cooling had been studied and precipitation behavior in titanium-containing steels was also observed. The results show that the phase transformation temperature of 50W600 is 926-1047 ℃, and the phase transformation temperature range decreases with the increase of cooling rate. The phase transformation temperature of 50W600-Ti is 838-1048 ℃, and cooling rate has little effect on temperature range. The structure of the two test steel matrices basically consists of ferrite, and there is a small amount of cementite under high cooling speed. The microhardness of 50W600 did not change significant with cooling rate, while the microhardness of 50W600-Ti peaked and the precipitation of titanium carbide particles was relatively sufficient at the cold rate of 5 ℃/s
- non-oriented silicon steel,
- Ti microalloying,
- cooling rate,
