Abstract
The effects of cooling rate, forming method and alloying on the suppression of ordering reaction have been studied in high Si steels. Four kinds of cooling were used : air cooling, oil quenching, water quenching and ice brine quenching. An order-disorder transition diagram was obtained in terms of Si content and cooling rate. It was confirmed that the cooling rate was a more important factor to suppress the ordered phase than annealing conditions. When 0.15 wt% Mn was added to 6.5 wt% Si steel and fabricated by spray casting, the ordering did not take place.
