| Abstract: | The effect of rare earths(RE) on purifying molten steels, modifying inclusion and micro-alloying are studied in J55 steel. The results show that RE improves the transverse impact energy and increases the resistance of perforation cracking. The extent on modifying MnS and Al2O3 inclusions is dependent on the activity ratios of RE to Mn and RE to Al. The(aRE. as)/(ao. aAl) value determines the relative amount of REAlO3 and RE2O2S and the properties of steel. RE segregation on grain boundary reduces the segregation of phosphorus and sulfur there. |
