Influence of Nb Element on Continuous Cooling Transformation and Microstructure Change of Weathering Steel AITranslate
Abstract AITranslate
Investigation was made of the continuous cooling transformation （CCT） curves of the weathering steels with Nb and without Nb by Gleeble-1500D thermal simulator,and the influences were analyzed of the Nb element and cooling rate on CCT curve and microstructure changing law. The results show that the addition of Nb inhibits phase transformation of the weathering steel and decreases its phase transformation temperature,causing CCT curve to move to the lower right. Under the condition of cooling rate 15 ℃/s,the microstructure of the weathering steel with Nb significantly changes. With the increase of cooling rate, the hardness of the weathering steel with Nb increases gradually. Lots of bainite forms at the cooling rate of above 5 ℃/s,and some martensite forms at the cooling rate of over 20 ℃/s,which is good for strength and performance improvement of the weathering steel.
