摘要

Laboratory investigation on formation of inclusion in Ti-Al complex deoxidized C-Mn steel was carried.The results are as follows : when Al content in steel is very low ( [ Al] = 0.000 5%),0.003% < [ Ti] < 0.007%,the inclusions is the Al2O3-SiO2 - MnO-TiOx composite inclusion;[ Ti];0.OO9%,the inclusion is Tio in the steel.When [ Ti] = 0.005%,[ Al] < 0.001%.the inclusions is the A12O3-SiO2 - MnO-TiOx composite inclusion;[ Al] > 0.006%,inclusions would be pure A12O3 The experimental results agree with the thermodynamics conclusions.
