Influence of Al on Evolution of the Inclusions in Ti-Bearing Steel with Ca Treatment

Metals, 2019
Experimental simulations of steelmaking with different amounts of aluminum were achieved in the tube furnace at 1873 K and field scanning electron microscopy and energy dispersive X-ray spectroscopy (FE-SEM and EDX) were employed to explore the ...
