Abstract:

The influence of Sn, Al, Cu, Ti, Sb, Bi, As, Pb, and Ce on the surface tension of pure Fe-C-Si melts of hypo- and hypereutectic point compositions were investigated. The experiments were carried out at 1500 degrees in He atmosphere Sn, Al, Cu, Bi, Sb, As, Pb, and Ce are surface active in the Fe-C-Si melts whereas Ti is inactive. The surface activity of these elements is 1.5 times higher in the hypoeutectic point melts than in the hypereutectic point melts.
