  • Description:
    The effect of fluoride inclusions on the properties of titanium produced from the Bureau of Mines developed induction slag melting process is of concern to members of the titanium industry. The objective of the research was to determine the effect of caf2 inclusions on the properties of titanium and its survival rate during melting. The data were obtained from single-induction-slag- melted ingots prepared with the normal addition of 4 pct and also with 2- and 1-pct additions of caf2 slag. The results of this effort showed that the mechanical properties of single-induction- slag-melted ti-6a1-4v alloy exceed the minimum values specified in aerospace materials specification for titanium alloy bars and forgings ams4928h, but these materials are much more notch sensitive in fatigue than normal ti-6a1-4v alloy titanium. First and second vacuum-arc remelts of single-induction-slag-melted ingots fragmented and increased the number of inclusions, while reductions in the amount of flux resulted in an upward trend in the spatial distance between pores in an x-y plane.
