THE PRODUCTION AND EVALUATION OF THE PROPERTIES OF TITANIUM ALLOY CASTINGS,

Abstract

A consumable electrode vacuum arc melting procedure using a 'skull' melting and pouring device produced satisfactory titanium castings. Centrifugal casting gave improved definition and surface finish to the castings. A ceramic shell moulding technique based on the lost wax process produced castings with good surface finish and accuracy, and with little surface contamination. Satisfactory castings were produced in a range of titanium alloys with tensile strengths in the range 28-55 tons/sq in. A pouring technique using consumable electrode vacuum arc furnace and copper and graphite crucibles sealed with a titanium plug which eventually melted to effect pouring was not satisfactory.
