Experimental Ti-13%Zr and Ti-13%Zr-5%Cu alloys were made in an argon-arc melting furnace.
The grade 2 CP Ti was used to control. To investigate the surface reaction layers produced by the reaction with mold materials and the influence of the reaction layers on the hardness of castings, A phosphate bonded SiO2 base investment was used as mold material, and microstructure observation and hardness test were performed.
The surface reaction layers of Ti-13%Zr and Ti-13%Zr-5%Cu alloys were thinner than that of CP
Ti had a clearly multiple structure. A difference of the hardness between surface and inner of the
Ti-13%Zr and Ti-13%Zr-5%Cu alloys became less than that of CP Ti.
From the results, it was found that the Ti-Zr-(Cu) based alloys were possible to cast with SiO2
base investment without the great changes of mechanical properties of the castings.
