Abstract
Ti-20%Zr-X%Cr(X=0,5) based alloys not containing hamful Al and V were newly designed inorder to reveal their possibility for dental casting alloys, and melted in argon-arc casting machine.The mechanical properties were evaluated by using universal testing machine. The tensile strengthand %elongaton of the alloys markedly increased with Cr content. The Ti-20%Zr-5%Cr alloyshowed a similar tendency with Ti-6%Al-4%V alloy in tensile strength, but surpassed in%elongation. From these results, it was concluded that new alloys for successful dental castingmaterials should be designed as Ti-Zr-Cr based alloys.
