Title:
LOW-MELTING HIGH STRENGTH TITANIUM ALLOY AND CASTING
Document Type and Number:
Japanese Patent JP3760488
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent oxidation at the time of casting and to improve workability and surface characteristic by specifying the composition of a Cr- containing titanium alloy and lowering the melting point.
SOLUTION: This alloy has a composition consisting of, by weight ratio, 10-40% Cr, one or ≥2 kinds among 1 to (36.8-1.05[Cr])% Cu, 1-7% Fe, 1-9% Mn, 0.2-15% Pd, 0.6-1.5% Si, and 1-8% Sn, and the balance essentially Ti. In this alloy, the melting point is lowered to ≤1550°C by adding Cr to Ti by 16-40%, and also the solid solution strengthening of an α- and β-phase matrix phase is attained by means of the third components, such as Cu, Fe, and Mn. When this alloy is used for dental plate, crown, bridge, inlay, etc., ≥350 Vickers hardness can be obtained, and also excellent workability can be obtained.
