Title:
TITANIUM ALLOY
Document Type and Number:
Japanese Patent JP3766519
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide Ti-Mn-Ag and Ti-Mn-Ag-Co-Si alloys as low m.p. alloys for joining titanium and titanium alloys.
SOLUTION: The titanium alloys are ones having a compsn. contg., by weight, 3 to 15% Mn and 5 to 30% Ag, contg. 1 to 5% Co and 0.1 to 1.5% Si according to necessary, in which the content of Co+Si is also limited to ≤5.1%, and the balance substantially Ti. In the former Ti-Mn-Ag, Mn is added in a range in which its hardening caused by Mn is allowable to reduce its m.p., and Ag imparts fitness to the base metal as a joining material. Moreover, the latter Ti-Mn-Ag-Co-Si is the alloy furthermore reducing its m.p., flowing into a narrow joined part and obtaining high strength by a small cross-sectional area. Co and Si have effect of reducing the m.p., but they raise its hardness, therefore, the compsn. is the one suppressing the hardnesss in relation to both elements. Moreover, the elements to be added for alloying are the ones through the consideration of biological safety, and, furthermore, they are joinable without eroding the base metal in titanium and titanium alloys in artificial joints and dental materials. Moreover, defects in casting are hard to occur therein as alloys for casting.
