Abstract
In order to solve the problems of excessively wide elastic stress platform, narrow temperature range caused by superelasticity and excessively large alloy grains in nickel-titanium binary alloys, the invention provides a titanium-based five-element alloy. Titanium-based five-element alloys include Ti elements, Ni elements, Cu elements, Cr elements, and B elements, wherein Ni elements account for 45%-55% of the overall weight of the alloy, and Cu elements account for 1%-10% of the overall weight of the alloy. %, the Cr element accounts for 0.1%-2% of the overall weight of the alloy, the B element accounts for 0.1%-2% of the overall alloy weight, and the rest is Ti element and inevitable impurities. The titanium-based five-element alloy material of the invention has high elastic strain and excellent hot and cold processability, and is suitable for manufacturing orthopedic wires for oral orthodontic treatment, and the manufactured orthopedic wires are soft and easy to bend.
Description
technical field [0001] The invention relates to an alloy material, in particular to an alloy material which can be used for oral orthodontics. Background technique [0002] Whether the teeth grow neatly not only affects the appearance, but also affects the pronunciation, chewing function and the health of the teeth, and even leads to facial deformities and unnecessary psychological pressure. Orthodontics, in layman's terms, is to arrange the misaligned teeth into order and solve the above-mentioned problems caused by misaligned teeth. Orthodontic treatment technology has been widely used for its short chair-side working time, simple clinical operation and high-quality treatment effect. In orthodontic treatment, the orthodontic wire is the key component of the appliance to generate force, and it plays a decisive role in achieving the best possible occlusal relationship and maintaining stability after healing, as well as increasing the beauty of the face. . [0003] In the ...
