Alloy for high-temperature thermomotive element and high-temperature thermomotive element
专利汇可以提供Alloy for high-temperature thermomotive element and high-temperature thermomotive element专利检索，专利查询，专利分析的服务。并且PURPOSE: To allow a high-temp. thermomotive effect to appear by subjecting a TiNi alloy of excess Ni content to solution heat treatment and then to aging treatment and utilizing the diffusion of the resulting precipitate of excess Ni content into a base phase.
CONSTITUTION: An alloy having a composition consisting of 50.3W53.0atom.% Ni and the balance Ti is subjected to solution heat treatment at about 800W1,100°C to undergo shape memory treatment. Subsequently, the alloy is cooled rapidly to undergo the treatment of formation into TiNi single phase and then constrained in an elastic region to undergo aging at ≤about 600°C, by which a base phase and a Ti
3 Ni
4 phase having complete conformity are anisotropically precipitated. When applied stress is relieved after the above constrained annealing, the specimen is formed into a deformed state. When this specimen having deformation strain is rapidly heated up to >about 600°C so that the anisotropic precipitate is not grown, Ti
3 Ni
4 is penetrated again into the base phase. This alloy for high-temp. thermomotive element can be used for measuring element for the temp. in a furnace, abnormally elevated temp. due to heating, etc.
