Abstract
The utility model relates to an aging thermal treatment device for a copper alloy under DC. The device comprises a thermal treatment furnace which is provided with a conducting wire for connecting a copper alloy sample to be treated and (with) a DC power supply. Because the aging thermal treatment device for the copper alloy under DC is provided with the conducting wire, the motions of vacant sites inside the copper alloy sample are influenced by the DC, and the vacant sites are gathered around a dislocation and a crystal boundary to provide a nucleation site for a precipitated phase; in addition, the DC has influences on energy barriers required to be overcome in the precipitation of solid solution atoms from a copper matrix and further has influences on the quantity and distribution of aging-precipitated second phases to control the structure of the copper alloy, so that the copper alloy has excellent comprehensive mechanical performance; thereby, the aging thermal treatment device for the copper alloy under DC solves a problem that the high strength and high electrical conductivity of the copper alloy cannot be incompatible.
Description
Technical field
The utility model relates to copper alloy heat treatment technics field, especially timeliness thermal treatment unit under the Albatra metal-galvanic current.
Background technology
Copper alloy with high strength and high conductivity is important copper alloy functional materials; Be widely used in high-speed railway osculatory, high tensile line, high-fidelity audio frequency and video line, resistance welding electrode, conticaster crystallizer, the cooling of thermonuclear reactor experiment wall, microwave tube structure and fields such as conductive component, magnetic artillery track, aerospace connector assembly wire and high-voltage switch contact, significant to the enforcement of China's Important Project.
Characteristic parameters such as the quantity of precipitated phase, size, form and distribution will produce very big influence to the intensity and the electric conductivity of alloy behind the alloy aging.HS is a pair of conflicting characteristic with high conduction in the copper alloy; In general then intensity is low for the electric conductivity height; Intensity height then electric conductivity is difficult to improve, and therefore how to keep on the high-intensity basis, and the electric conductivity that improves alloy is the research topic of researchers always.
Yet, present copper alloy handle and Application Areas in, the HS of copper alloy and high conductivity remain and can't get both.
Summary of the invention
The purpose of the utility model is to provide timeliness thermal treatment unit under the Albatra metal-galvanic current; Under the effect of galvanic current, influencing form, distribution, quantity and the size of precipitated phase, thereby solve the HS of copper alloy and the problem that high conductivity can't get both.
In order to address the above problem; The timeliness thermal treatment unit adopts following technical scheme under the copper alloy galvanic current of the utility model: timeliness thermal treatment unit under the Albatra metal-galvanic current; Comprise heat treatment furnace, said heat treatment furnace is provided with and is used for lead that pending copper alloy sample is connected with direct supply.
Said heat treatment furnace is a tube furnace; Said tube furnace comprises boiler tube; Be fixed with more than two the refractory walls with the coaxial setting of boiler tube on the inner-wall surface of said boiler tube, said each refractory walls is equipped with the through hole that supplies the copper alloy sample to pass along the axially spaced-apart setting of boiler tube on each refractory walls.
Said heat treatment furnace is provided with thermopair.
Said heat treatment furnace is provided with inlet mouth and the air outlet that supplies the rare gas element turnover.
Because the timeliness thermal treatment unit has described lead under the copper alloy galvanic current of the utility model; Therefore can exert an influence through the motion of galvanic current to the inner room of copper alloy sample, room gathering around dislocation and crystal boundary provides the forming core place for precipitated phase; In addition, galvanic current also breaks away from the copper matrix to the solid solution atom separates out the required energy barrier that overcomes and exerts an influence, thereby and then the quantity of timeliness being separated out second phase and the tissue of may command material of exerting an influence that distributes, make material obtain good comprehensive mechanical performance; Thereby the HS of copper alloy and the problem that high conductivity can't get both have been solved.
