Abstract
The making process of electrode alloy includes heating the alloy to 850-900 deg.c and maintaining for 2 hr before upsetting and drawing; heating the alloy to 950-1000 deg.c and maintaining for 2 hr before abruptly cooling inside medium for solid solution treatment; cold deformation of 40-50 %, heating to 480-500 deg.c and maintaining for 4 hr for ageing treatment; and final cooling in the air. Compared with available technology, the heating to 950-1000 deg.c, maintaining for 2 hr and abruptly cooling inside medium can avoid solid solution to decompose and obtain ideal saturated solid solution; and the cold deformation of 40-50 % after the solid solution treatment aims at increasing the crystal default of the solid solution to form more non-spontaneous as exsolution kernel and to speed the decomposing of the solid solution in ageing treatment. The alloy thus produced has hardness up to 90-101, softening temperature of 600-650 deg.c and conductivity of 45-55 %.
Description
Technical field:
The present invention relates to chemical field, be specifically related to a kind of alloy, especially a kind of manufacture method of electrode metal.
Background technology:
Electrode metal is the critical material in the resistance welding process, its effect is to provide electric current and pressure simultaneously to welded part, during welding, since the different requirements of welded part, the electric current that passes through on the electrode from tens of amperes to tens thousand of amperes, pressure from the tens public Rooms to several metric ton, and be to bear pressure simultaneously by producing pyritous at electric current, therefore, electrode materials must have good electroconductibility, anti-molten viscosity and higher hardness and high-temperature capability.The world generally adopts the electrode materials of the alloy of high strength, middle electric conductivity as stainless steel, high temperature steel and superalloy lap resistance welding at present, though this alloy also can play a role in the occasion that needs certain degree of hardness and high electrical conductivity, but it can not satisfy the requirement of high rigidity and high conductivity simultaneously, therefore is not suitable for doing the lap resistance welding electrode metal of stainless pot, heat-resisting pot and superalloy.
Summary of the invention:
Technical problem to be solved by this invention is: because in the prior art, electrode materials must have good electroconductibility, and anti-molten viscosity and higher hardness and high-temperature capability.The world generally adopts the electrode materials of the alloy of high strength, middle electric conductivity as stainless steel, high temperature steel and superalloy lap resistance welding at present, though this alloy also can play a role in the occasion that needs certain degree of hardness and high electrical conductivity, but it can not satisfy the requirement of high rigidity and high conductivity simultaneously, therefore is not suitable for doing the lap resistance welding electrode metal of stainless pot, heat-resisting pot and superalloy.The present invention is for solving the above-mentioned technical problem in the prior art, the technical scheme that is adopted provides a kind of manufacture method of electrode metal, the manufacture method of described alloy is that alloy is heated to 850-900 ℃, under this temperature, be incubated 2 hours and carry out pier and pull out, and then be heated to 950-1000 ℃, after this temperature is incubated 2 hours, be put into chilling in the medium, to carrying out 40～50% cold deformation through the alloy after above-mentioned solid molten the processing, and then be heated to 480-500 ℃, and carried out ageing treatment in 4 hours in this temperature insulation, be put in the air at last and cool off.
The present invention and prior art contrast, alloy be heated to 950-1000 ℃ be incubated 2 hours again after at the medium chilling, can avoid the decomposition of sosoloid like this, to obtain ideal supersaturation Solid solution.Alloy after the solution treatment is carried out the cold deformation of 40-50%, and purpose is to increase the lattice defect of supersaturation Solid solution, forms more non-spontaneous nucleation and becomes the precipitation core, to accelerate the decomposition of ageing treatment to sosoloid.Adopt manufacture method of the present invention, the main hardness that gets of gained alloy can reach 90-101, and softening temperature 600-650 ℃, electric conductivity 45-55%.
