Problems solved by technology

Although the mechanical alloying method to prepare dispersed powder is relatively simple and the cost is low, the billet prepared by the mechanical alloying method is a loose porous material with a low degree of densification. Whether it can be successfully applied depends on the The properties obtained during the plastic densification process after billet making, the subsequent plastic processing of porous preforms is necessary

Embodiment Construction

[0011] In the self-made 50KG high-energy ball mill, Al with particle size ≤ 1 μm 2 o 3 powder or ZrO 2 The powder and the copper powder with a particle size of ≤60 μm are proportioned by mass at 0.35%, the ball-to-material ratio is 6, the rotation speed is 150 rpm, the average diameter of the balls is about 8 mm, and the ball milling time is 2 hours. In order to prevent excessive sticking of powder during ball milling, 0.5% zinc stearate was added during mixing. In order to prevent the oxidation of copper, filled with high-purity N 2 Gas, inject the mixed material into a copper tube with a diameter of 100mm, a wall thickness of 2mm, and a length of 350mm, and then put it into a 1650T extruder for compaction. After removing the skin of the pre-compact, preheat at 300°C for 1 hour in an ammonia decomposition reducing atmosphere furnace, heat at 600°C for 1 hour, and finally sinter at 900°C for 6 hours. Its high-temperature strength at 600°C is measured to be 200 MPa, and its...

Abstract

This invention relates to a method of producing the dispersion consolidating copper alloy material. It uses machinery alloyed to blend the metal oxidation powder and copper powder with a certain proportion, and then agglomerating them, then using water sealing heat extrusion to do cold plastic deformation processing to obtain the product.>The advantage of this invention is that it can make sure the quality of the copper alloy material, and the cost is low, the technique parameter is easy to control.

Description

technical field [0001] The invention relates to the preparation and plastic processing of a metal material, in particular to a production process for a dispersion-strengthened copper alloy material with excellent high-temperature mechanical and electrical properties. Background technique [0002] With the development of my country's automobile industry-based vehicle manufacturing industry, household appliances and electrical and electronic manufacturing industries, on the one hand, the application of resistance welding technology based on automation, high production efficiency and good welding quality is more widely used, as a resistance welding consumption The amount of electrode materials for products is increasing; on the other hand, materials for contacts, inserts, and lead frames used in electronics, electrical appliances, and instruments, and for advanced electrical contact elements, inserts, and switches also require a large number of materials with excellent high-tempe...
