Abstract
The invention discloses a hydrostatic extrusion forming process for a magnesium alloy/aluminum alloy pipe, which comprises the following steps: (1) composite rolling: impregnating the surface of a magnesium alloy with zinc, heating to 280 to 320 DEG C, heating aluminum alloy to 380 to 400 DEG C, and performing composite rolling on a rolling mill to obtain a magnesium alloy/aluminum alloy continuous casting ingot; (2) homogenization heat treatment: heating the magnesium alloy/aluminum alloy continuous casting ingot to 410 DEG C to 420 DEG C, keeping the temperature for 10 to 24h, and then carrying out air-cooling; (3) hydrostatic extrusion forming: preheating a blank, an outer mold and a mold core to 190 DEG C to 210 DEG C, preheating an extrusion container to 145 DEG C to 155 DEG C, and setting the extrusion deformation ratio to be 2.50 to 2.90, so that a magnesium alloy/aluminum alloy pipe is obtained; and (4) heat treatment: keeping the temperature at 345 DEG C to 355 DEG C for 1 to 4h, and then carrying out water-cooling. As a magnesium alloy/aluminum alloy composite material is obtained according to a specific composite rolling process, and then an aluminum alloy layer is formed outside a magnesium alloy pipe according to a specific hydrostatic extrusion process, so that the corrosion resistance is greatly improved.
Description
Technical field
A kind of the present invention relates to tubular object extruding technical field, more particularly to magnesium/aluminum alloy tubing hydrostatic extrusion shaping
Technique.
Background technology
Magnesium alloy has that thermal diffusivity is good, specific stiffness is high, density is little, biocompatibility is outstanding, damping shock absorption is excellent, electromagnetism
The advantages of shield effectiveness is good, machining property is outstanding, reproducibility is good and reclaims easy, Defence business, mechanical automobile making,
The fields such as Aero-Space, telecommunications, optical instrument, computer and Medical Instruments have huge development potentiality and wide
Application prospect.
But as magnesium alloy is Patterns for Close-Packed Hexagonal Crystal (HCP) structure, plasticity is poor, and conventional extruded mode of texturing efficiency is low, and
And higher extrusion temperature causes the Practical Performance of wrought magnesium alloy low.For fragile material, hydrostatic extrusion is adapted to middle low temperature bar
Large plastometric set under part, can not only significantly improve the yield rate and productivity ratio of extruded product, moreover it is possible to improve its tensile strength, surrender
Intensity and impact flexibility.But the decay resistance of magnesium alloy is very poor, in moist atmosphere or acidity, neutrality, weakly alkaline solution
Corrosion is susceptible to all, therefore, the corrosive nature difference of magnesium alloy has become and restricts its bottleneck further applied.
Magnesium alloy and aluminium alloy have the advantages that density is low, specific strength is high, higher than rigidity, have increasingly in industrial circle
It is widely applied prospect.It is due to magnesium alloy and the popularity and intercrossing of aluminium alloy application and special to which in some platforms
The requirement of performance, magnesium, aluminum and its alloy are connected to form composite construction and just seem very necessary.For example, the boat in spacecraft
Used in its electromotor and parts, the composite construction can mitigate the quality of component, improve the performance of structure：On automobile
Weight can both be mitigated, shock resistance can also have been improved；And corrosive protection of aluminium alloy corrosion can be relatively good, wrap in magnesium alloy outer layer, can
The corrosion resistance of material entirety is improved to be combined into composite board..
