Description
Technical field
The present invention relates to metal material shaping and manufacture field, a kind of Hot Deformation Strengthening of magnesium-rare earth is specifically related to
Method, by controlling extrusion process and parameter, improves the plasticity of material while material high intensity is kept.
Background technology
Magnesium alloy is because its density is low, specific strength is high, while the advantages of having good creep resistance and antidetonation energy-absorbing concurrently,
The fields such as national defence, Aero-Space, automobile making are with a wide range of applications.It is well known that traditional Mg-Al-Zn and Mg-
Zn-Zr systems alloy strength is relatively low, although in these alloys, can be by adding rare earth element（Ce, La, Nd and Y）, by
The second stable phase is formed under high temperature so that this kind of magnesium alloy resists in 200 DEG C and temperatures above with high intensity with good
Creep properties, when operating temperature reaches 250 DEG C and the above, the mechanical property of this kind of magnesium alloy typically can be reduced substantially.In Mg-RE
It is that Mg-Gd systems alloy has relatively stable low creep rate and higher creep resistance, its excellent room temperature and high temperature in alloy
Mechanical property is even more than the business magnesium alloy such as WE54 and QE22, has obtained the common concern of domestic and international expert and scholar.Drits
Et al. systematic research has been carried out to the mechanical properties of Mg-Gd bianry alloys earliest, find its room temperature strength up to 400MPa with
On, but its elongation percentage at room temperature is less than 2%, and the deformation difficulty that low elongation percentage is brought seriously hinders its extensive use.Therefore,
It is one of heat resistance magnesium alloy application field key issue urgently to be resolved hurrily to improve Mg-Gd systems Alloy At Room Temperature plasticity.
Publication No. CN102828133A Chinese patent application discloses a kind of preparation side of ultra-high-strength/tenacity magnesium alloy
Method, its alloy composition is Gd：6~13%, Y：2~6%, Zr：0.3~0.8%, by carrying out strength to semicontinuous magnesium alloy cast
Thermal deformation, then magnesium alloy after thermal deformation is subjected to quick warm deformation at 110~150 DEG C, deformation velocity is 15~24mm/s；Quickly
140~250 DEG C/23~38h aging strengthening models are carried out after warm deformation, total deformation is 10~40%.Warm deformation state Alloy At Room Temperature resists
Tensile strength is 610~647MPa, and yield strength is 547~585MPa, and elongation after fracture is 6~10%.Aging state Alloy At Room Temperature resists
Tensile strength is 710~749MPa, and yield strength is 675~710MPa, and elongation after fracture is 3.8~6.9%.
Publication No. CN102392165A Chinese patent application disclose a kind of wrought magnesium alloy with high intensity and
The preparation method of its squeeze wood, it, using addition rare earth alloy element, passes through low frequency electromagnetic oil on the basis of Mg-Zn systems alloy
Sliding semi-continuous casting prepares magnesium alloy ingot blank, then carries out reverse Warm Extrusion and T5 heat treatments.The room temperature tensile mechanical property of material
Can be：390~420MPa of tensile strength, yield tensile ratio ＞ 0.96, elongation after fracture ＞ 7%.
Publication No. CN102828133A Chinese patent application, be by adding rare earth element and strength thermal deformation, it is fast
Fast warm deformation improves the intensity and elongation percentage of magnesium alloy, but the deformation at room temperature ability of alloy still has much room for improvement；Publication No.
CN102392165A Chinese patent application, is, by the cunning semi-continuous casting of electromagnetism, alloy to be improved with reference to reverse Warm Extrusion
Intensity and yield tensile ratio, but the elongation percentage of alloy is still relatively low.It can thus be seen that the plasticity for how being effectively improved magnesium alloy is one
It is individual to be worth deep problem.For wrought magnesium alloy, improved by the control being orientated to magnesium alloy microstructures and texture
Had very important significance with the plasticity for improving wrought magnesium alloy.Specifically by changing magnesium alloy plastic forming side
Formula, such as introduces aximal deformation value detrusion to change the distribution of orientations of basal plane；Another is by introducing after rare earth element
Particle triggered nucleation mechanism, obtains the new crystal grain of orientation randomized distribution, and the texture generated at random can eliminate general deformed Mg
The asymmetric stretching that occurs in alloy, compression drag, are reduced or eliminated the anisotropy of material.Most typical conventional thermal change
Shape processing is single isothermal hot extrusion, but is difficult to less than 10 μm by crystal grain refinement.In conventional research, it is proposed that some are big
The theoretical method of plastic deformation, such as equal channel angular pressing platen press, accumulation rolling and high pressure and torsion etc. are tiny to obtain crystal grain
Microstructure, it might even be possible to reach sub-micron, Nano grade；But these methods are only suitable for preparing small dimension material.Therefore, it is right
The long-term and unremitting effort of vast investigation of materials person is also needed in research and development low-cost and high-performance magnesium alloy.
In summary, room temperature tensile intensity >=420MPa, good elongation percentage >=10% can be obtained by researching and developing one kind；
Tensile strength >=250MPa at 300 DEG C, good elongation percentage >=30% excellent magnesium alloy of comprehensive mechanical property, for meeting state
The fields such as anti-military project, Aero-Space, automobile making are required, are had important practical significance.
