Description

A kind of Al, Zn strengthen the high tough heat resistance magnesium alloy of Mg-Sn-RE base
Technical field
The invention belongs to light metal magnesium alloy materials class, relate to the modification of the room-temperature property and the high-temperature behavior of magnesium alloy.
Background technology
Magnesium alloy under the outstanding heavy current social condition of energy-saving and emission-reduction task, will have good application prospects, because in space flight, military project, automobile and other a lot of industries, loss of weight is promptly capable of reducing energy consumption as the lightest structural metallic materials.Simultaneously, also light specific gravity, specific tenacity specific rigidity height, vibration damping and noise reducing ability are strong because magnesium alloy has, liquid condition shaping superior performance and be easy to advantage such as recycling and be described as 21 century " green structured material ".Though magnesium alloy has plurality of advantages, also there are some to limit the weak point of its application.Existing magnesium alloy plasticity and yield strength generally relatively poor (as AZ series and AM series), especially the high-temperature creep resistance of magnesium alloy poor (as Mg-Al system), make magnesium alloy long term operation not surpass in 120 ℃ the environment in temperature, therefore this has just limited magnesium alloy parts and can not use as some heat-resistant parts, has limited the Application of Magnesium scope greatly.Also just for these reasons, now very big enthusiasm has all been poured in the research of high-strength-toughness magnesium alloy and heat resistance magnesium alloy both at home and abroad.
Find had some patents and document to disclose the preparation method and the technology of some high-strength heat-resisting magnesium alloys according to existing patent and literature search." a kind of multicomponent heat-resistant magnesium alloy and preparation method thereof " disclosed as patent CN 101440449A, its composition is designed to Sn:3% ~ 5%, Mn:1.0% ~ 1.5%, Ca:0.9% ~ 1.8%, Ce:0.3% ~ 0.6%, Sc:0.3% ~ 0.5%, Sr:0.08% ~ 0.12%, according to providing example, it is about 180MPa that the process solid solution aging of alloy is handled back room temperature tensile strength, yield strength is about 160MPa, unit elongation is 3% ~ 4%, and the steady state creep speed range is 3 * 10 -8s -1~ 4 * 10 -8s -1Patent CN 101532107A discloses " a kind of heat resisting magnesium-rare earth alloy and preparation method thereof ", its composition is designed to Gd:8% ~ 15%, Y:2% ~ 5%, Sm:0.4% ~ 4.5%, Zr:0.3% ~ 0.7%, Sb:0.3% ~ 2%, according to providing example, it is about 270MPa that the process solid solution aging of alloy is handled back room temperature tensile strength, and unit elongation is 3% ~ 4%.Patent CN 101463441A discloses " rare earth-containing high strength heat resisting magnesium alloy and preparation method thereof ", it is 0 ~ 5% Nd, Si, Sb, Ti, Sn, Sr, Bi, Cd that its composition is designed to Y:3% ~ 16%, Gd:0 ~ 10%, Ca:0.3% ~ 5%, Zr:0.1% ~ 1.5% and one or more content ranges, according to providing example, room temperature tensile strength scope is 170MPa ~ 210MPa under the alloy casting state, and unit elongation is about 5%.These patents provide the heat resistance magnesium alloy with higher-strength, yet also can find out from these patents, present most of high-strength heat-resisting magnesium alloy also has the some shortcomings part, the composition that at first is these alloys is comparatively complicated, and the refractory metal that contains is more, and production technique is poorly controlled, next is to contain the comparatively expensive metallic element of the higher price of content in the alloy, make that the Financial cost increase of alloy is more obvious, though a bit be exactly that the intensity of alloy is higher in addition, plasticity is relatively poor.
In order to reduce the Financial cost of heat resistance magnesium alloy, also there are some that develop not contain the heat resistance magnesium alloy of rare earth now, as Mg-Al-Ca system, Mg-Al-Si system and Mg-Al-Sr system etc.But, according to patent CN 101476072A(heat-resistant deforming magnesium alloy that contains Ca and Sr), CN 1614064A(high-strength creep resistant wrought magnesium alloys that contains Ca and Si) and R. Ninomiya etc. be published in document Improved heat resistance of Mg-Al alloys by the Ca addition(Ca on the Acta metal. Mater to the raising of Mg-Al series magnesium alloy creep property) report, Mg-Al-Ca is in the alloy because form the comparatively thick Mg of size easily 2The phase of Ca and Al 2The Ca phase worsens the alloy room-temperature mechanical property, and higher Ca content makes the alloy casting difficulty simultaneously; Mg-Al-Si is the Mg that has thick man's shape in the alloy structure 2The Si phase, its mechanical property of serious harm makes that it can only be at quick refrigerative extrusion process compacted under; The alloy melting and the teeming temperature requirement height such as AJ52, AJ62 of Mg-Al-Sr system, the die casting difficulty, and be that the AJ52 tensile strength of alloys only is that unit elongation only is about 6% about 150MPa under the common gravitational casting.
In sum, there is the Financial cost height in the heat resistance magnesium alloy of developing now, and moulding process requires harsh, and particularly room-temperature property weak point such as ideal not really makes Application of Magnesium be subjected to restriction in various degree.Therefore, develop the economy height, intensity and plasticity better heat-resisting magnesium alloy can be expanded the Application of Magnesium field to a great extent, have crucial meaning.
Summary of the invention
The objective of the invention is to overcome the weak point of existing heat resistance magnesium alloy, provide a kind of resistance toheat good, a kind of strong plasticity heat resistance magnesium alloy that has higher room-temperature property again simultaneously.In order to realize above purpose, the technical solution adopted in the present invention is: a kind of Al, Zn strengthen the high tough heat resistance magnesium alloy of Mg-Sn-RE base, form by following component by mass percent: 2 ~ 8wt.%Sn, 0.5 ~ 3wt.%RE, 1 ~ 6wt.%M, wherein RE is cheap light rare earths La and Ce, and M is Zn or Al or Zn and Al mixing, and surplus is Mg.
Described strong plasticity heat resistance magnesium alloy is formed for the raw material melting by magnesium ingot, tin slab, aluminium ingot and master alloy Mg-La and Mg-Ce, do not get rid of add other a small amount of alloying element (≤1wt.%), as Mn, Zr, Sb, Si, Sr etc.
