Description
Technical field
The invention belongs to the technical field of rotten aluminum base alloy, specially refer to the technology that changes the aluminum base alloy physical structure by hot-work.
Background technology
The hypereutectic al-si that adopts low density, high abrasion is that traditional motor car engine, compressor cast iron and the steel casting of alloy components replacement is the target that the investigation of materials worker pursues for many years.Transcocrystallized Al-Si alloy has characteristics such as thermal expansivity is low, density is little, thermal conductivity is good, wear-resisting, anti-corrosion because of it, be particularly suitable for making the light wear-resistant component, so, especially in automotive industry, be widely used in fields such as Aeronautics and Astronautics, communications and transportation, mechanical workouts.Yet, traditional prepared hypereutectic Al-Si of ingot metallurgy technology is an alloy, the mutually thick popularization that limits its application of its primary silicon, though adopt the method for refinement primary silicon, but it is very limited to casting brilliant thinning effect, and using this method that the element silicon add-on is restricted, the wear resisting property of alloy is difficult to be improved.
Contradiction between the appearance of flash set technology and development can partly solve the element silicon add-on and primary silicon be mutually thick, but flash set technology complex technical process and manufacturing cost are too high, have limited its practical application, the particularly application in civil area.In addition, also can obtain to have thin crystalline substance and high-volume fractional second aluminium alloy of element silicon mutually with the manufacturing process of matrix material, but compounding technology equally also has complex process, cost height, and the even phase interface of the second phase skewness is in conjunction with problem such as bad.
Summary of the invention
The present invention is directed to the problems referred to above of the aluminium alloy existence that contains high silicon, proposed a kind of heat-resisting, attrition resistant silumin and corresponding moulding process.Purpose of the present invention not only will be sought a kind of good wear resistance and higher stable on heating new alloy of having concurrently, and will propose a kind of new approach mutually for the refinement alloy strengthening.
Wear-resisting, heat-resisting silumin proposed by the invention is characterized in that the chemical ingredients (percentage ratio calculating by weight) of alloy is silicon (Si): 15～20; Iron (Fe): 2.0～5.0; Manganese (Mn): 1.0～3.0; Copper (Cu): 1.0～4.0; Magnesium (Mg): 0.5～1.5; Nickel (Ni): 1.0～3.0; Aluminium (Al) is surplus.
The invention allows for a kind of and above-mentioned alloy and make the alloy shaping process that component adapt, it is characterized in that silumin is adopted the semi-solid state extrusion molding after melting.
The whole process of above-mentioned moulding process is: adopt conventional aluminium alloy casting melting technology earlier, through casting ingot-forming after the melting.Adopt machining process to make its size reach the requirement of extrusion mould on ingot casting.The extrusion ingot that machining is good (billet) carries out second-heating to be handled, Heating temperature is determined according to alloying constituent, when the liquid phase volume in the billet reaches 20～40Vol%, to be in semi-solid billet and put into extrusion mould, set the working parameter of extrusion machine, finally extrusion molding in mould according to the specification of component.After the parts of extrusion molding passed through solid solution and ageing treatment again, wear resisting property was good, and mechanical property also is greatly improved.
By metallurgical analysis, the tissue of discovery silumin after the semi-solid state extrusion molding compared with as-cast structure significant variation taken place, thick rich iron phase disappears and is converted into the comparatively near granular phase of rounding, the size of silicon phase generally diminishes and roundingization, the big silicon of discrete occurs and also trend towards being spherical mutually, this should be the reason that semi-solid state moulding component performance improves.
Wear-resisting, Heat-resistant High-silicon Aluminum Alloy And Its Forming Process provided by the present invention has the following advantages mutually on year-on-year basis with existing silumin and moulding process:
1, new alloy of the present invention has good wear resistance and thermotolerance;
2, moulding process of the present invention, technology is simple, and cost is low, has solved the expensive problem of flash set technology and composite material manufacturing technology, will widen the Application Areas that contains high-silicon abrasion resistant, heat-resisting silumin greatly;
3, its metallographic structure of parts with alloy of the present invention and technology manufacturing has obvious variation, and its comprehensive mechanical performance is greatly improved.
