Abstract

The invention relates to a machine manufacturing material, in particular to a high-performance piston manufacturing material. The material contains the following elements in percentage by mass: 11.0 to 13.0 percent of Si, 2.8 to 3.6 percent of Cu, 2.0 to 2.6 percent of Ni, 0.8 to 1.2 percent of Mg, 0 to 0.7 percent of Fe, 0.05 to 0.2 percent of Ti, 0 to 0.3 percent of Mn, 0.05 to 0.2 percent of Zr, 0.05 to 0.18 percent of V and the balance of Al. By proportioning the chemical components of the conventional piston manufacturing material more reasonably, the piston manufacturing material has qualitative leap; and compared with the conventional similar products, the piston manufactured by using the material has more excellent high-temperature mechanical strength, tensile strength and fatigue resistance and higher thermal stability and hardness, and meets various strict requirements of the conventional engine on the piston.

Description

High-performance piston manufactured materials
Technical field
The present invention relates to a kind of machinofacture material, refer in particular to a kind of high-performance piston manufactured materials.
Background technology
Piston is called as the heart of engine, and it is one of most important component in the engine, and its effect is to bear gaseous tension, and passes to connecting rod by wrist pin and order about crankshaft rotation.The Working environment of piston is very abominable, and piston must bear high temperature, highly compressed thermal load and very high mechanical load.Therefore, piston is as a very important member that transmits energy in the engine, and its material must possess following performance: density is little, light weight, heat conductivity is good, thermal expansivity is little, have enough high-temperature machinery intensity, wear-resisting, corrosion-resistant, dimensional stability is good.Growing along with engine technology can not have been satisfied the design requirements of engine high-performance low emission with the piston of existing conventional piston manufactured materials manufacturing, therefore need develop the manufacturing that the high performance piston material that makes new advances is used for piston.
Summary of the invention
The technical problem to be solved in the present invention is: disclose a kind of high-performance piston manufactured materials, compare with existing like product with the piston that this material produces, have higher high-temperature machinery intensity, tension fatigue resistance, thermostability and hardness, more can meet present engine every harsh requirement that piston proposed.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high-performance piston manufactured materials, and the quality percentage composition that contains following element and each element in the material is:
Si 11.0~13.0%
Cu 2.8~3.6%
Ni 2.0~2.6%
Mg 0.8~1.2%
Fe 0~0.7%
Ti 0.05~0.2%
Mn 0~0.3%
Zr 0.05~0.2%
V 0.05~0.18%
Surplus is Al.
Piston manufactured materials of the present invention, the content of Cu element is compared with existing piston manufactured materials to some extent in the material increases (the Cu constituent content is 0.8~1.3% in the existing piston manufactured materials), the existence of Cu element not only can improve the machinability of alloy material and the smooth finish on surface, the more important thing is the high-temperature machinery intensity that can improve alloy material, but simultaneously, the content of Cu element also can not be too much, cross the castability variation that can make alloy material at most, corrosion resistance nature reduces, therefore its content must transfer to one as far as possible in the ideal scope, promptly under the prerequisite of castability that guarantees alloy material and corrosion resisting property, make full use of the high-temperature machinery intensity that alloy material usually improves in Cu unit.
Piston manufactured materials of the present invention, the content of Ni element is compared with existing piston manufactured materials also in the material increases to some extent (the Ni constituent content is 0.8~1.3% in the existing piston manufactured materials), the increase of Ni constituent content also can improve the high-temperature machinery intensity of alloy material in the alloy material, improves the thermostability of alloy material simultaneously.
The Mg element also is the important element that improves alloy strength in the alloy material, can further improve alloy stability when especially it is used in combination with the Cu element, but it equally also can not add too much, easily forms crisp phasic property when the Mg constituent content is too much on crystal boundary, also may cause the casting slag inclusion.
Piston manufactured materials of the present invention, the content of Mn element is compared with existing piston manufactured materials also in the material increases to some extent (the Mn constituent content is 0~0.15% in the existing piston manufactured materials), the existence of Mn element can improve thermostability, creep rupture strength and the hardness of alloy material, can also reduce simultaneously the harm of impurity element iron, but can not add equally too much, Mn element add-on is excessive then can to form thick frangible compounds.
The invention has the beneficial effects as follows: by the chemical ingredients of existing piston manufactured materials is carried out more reasonably proportioning, make the piston manufactured materials that qualitative leap arranged, piston with this material manufacturing is compared with existing like product, have more outstanding high-temperature machinery intensity, tensile strength, fatigue resistance, higher thermostability and hardness more can meet present engine to every harsh requirement that piston proposed.
