Aluminous / heterogeneous metal structure can produce steel adequately the respective advantage of different material, have light qualitative, excel in and performance of good heat conduction electric conduction, and good economic benefits, make in aerospace, shipping, car waited for a domain to be paid close attention to extensively, showed good applied prospect. Aluminous / steel is heterogeneous the main problem that the metal solders is both the solid dissolve between spends difference of function of very low, hot physics big, both between the compound between the metal that extremely easy reaction makes brittleness, metallic compound grows rate is very rapid, control is undeserved will bestrew whole connect; At the same time the compound between the metal shows intense stress to amass the liability, can bring about contact rapid brittleness ruptures, the mechanical function of serious exasperate connect, this already was become solder the research heat of the domain and difficulty problem. In recent years, a lot of scholars had thorough research to the join of aluminium and steel, involve almost solder all sorts of methods of the domain, include drill rod solder, press solder and fusion welding to wait, but no matter which use to plant,solder method, solder high grade to obtaining connect had stuff crucial action, so, development goes can apply to aluminium / steel is heterogeneous what the metal solders is special solder material is a very main job. The article elaborated the basic principle that adds alloying element in detail, induced solder in the light of what differ method, analysed alloying element to improve aluminium / the action of steel connect function, developed foreground to make to its look into. The basic principle that adds alloying element is aluminous / steel is heterogeneous the metal solders in the process, solder the action with the crucial move since material. Normally, aluminous material, rolled steel, solder the metallographic organization of material all does not belong to same sort model, solder the inhomogenous sex of the easy generation is serious metallographic organization in contact, chemical composition and mechanical function and had appeared to solder greatly leftover stress, liquid state is aluminous at the same time base the compound between the metal that solder and steel reaction still can make brittleness, serious aggravation is aluminous / the function of steel connect, this is with respect to the requirement in aluminium radical solder add special alloying element in order to improve its performance. Choose and add the principle with have certain normally and requirement of special alloying element. CNC Milling CNC Machining
