Description
Technical field
The present invention relates to a kind of Steel Bond Hard Alloy, particularly a kind of TiC is Steel Bond Hard Alloy.
Background technology
Steel-bonded carbide is as a kind of new engineering material, and its excellent properties between tool steel and Wimet and can processing and good heat treatment characteristic makes it in manufacturing application, more and more receive material supplier author's concern.In recent years, the composition range of Steel Bond Hard Alloy is constantly widened, and in alloy, steel matrix content was generally 50%～75% in the past, forward both end extension, and one is extended to Wimet field, improves hard phase content, reaches as high as 92%; Extend to rapid steel field other end, improves steel matrix content, reaches as high as 90%.By selecting different steel grades and composition, make binding agent, can produce the alloy with specified property, to adapt to the requirement in various different application field, Steel Bond Hard Alloy range of application is constantly expanded, in precision die, wear part and mine instrument, fragmentation, all well applied, market share amount is also increasing.W, Co are as rare elements simultaneously, face more and more severeer scarcity of resources, and the main hard phase that TiC is steel-bonded carbide be TiC, main bonding be Fe mutually, have very large resources advantage, this is also that TiC is one of steel-bonded carbide reason of being more and more used widely.
TiC is that steel-bonded carbide is mainly used in the fields such as mine instrument, engineering machinery, and its main component is TiC, MnFe, Ni, Mo and Fe.As patent " TiC is Steel Bond Hard Alloy and preparation method thereof " (CN 102230119 A) discloses the preparation method that a kind of TiC is Steel-bonded Cemented Carbide, its composition and weight percent are: hard phase TiC(50.0～70.0) %, high mangaenese steel Binder Phase (30.0～50.0) %, wherein Mn(4.2～7.2) %, Ni(1.0～2.0) %, Mo(0.5～1.0) %, Cr(0.5～1.5) %, C(11～14) %, rare earth (0.05～0.15) %, iron is surplus.This alloy type is similar to conventional high mangaenese steel Steel Bond Hard Alloy, has higher hardness and wear resistance, but alloy finally can not obtain uniform austenite completely, and the performance of high mangaenese steel matrix fails well to be embodied, and affects the shock resistance of alloy.
Summary of the invention
For above-mentioned deficiency, the object of this invention is to provide that a kind of wear resistance is higher, shock resistance can better TiC be Steel Bond Hard Alloy.
TiC provided by the invention is Steel Bond Hard Alloy, and its each composition and weight percentage are: Ti 47.5～56%, and Mn 6.4～8%, and Ni 2.0～4.0%, and Mo 0.6～1.0%, rare earth element 0.3～0.5%, and C 11.6～13.5%, and surplus is Fe.
Described rare earth element is Y, Ce or La.
Described TiC is the preparation method of Steel Bond Hard Alloy, comprise that batching, ball milling, spraying are dry, compression moulding, sintering, each raw material of described batching and weight percentage are: TiC powder 60～70%, ferromanganese powder 8.0～10.0%, Ni powder 2.0～4.0%, Mo powder 0.6～1.0%, rare earth element 0.3～0.5%, surplus is iron powder.
As improvement, above-mentioned sintering be take zirconium white boat as contact material, at 1400～1420 ℃ of sintering.
TiC of the present invention is that Steel Bond Hard Alloy hard phase is TiC, and ratio is 60～70wt%; Bonding is high mangaenese steel mutually, bonding middle Mn 6.4～8% mutually, and Ni 2.0～4.0%, and Mo 0.6～1.0%, rare earth element 0.3～0.5%, surplus is Fe.
Publication No. is the patent of invention of CN 102230119 A, in its alloy, contain higher Mo and Cr, and Mo and Cr all add with the form of non-carbide, incorporate matrix in alloy production process in, form intermetallic compound, because Mo, Cr dwindle austenitic area element, can make alloy finally can not obtain uniform austenite completely.And adding of Mo of the present invention is a small amount of, and there is no Cr, object is to improve alloy in heat treated thermal conductivity, improved the content of Mn, Ni in alloy simultaneously, Mn, Ni are the expansion elements of austenitic area, the raising of its content has guaranteed that matrix can obtain comparatively completely at normal temperatures, austenite structure, and the ratio of Mn, C content in matrix (high mangaenese steel) that guarantees uniformly reaches 10:1 left and right effectively, makes it effectively embody the performances such as shock resistance of high mangaenese steel.
In addition, Ni content improves the raising that also helps alloy strength and weldability, and the trend that alloy product is cracked when casting, welding reduces.By improving the content of rare earth element (Y, Ce or La), comparatively obviously improved the wettability between Ti-Fe, the densification degree of alloy is improved, porosity declines.
TiC of the present invention is that the TiC particle of Steel Bond Hard Alloy presents a large amount of irregular polygons, and actual cut, the broken effect of cutter are more outstanding, and internal organizational structure is even, and wear resistance is improved, and bending strength is better, is out of shape littlely, and dimensional precision is high.
