Abstract
The invention provides a nano TiN modified TiC-based steel bond hard alloy which consists of TiN, TiC, Ni power, Mo, MnFe, Cr, C, Fe and inevitable impurities, wherein the content of impurities in the whole alloy is less than or equal to 30%. According to the invention, a power metallurgy method is adopted, and the steel bond hard alloy is prepared by mixing material in a wet-milling way, filtering and drying, pelletizing glue and pelletizing, compressing and molding and vacuum sintering. The steel bond hard alloy is wider in use range, can be not just made into a composite material by means of imbedding, inlaying and welding-on, can be independently used for a structural member wear-resistant material, is longer in service life, and is more prominent in energy-saving effect.
Description
Technical field
The invention discloses a kind of nano TiN modified TiC base Steel Bond Hard Alloy, it be a kind of high-intensity can be as the high-wearing feature material of structural part, but castingin, welding-on or be set into composite abrasion resistance material. belong to the powder metallurgy preparing technical field.
Background technology
TiC base Steel Bond Hard Alloy is characterized in light specific gravity (density is low in other words), and hardness is high, and wear resistance is good, is widely used as the structural part material by field of engineering technology, castingin, is set into composite abrasion resistance material etc.But this material is when strong bump high firmness material, and the intensity that seems and toughness are not enough, the time fracture and the generation of fragment situation are arranged, bad like the weldprocedure processing, micro-flaw can appear, will produce fragment in the use.In addition, make this alloy material at present both at home and abroad, still adopting is traditional alloy formula; Strengthen with the nickel molybdenum bullion content of expensive and to mend toughly, sinter alloy blank into, again through the tough processing of water or forge thermal treatment with traditional powder metallurgical technique; Be machined to high-abrasive material; Adopt this technology cost very high, and yield rate is not high yet, has caused the waste of resource.
Summary of the invention
Technical problem to be solved by this invention provides a kind of nano TiN modified TiC base Steel Bond Hard Alloy, can improve the intensity and the toughness of TiC base Steel Bond Hard Alloy greatly, and practice thrift cost.
The technical scheme that problem adopted that the present invention will solve is:
A kind of nano TiN modified TiC base Steel Bond Hard Alloy consists of: TiN0.5%～2.0%, TiC43%～49.5% by mass percentage; Ni powder 1.0%～1.8%, Mo powder 0.8%～1.5%, MnFe powder 8.0%～13.0%; Cr0.1%～0.2%; C0.5%～2.0%, surplus are Fe powder and unavoidable impurities thereof, and content≤0.3% of impurity in whole alloy.
As preferably, a kind of nano TiN modified TiC base Steel Bond Hard Alloy of the present invention consists of: TiN1.5% by mass percentage; TiC46.5%, Ni powder 1.6%, Mo powder 1.2%; MnFe powder 11%, Cr0.2%, C0.9%; Surplus is Fe powder and unavoidable impurities thereof, and content≤0.3% of impurity in whole alloy.
A kind of nano TiN modified TiC base of the present invention Steel Bond Hard Alloy adopts powder metallurgy process, through wet-milling batch mixing, filtering drying, mix glue granulation, compression moulding, vacuum sintering and process Steel Bond Hard Alloy.
Characteristics of the present invention: TiC and TiN have the old sodium-chlor type crystal structure of F.C.C. point, and can form continuous solid solution according to (Hume Rothery) rule in the Xiu Moluosai.And their temperature of fusion (TiC is 3430k; TiN is 3220k) very close; Unit cell parameters (TiC is 0.4322nm, and TiN is 0.4242nm) is also very close, so the C atom in the Ti dot matrix can be substituted with any ratio by the N2 atom; Form a kind of continuous solid solution, i.e. TiC (C1-xNx) (0≤x≤1).In general with the increase of x value, the hardness of material reduces, and toughness improves.This shows through control x amount just the amount of TiN to improve toughness and do not reduce hardness be feasible.
It is nano modification that another of this research strengthens the tough mechanism of benefit, and the effect it is generally acknowledged has three kinds.
(1) grain refining effect adds the nanometer particle in micron order hard phase TiC, can improve into nuclear concentration.When reducing grain-size, promote homogeneous grain sizeization, this control grain growth also makes the microstructure of uniform crystal particlesization, helps improving the bending strength of material.
(2) " intracrystalline type " structure function in the nano-micrometre matrix composite, because particle size exists the difference of the order of magnitude, can reduce sintering temperature.So in certain temperature, blapharoplast is that karyomorphism becomes crystal grain with the nano particle, nano particle is wrapped in the blapharoplast, form " intracrystalline type " structure.Crystal boundary in this structure between blapharoplast is called oikocryst circle; Crystal boundary between nanometer and blapharoplast is called time crystal boundary or cries time interface, and the effect of this interfacial effect has weakened the effect of crystal boundary, brings out transgranular fracture; Suppress the dislocation motion in the breaking-down process, thereby improve intensity.
(3) the intercrystalline potential nano effect of micron; Because the bigger unrelieved stress of inferior existence at the interface between nanometer and micron particle; Make matrix grain produce a large amount of subgrain boundaries, the generation of this subgrain boundary makes matrix refinement more, and makes matrix grain be in a kind of potential differentiation state; People call " nano effect " to this state, thereby further improve intensity.Another research thinks that tough effect is mended in the enhancing of material behind the nano modification and changed fracture mode, because nanometer can the absorption portion energy-to-break in the process that stops dislocation motion, breaking point played " pinning " effect and improves intensity.
Research and development are with the meaning that nano TiN improves the Steel Bond Hard Alloy performance: the first makes the use range of Steel Bond Hard Alloy more extensive; Promptly both be not limited to castingin, inlayed, welding-on becomes matrix material, also can be used for the structural part high-abrasive material separately, and work-ing life can be longer; Make energy-saving effect more remarkable; The bending strength of alloy is brought up to more than the 2000MPa by 1600MPa, and hardness does not need thermal treatment just can reach HRc>=62, density≤6.2g/cm
3, product percent of pass is brought up to more than 98% from 95%.
