background of invention
Steel Bond Hard Alloy (hereinafter referred to as steel-bonded carbide) take steel as matrix, wolfram varbide, titanium carbide etc. be hard phase adopt powder metallurgy process to produce between Wimet and the high life moulding stock between alloy tool steel, die steel and rapid steel and engineering materials.The ratio range of steel-bonded carbide steel matrix Binder Phase and hard phase is quite extensive, and this just determines it and possesses following excellent properties: 1) processing performance widely, mainly can forgeability and machinable performance and heat-treatability and weldability.2) good physical and mechanical properties, is mainly manifested in the wear resistance suitable with high-cobalt hart metal; Rigidity high compared with steel, Young's modulus, bending strength and ultimate compression strength; Toughness high compared with Wimet; And good self lubricity and high damping characteristic etc.3) excellent chemical stability, as high temperature resistant, anti-oxidant, anti-various dielectric corrosions etc.Due to the over-all properties of the above-mentioned excellence of steel-bonded carbide, make it in tool die material, wear part, high temperature resistant and corrosion resistant member material etc., more and more occupy consequence, and be used widely in fields such as intermetallic composite coating, five metals electronics, automobile, machinery, metallurgy, chemical industry, boats and ships, aerospace and nuclear industry and obtain good result.As compared with alloy tool steel, die steel and rapid steel, steel-bonded carbide can make die life number increase substantially with ten times of ground, and economic benefit is also very remarkable.
Wolfram varbide steel-bonded carbide compared by titanium carbide Steel Bond Hard Alloy, and its cost is low, is applicable to marketing and uses.But the obdurability of its alloy is still lower, far can not meets more and more many power that withstands shocks comparatively large, use when in the higher situation of impact velocity.Therefore the titanium carbide Steel Bond Hard Alloy of Development and Production high-performance, low cost is necessary.Wherein, the obdurability improving titanium carbide steel-bonded carbide is the research direction of emphasis.
At present, the method mainly powder metallurgy lqiuid phase sintering method of TiC Steel Bond Hard Alloy is prepared.Lqiuid phase sintering method can need to select suitable Binder Phase according to practical application and can adjust the content of hard phase in a big way, but due to the hard phase add mode introducing in addition usually of powder metallurgy lqiuid phase sintering method, material cost is high, particle is thick, the wettability of hard phase titanium carbide and Binder Phase is bad, interface vulnerable to pollution etc., therefore it is high that the Steel Bond Hard Alloy prepared by lqiuid phase sintering method has porosity, performance is low, high in cost of production shortcoming, for requiring that higher application scenario often needs through forging or hip treatment, the cost performance of material reduces further.
In recent years, the research that employing in-situ synthesis prepares Steel Bond Hard Alloy has been carried out both at home and abroad.Situ synthesis techniques is a kind of by alloy designs, and under certain condition, in matrix metal, reaction in－situ generates the advanced composite material technology of preparing of one or more thermodynamically stable hard phases.Compared with traditional material preparation method, this technology has that preparation technology is simple, the wild phase of produced in situ is not contaminated, interface bond strength high, is the trend of Steel Bond Hard Alloy technology of preparing development.
But in-situ synthesis also has many deficiencies: enhanced granule is only limited to the thermodynamically stable grain in particular substrate; Comparing of generating is complicated, wayward; Granular size, shape are by the kinetic control of forming core, growth process; and after in-situ particle formed; often segregation gap or grain boundary can be asked in dendrite in castingprocesses; detrimentally affect is produced to material structure and performance; and manufacturability is poor; preparation cost is higher than existing technique, is unsuitable for large-scale production.Obviously, the key that situ synthesis techniques realizes industrialization must study rational homogenization process further, optimum synthesis technique, reduction production cost.
