Abstract
The invention discloses a metallurgical method of metal-based nanometer composite material, which comprises the following steps: preparing metal particle or block; adopting heat penetrating method to prepare nanometer composite particle or metal nanometer block through diamond or ceramic nanometer powder; setting the metal quantity at 5-80% in the fusing furnace; smelting evenly; discharging. The invention possesses high extending strength, fatigue strength and hardness.
Description
Technical field
The present invention relates to a kind of smelting process of matrix material, specifically relate to a kind of smelting process of metal-base nanometer composite material.
Background technology
Entered since 21 century, human is to solve energy problem, environmental issue, and the utilization of resources problem, and satisfy IT industry, sciemtifec and technical spheres such as biotechnology especially to the demand of nanometer and nano composite material, have dropped into huge man power and material to novel material.But can only produce the nano combined and metal-base composites of powdery or biscuit metal at present.Nano combined and the metal-base composites of bulk metal also is not developed into.Limited the application of metal nanometer composite material at a lot of key areas.
Summary of the invention
Purpose of the present invention provides a kind of method of producing the bulk metal based nano composite material.
The technical scheme that adopts is:
The smelting process of metal-base nanometer composite material comprises the following steps:
A, make the compound fritter of metal nano composite particles or metal nano earlier;
The metallic substance that needs are smelted is made particle or fritter, be installed in the heat treatment furnace, and be embedded in diamond or the ceramic nano powder, make metal nano composite particles or the compound fritter of metal nano by the thermoosmosis method, standby;
B, make the bulk metal nano composite material
Smelting when making the identical metal of above-mentioned metal nano composite particles or the compound fritter of metal nano; add Manufactured metal nano composite particles or the compound fritter of metal nano in stove according to the weight percent of metal smelting total amount 5 ‰ to 80%; stir; smelting process is smelted routinely, is nano composite after coming out of the stove.
Also can be with metal powder such as iron powder and diamond nano powder according to respectively accounting for evenly back cold-forge forming of 49-50% to 51-50% mixed, then under 723 ℃-1800 ℃ temperature, the nano composite fritter is formed in the powder mix refining, smelt in the smelting furnace of general carbon steel according to 0.5 ‰ to 80% weight percent adding then, smelt routinely and come out of the stove, be metal nanometer composite material.
The metal or alloy that adopts the inventive method to produce, more former trade mark metal or alloy has special microtexture and higher draw tensile strength, fatigue strength and hardness.Therefore, improve performances such as wear resistance, erosion resistance, anti-mechanical shock and thermal shocking greatly, had application prospect widely.
Embodiment
Embodiment one
The smelting process of metal-based nano material is:
A, particulate state or fritter steel 16Mn cleaning is clean is installed in the heat treatment furnace, and is covered by nano-diamond powder, carries out thermoosmosis.Oozing the nano-diamond powder temperature should be in the austenitic area, promptly should be at Fe-Fe
3More than the C-S-E line in the C phasor, below the N-J-E line, this moment, iron was r iron, was face-centered cubic lattice and diamond has affinity.Infiltration general t of nano-diamond powder hold-time 〉=4 hours.
B, when smelting the 16Mn steel, Manufactured nanometer 16Mn particle or the fritter of smelting 16Mn gross weight 0.5 ‰ to 80% joined in the smelting furnace, to be mixed coming out of the stove after evenly gets final product.
Embodiment two
The smelting process of metal-base nanometer composite material is:
A, with ZL101AT6 particle or fritter, be placed in the heat treatment furnace, and be embedded in the nano alumina powder, use the method identical to make nanometer ZL101AT6 particle or fritter with embodiment one.
B, in smelting the ZL101AT6 process, will add above-mentioned Manufactured nanometer ZL101AT6 particle or fritter in smelting furnace by smelting total amount 0.5 ‰ to 80% weight percents, mixingly come out of the stove after evenly, be finished product.
Embodiment three
The smelting process of metal-base nanometer composite material is:
A, the iron powder with 50% and 50% diamond nano powder mix the back cold-forge forming, behind 723-1000 ℃ temperature sintering, promptly make nano composite material.
B, when smelting carbon structural steel, in smelting process, in the smelting furnace liquation, add the above-mentioned nano composite material of making of metal smelting total amount 0.5 ‰ to 80%, come out of the stove after the melting evenly, be finished product.
Claims (1)
1, the smelting process of metal-base nanometer composite material, it is characterized in that metallic particles or slug, be placed in the heat treatment furnace, and cover with diamond nano powder or ceramic nano powder, by thermoosmosis, the infiltration temperature should be in the austenitic area, and the compound fritter of metal nano composite particles or metal nano is made in penetration time t 〉=1 hour; Again the metal nanometer composite material of making is joined in the smelting furnace liquation by the weight percent of smelting identical trade mark total metal content 0.5 ‰ to 80%, come out of the stove after the melting evenly, be finished product.
