Abstract
The present invention provides a kind of IF steel metallographic etching agent, it is made of hydrochloric acid, iron chloride and pure water, wherein content of hydrochloric acid is 10%~40%, iron chloride 4%~12%, remaining is pure water, after above-mentioned several material mixings, corrosive agent is can obtain after filtering out precipitation, the IF steel curved beams that will be prepared, wipe 3~5S, you can obtain clearly IF steel metallographic structure with corrosive agent at normal temperatures.Metallographic etching agent provided by the invention, etching time is short, and corrosion step is simple, easy to operate.
Description
Technical field
The invention belongs to IF steel metallographic observation technical fields, are related to a kind of metallographic etching agent suitable for IF steel.
Background technology
IF steel, i.e. gapless atomic steel, sometimes referred to as ultra-low-carbon steel, have extremely excellent deep drawability, are widely used in vapour
Car, household electric appliances.In actual production, a small amount of Ti, Nb element is usually added, to C, N interstitial atom in fixed steel, is formed
Carboritride, so as to obtain the pure ferritic steel of gap-free atom.
Since IF steel is purer, metallographic structure is pure ferritic structure, and the interstitial atom of grain boundaries noresidue, leads
Cause IF steel to hardly result in clearly tissue topography with low-carbon ferritic steel metallographic etching agent nital, therefore give scientific research work
The Metallographic Analysis of author causes very big difficulty, and then influences the development progress of the variety steel.
Patent CN 102890027A disclose a kind of " gapless atomic steel flat cold-rolled sheet metallographic structure display side containing Ti
Method ", the patent are polished first with a certain proportion of ethanol solution, then respectively with the first corrosive agent and the second corrosive agent into
Row corrosion, the metallographic structure for the gapless atomic steel containing Ti that can be cleaned；Patent CN 1167257A disclose that " cold rolling is moved back
Fiery gapless atomic steel method for displaying metallographic structure ", the patent first with nitric acid alcohol corrode, then with contain Sodium Metabisulfite,
The corrosive agent 2 of sodium thiosulfate carries out anticaustic, then rinses, cleans light blue top layer, can obtain clearly metallographic structure.
Two above patent can clearly show IF steel metallographic structures, but need to configure two kinds of corrosive agent, and corrosion step is cumbersome, real
In the operation of border, the failure of any one process can all produce unsharp metallographic structure, and larger work is brought to metallographic sample preparation
Amount.
The content of the invention
It is an object of the invention to provide a kind of IF steel metallographic etching agent, and the metallographic etching agent etching time is short, corrosion step
It is rapid simple, easily control, after corrosive agent corrosion, clearly metallographic structure can be obtained, preferably facilitate vast scientific research
Worker.
To achieve these goals, present invention employs following technical scheme：
A kind of IF steel metallographic etching agent, is made of hydrochloric acid, iron chloride and pure water, and the mass percent of each component is as follows：
Hydrochloric acid (mass percent concentration 37%)：10%~40%；
Iron chloride：4%~12%；
Remaining is pure water.
The preparation method of above-mentioned metallographic etching agent：First by hydrochloric acid and pure water after mixing, iron chloride is added, stirred
All dissolvings, finally filter out the precipitation in solution, the solution after filtering is IF steel metallographic etching agents.
The IF steel curved beams that will be prepared, wipe under room temperature and rinse specimen surface with clear water after 3~5S, can be carried out after drying
Observe metallographic.
Compared with the prior art, the present invention at least has the advantages that：
Metallographic etching agent etching time provided by the invention is short, and corrosion step is simple, easy to operate, after excessive erosion, energy
Access clearly metallographic structure.
Brief description of the drawings
Fig. 1 is IF steel nitric acid alcohol corrosive agent metallographs；
Fig. 2 is corrosive agent metallograph of the present invention.
Embodiment
Comparative example 1
Fig. 1 is the metallographic obtained after sample wipes in 4% nital, and the ferrite grain boundaries of the figure obscure not
Clearly.
Embodiment 1
By 100ml pure water, 15ml mixed in hydrochloric acid, 10g iron chloride is added, it is heavy in solution to be filtered out after stirring evenly
Form sediment, the solution after being filtered, by IF steel by conventional edge sample, after corase grinding, fine grinding, polishing, with the corrosive agent pair under room temperature
Sample wipes 3~5S, you can observation obtains clearly IF steel metallographic structure.
Embodiment 2
By 150ml pure water, 40ml mixed in hydrochloric acid, 15g iron chloride is added, it is heavy in solution to be filtered out after stirring evenly
Form sediment, the solution after being filtered, by IF steel by conventional edge sample, after corase grinding, fine grinding, polishing, wipes sample with the corrosive agent
Wipe 3~5S, you can observation obtains clearly IF steel metallographic structure.
Embodiment 3
By 110ml pure water, 10ml mixed in hydrochloric acid, 5g iron chloride is added, the precipitation in solution is filtered out after stirring evenly,
Solution after being filtered, by IF steel by conventional edge sample, after corase grinding, fine grinding, polishing, 3 are wiped with the corrosive agent to sample
~5S, you can observation obtains clearly IF steel metallographic structure.
Embodiment described above only expresses the embodiment of the present invention, but can not be therefore understands that for the present invention
The limitation of the scope of the claims.Any variation that those skilled in the art is the present invention under the enlightenment of present inventive concept falls
Within the scope of the present invention.
