Abstract
The invention discloses a kind of dyeing etchant of martensite transformation tissue in display S30432 boiler tubes, the etchant mixes according to the following formulation, sodium pyrosulfite Ag, the hydrochloric acid BmL of volumetric concentration 10%, wherein, A：B=(0.25 1)：(90‑110).The cenotype martensite transformation close to crystal boundary area can be appeared clearly from the S30432 boiler tubings of the etchant etch configured through the present invention, the martensite transformation tissue in light microscope rapid examination sample can be used, and avoids using transmission electron microscope observing.
Description
Technical field
The invention belongs to Metallographic Analysis technical field in steel, and in particular to one kind shows phase transformation horse in S30432 boiler tubes
The dyeing etchant of family name's body tissue.
Background technology
In room temperature texture after S30432 boiler tube high-temperature services often occur close to grain boundary area it is a small amount of mutually covert
Become martensitic structure, had a strong impact on the room-temperature mechanical property and corrosion among crystalline grains of S30432 boiler tubes, at present with routine
It can not be observed after chloroazotic acid etchant etch with light microscope, complicated sample preparation transmission electron microscope observing can only be passed through.
The content of the invention
It is an object of the invention to solve above technical problem, there is provided one kind shows phase transformation geneva in S30432 boiler tubes
The dyeing etchant of body tissue.
To reach above-mentioned purpose, the present invention is achieved by the following technical solutions：
The dyeing etchant of martensite transformation tissue in a kind of display S30432 boiler tubes, the dyeing etchant by matching somebody with somebody as follows
Side mixes：Sodium pyrosulfite Ag, the hydrochloric acid BmL of volumetric concentration 10%, wherein, A：B=(0.25-1)：(90-110).
Further improve of the invention is that the dyeing etchant mixes according to the following formulation：Sodium pyrosulfite Ag,
10% hydrochloric acid BmL, wherein, A：B=0.5:100.
Compared with prior art, the present invention has the advantage that：
The dyeing etchant that the present invention configures can easily with showing martensite transformation tissue in S30432 boiler tubes,
Safe operation, simple, cost is cheap, pollution-free.
Sample after processed by the invention, martensite transformation tissue can be appeared clearly from, can quickly be seen with light microscope
The martensite transformation tissue in sample is examined, and avoids using transmission electron microscope observing.
Brief description of the drawings
Fig. 1 is the metallograph after S30432 high-temperature service sample chloroazotic acid etches；
Fig. 2 is that S30432 high-temperature services sample uses the metallograph after etchant etch of the present invention.

Embodiment 4：
The dyeing etchant of martensite transformation tissue in a kind of display S30432 boiler tubes of the present invention, the etchant is by as follows
Formula mixes, sodium pyrosulfite：10% hydrochloric acid of volumetric concentration=0.25g：110ml.
The material used in case study on implementation of the present invention is ASME SA213S30432 high-temperature service samples, and its chemical composition is shown in
Table 1.
Table 1：The chemical composition (wt%) of case study on implementation S30432 steel
First by chloroazotic acid etchant, to sample, according to DL/T 884-2004, " thermal power plant's metal lographic examination is led with assessment technology
Method in then " carries out etch, and Fig. 1 is shown in obtained metallographic structure, then carries out etch to sample using etchant of the present invention, obtains
To metallographic structure see Fig. 2.Contrast visible, after chloroazotic acid etched samples, it is organized as austenite+a small amount of granular carbonization
Thing, after etchant etch of the present invention, its organize in it is high-visible close to grain boundary area be in salmon pink-martensite transformation group
Knit.
