Hi everyone,

Is Anyone has any standard source related to color etching, I have a micro-sample weld specimen of having composition SA 516 Gr70 parent metal, F7P4-EH14 weld metal specifications.

I have to see the microstructure using colour metallography, In which I referred ASM Vol -9 and some other literature but in these literature also only the etchant composition is given, but how to properly etch sample using color etchant is not given.

Can anyone please share some kind of standard flow chart or suggest any standard literature in which I can get to know easily how to proceed and end the etching process.
