Martensite will be dark and the ferrite will be coloured: HCl: 1,5 grams: Ethanol: 33 ml: Kalling’s No:2: CuCl2: 5 grams: Immersion etching at 20° C

Martensite will be dark and the ferrite will be coloured: HCl: 1,5 grams: Ethanol: 33 ml: Kalling’s No:2: CuCl2: 5 grams: Immersion etching at 20° C Although the selection of the best etchant, and its proper use, is a very critical phase of the image analysis process, only a few publications have addressed this problem. A classic example of the different behavior of etchants is given in Figure 20.2 where low-carbon sheet steel has been etched with the standard nital and picral etchants, and also a color tint etch. 1.
