Gugh Sped Steel Acid Etching at ganttefecarablog Blog


Gugh Sped Steel Acid Etching. The etching of prior austenite grain boundaries in martensite for detailed quantitative metallography of low to high carbon steel has been carried out using aqueous. To evaluate these etchants, eight specimens (seven different compositions) with m3c, m23c6, m7c3, m6c, m2c and mc carbides.

The examples show that fully martensitic, quenched and tempered alloy steels from ~0.2 to 0.8% carbon can be successfully etched using hot saturated aqueous picric acid plus a small amount of hcl and a wetting agent. The etching of prior austenite grain boundaries in martensite for detailed quantitative metallography of low to high carbon steel has. Examination of selectively etched tool steel microstructures by light microscopy provides more information than standard.
