Cg. De Andres et al., Metallographic techniques for the determination of the austenite grain size in medium-carbon microalloyed steels, MATER CHAR, 46(5), 2001, pp. 389-398
Different techniques have been investigated to seek the best procedure to r
eveal the prior-austenite grain boundaries in three medium-carbon microallo
yed steels. This study has been carried out over a wide range of temperatur
es (950-1250 degreesC) and it has been found that thermal etching (TE) is t
he best technique to reveal the prior-austenite grain boundaries in these s
teels. (C) 2001 Elsevier Science Inc. All rights reserved.
