Test for Transformation15.1 Cut the specimen from any part of the material, butpreferably includ
36、ing the entire cross section, degrease it, thenheat treat it as described in 13.1. When cool, polish the crosssection of the specimen and etch (Note 5) it in accordance withMethods E3. Then subject the specimen to the temperatureproduced by an excess of dry ice in methanol (78.5C) for atleast 4 h. A
37、fter the low-temperature treatment, examine thespecimen at a magnification of 1503 for the presence of theacicular crystals characteristic of the alpha phase. Becausethese crystals may occur only in small localized areas, examinecarefully the entire polished cross section.NOTE 5A suggested etchant i
38、s a solution of three parts by volume ofconcentrated hydrochloric acid and one part of concentrated nitric acidsaturated with cupric chloride (CuCl22H2O). This etchant is moreeffective when allowed to stand for 20 min after mixing. After severalhours it loses its strength and should be discarded at
39、the end of the day.Etching is best accomplished by swabbing the specimen with cottonsoaked with the etchant. Etching is usually complete when the surface ofthe metal appears to have turned dull.15.2 Specimens that show no transformation and that showpartial transformation are illustrated in Fig. 1 a
