Cool the specimen from 1100 to200C in the hydrogen atmosphere at a rate not to exceed5C/min.12.2 Determine the thermal expansion characteristics inaccordance with

23、 Test Method E228.NOTE 2For critical glass sealing applications, it is recommended thatthe user conduct functional testing in accordance with Practices F14, F140or F144. Such tests circumvent possible problems with thermal expansionmeasurements and glass setting point estimates.NOTE 3The thermal tre

The 196Ctransformation temperature corresponds to immersing a sample (preparedaccording to 14.1) in liquid nitrogen for a minimum of 1 h.14. Test for Transformation14.1 Cut the s

31、pecimen from any part of the material, butpreferably including the entire cross section, degrease it, thenheat treat it as described in 12.1. When cool, polish the crosssection of the specimen and etch (Note 5) it in accordance withMethod E3. Then subject the specimen to the temperatureproduced by a

32、n excess of dry ice in acetone (78.5C) for atleast 4 h. After the low-temperature treatment, examine thespecimen at a mangification of 150 for the presence of theacicular crystals characteristic of the alpha phase. Becausethese crystals may occur only in small localized areas, examinecarefully the e

34、rated 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 the end of the day.Etching is best accomplished by swabbing the specimen with cottonsoaked with the etchant. Etchin
