AN AUTOGRAPHIC STRAIN-GAGE DILATOMETER FOR PLUTONIUM AND ITS ALLOYS
A vacuum dilatometer for use in determiming the expansion characteristics of plutonium and its alloys is described. The dilatometer consists of a vertical silica tube containing the specimen and a silica push tube which transmits specimen expansion to a cantilever beam. Strain gages cemented to the beam convert linear displacement of the specimen into an electrical signal that is fed to a Leeds and Northrup X-Y recorder. Specimen temperature, as determined by a thermocouple, is also fed to the recorder. Heating of the specimen is obtained by means of at split-tube furnace. The principal advantages of this dilatometer over the popular silica-tube and dialindicator dilatometer include light loading of the specimen and continuous autographic recording of expansion-versustemperature data. Experience hns shown this dilatometer to be simple in operation, reliable and adaptable to determining the expansion characteristics of a large number of plutonium alloys. (auth)
