Thermophysical properties of U2Mo intermetallic

The current paper has investigated specific heat capacity, coefficient of thermal expansion and phase transition temperatures of U2Mo intermetallic. The transformation of U2Mo phase to bcc ( gamma -uranium) phase occurred at 853 K. The coefficient of thermal expansion has been determined in the temp...

Description
Summary:The current paper has investigated specific heat capacity, coefficient of thermal expansion and phase transition temperatures of U2Mo intermetallic. The transformation of U2Mo phase to bcc ( gamma -uranium) phase occurred at 853 K. The coefficient of thermal expansion has been determined in the temperature range 423-873 K to be 14.65 10-6 K-1. The specific heat data showed a smooth curve up to 773 K and above it a change in trend to follow a lambda -shape was observed. The specific heat values of U2Mo have been found to be lower than that calculated from the additivity rule. This study provides first time data on U2Mo. The data obtained from this investigation were compared to available literature on U-Mo alloys.
