Pulsed Heating of Carbides

详细

Experimental studies of carbides are briefly reviewed. The high-temperature properties of carbides used in nuclear power and aerospace engineering are considered. Temperature is measured from either plane surface emittance or the emittance of thin samples prepared in the form of a melting blackbody model. The following quantities are measured: Joule energy, heat capacity (predominantly С_p), electrical resistance, and phase-transition heat versus temperature (up to 5000 K). The pre-melting heat capacity exceeds the equilibrium value, but temperatures measured at the characteristic points of the phase diagram correspond to the design diagram.
