摘要

Phase transition in the crystalline and amorphous Ti/sub y/CuH/sub x/ system, where y = 1 or 2 and 0 less than or equal to x less than or equal to 2.71, were investigated using differential scanning calorimetry (DSC) at temperatures between 330K and 990K. Room temperature x-ray diffraction (XRD) measurements were made to identify the phases and unit cell parameters before and after the DSC runs. The transition temperatures, kinetic activation energies, and heats of transition were found to be dependent upon the hydrogen concentration. While the trends in transition temperature and kinetic activation energy agree with one another, the heat of transition does not follow the same trends. (ERA citation 10:007141)
