Observation of Incongruent Melting in Cu10Hf7

Observation of Incongruent Melting in Cu10Hf7

Differential thermal analysis, scanning electron microscopy, and x-ray microanalysis are used to show that the intermetallic compound Cu10Hf7, previously reported as melting congruently at 1025 deg C, melts incongruently to CuHf2 and a Hf-Cu liquid at that temperature. A eutectic point previously re...

Zusammenfassung:Differential thermal analysis, scanning electron microscopy, and x-ray microanalysis are used to show that the intermetallic compound Cu10Hf7, previously reported as melting congruently at 1025 deg C, melts incongruently to CuHf2 and a Hf-Cu liquid at that temperature. A eutectic point previously reported at 43.6 at.% Hf and 980 deg C does not exist.
