- Abstract
- In this work were studied density (by gamma-absorption method) and electrical resistivity (by contactless method in rotating magnetic field) of Al–Ni–Co–Ce glass-forming alloys with different ratios of transition metals. It was found the existence of a wide two-phase zone was established and jump-like changes in properties at solidus and liquidus temperatures. Increasing of cobalt content from 2 to 4 at % leads to 2% decrease of density and 3% increase of electrical resistivity in crystalline and liquid states. Temperature coefficients of change in properties were calculated. Density hysteresis was detected, which occurs when melts are overheated above 1350 K. This fact is related to the disintegration of large-scale microheterogeneities that exist in melts during heating. It is shown that these results can be used to optimize the process of obtaining rapidly hardened alloys.
