We have investigated contact fusion (CF) in the Bi-Te 
binary system with a complex state diagram under different programs 
of heating the contact of specimens in the current and currentless 
regimes. CF at temperatures below the fusion temperature of the lowest 
eutectics has been revealed. It has been established that the known 
state diagram of the Bi-Te system is metastable and, depending 
on the contact heating rate, the CF processes proceed differently. 
It has been shown that the values and directions of the direct current 
passed through the contacts of Bi and Te specimens can control the 
phase-formation processes and the CF kinetics.
