- •
Chemical interactions between dissimilar atoms exist always, in all alloys and at any temperature.
- •
Many alloys have the ability to change the sign of the chemical interaction energy with temperature.
- •
Change of the sign of the chemical interaction energy changes the type of microstructure.
- •
Ordering-phase separation’ transitions in the Co2V alloy occur at 800 and 450 °C.
- •
Methods of determining temperature of the transition ‘ordering-phase separation’ are proposed.
