Did you know?
A peritectoid reaction
is an isothermal reversible reaction in which two solid phases decompose
into a third solid phase upon cooling. An example of a peritectoid transformation is provided by the formation
of the intermetallic compound U3
Si in uranium-silicon alloys (see figure). Casting uranium
at the proper concentration of silicon (3.78 wt%, or 24.98 at.%) results in a mixture of the uranium terminal
solid solution and U3
