4. INTERMETALLIC
◈It is a phase formed by the intermediate composition
between the two primary components(pure metals)
◈The crystal structure of the intermediate phase is
different for both the primary component
◈ these intermediate phase have a fixed composition
they are called intermetallic compound

5. intermetallic compound of aluminum alloys
◈In the case of aluminum alloy aluminum phase is
intermediate with other phase
◈ if examples are REAuAl2Si
REAu2Al4Si
EuAu3Al6Si
REAu4Al8Si
REAu5Al10Si
