Intermetallic particles form during solidification of metallic alloys.

Aluminium alloys

For example Al-Si-Cu-Mg alloys form Al5FeSi- plate like intermetallic phase, Chinese scipt like -Al8Fe2Si, Al2Cu, etc. The size and morphology of these intermetallic phases in these alloys control the mechanical properties of these alloys especially strength and ductility.[1] The size of these phases depends on the secondary dendrite arm spacing[2], as well as the Si content of the alloy[3][4][5][6][7], of the primary phase in the micro structure.

Magnesium alloys

In-situ synchrotron diffraction experiment[10] on Electron alloy-WE 43 (Mg4Y3Nd) shows that this alloy form the following intermetallic phases ;Mg12Nd, Mg14Y4Nd,and Mg24Y5.
