An investigation on the microstructure and peritectic reaction involving icosahedra phase(l-phase) and crys- talline phase(W-phase)within Mg-Zn-Y alloy during conventional solidification technology and rapid quench- ing was carried out.The solidification process of the peritectic reaction is discussed in details.It is shown that there is no obvious crystallographic relationship between the W-phase and l-phase during the solidification of Mg-Zn-Y alloy.
