- W890666565 abstract "The Mg-5Zn-1Y-0.6Zr alloys were prepared by conventionally solidified method and rapidly solidified method. The solidification microstructures and properties of the alloys were observed by XRD, SEM and micro-hardness measurements. The results indicate that the conventionally solidified alloy is composed of preliminary α-Mg matrix and interdendritic ternary phases of I-(Mg3Zn6Y) quasi-crystal phase and W-(Mg3Zn3Y2) phase in the grain boundary. The rapidly solidified alloys are composed of fine α-Mg matrix phase, amorphous phase and quasicrystal I-phase. The amorphous phase and ultra-fine phase are the main reason to increase the micro hardness value of the alloy ribbon. With the increase of cooling rate, the micro-hardness of the rapidly solidified alloys increase tremendously. The maximum micro-hardness value of the rapidly solidified alloy is HV167.23, which is 2.2 times the size of the conventionally solidified alloy." @default.
