Based on a large negative enthalpy of mixing among major components of bulk metallic glass forming alloy systems, a new technique to fabricate amorphous based composite materials using laser induced selfpropagating reaction synthesis (LSRS) was developed. The LSRS of the Zr55Al10Ni5Cu30 alloy shows that the products mainly consist of the amorphous, Zr3Al2 and Zr2Cu phases. However, the amorphous phase content in the products is closely related to laser power and ignition time: high laser powers and short ignition times increase the content of the amorphous phase. The microhardness of the samples decreases with the increase of the content of the amorphous phase.
