Noticing that strong exothermic reaction due to large negative enthalpy of mixing can occur among major components of bulk metallic glass forming alloy systems, a new technique to fabricate an amorphous based composite material using laser induced self propagating reaction synthesis (LSRS) is developed. The LSRS for Zr Al Ni Cu alloy system shows that the products mainly consist of amorphous, Zr 3Al 2 and Zr 2Cu phases. With increasing of impure (Zr,C) in raw powder mixtures, the amount of amorphous phase in products decreases, while microhardness and wear resistance of products increase.
