Laser-Induced Self-Propagating Reaction Synthesis of Zr-Ti-Ni Quasicrystal
Noticing that strong exothermic reaction due to large negative enthalpy of mixing can occur among major components of the Zr-Ti-Ni quasicrystalline alloy systems, a new technique to fabricate quasicrystalline material using laser-induced self-propagating reaction synthesis (LSRS) is developed The LSRS for Zr-Ti-Ni alloy system shows that the product is mainly composed of the quasicrystalline I - phase, the α (Ti/Zr) solid-solution and the Laves phase with MgZn2 structure type. However, the content of the I-phase in the products changes with the composition of the raw powder mixtures. When the composition of the raw powder mixtures changes from Zr44Ti40Ni16 to Τi40Ζr40Νi20 and the content of the I-phase decreases. The microhardness of the samples increases with the increase of the content of the I-phase.
