چکیده انگلیسی
Effects of the single or simultaneous addition of trace Ti and B (⩽1 at.%) on the glass-forming ability (GFA) and crystallization behaviors of Al88Ni6La6 and Al89Ni6La5 amorphous alloys were investigated by X-ray diffraction and differential scanning calorimetry. The addition of trace Ti and B deteriorates the GFA, but improves the thermal stability especially if Ti is added singly. The crystallization onset temperature Tx1 of the first exothermic peak increases by 29.5 and 18.0 K when 1% of the Al atoms in Al88Ni6La6 and Al89Ni6La5 are replaced by Ti, respectively. However, the primary phase during annealing remains unchanged.
