摘要：

Al-rich portion of the Ir-AI phase diagram has been investigated with 10 alloys by means of differential thermal analysis, X-ray diffraction, scanning electron microscopy, inductivity Coupled plasma spectrometry and electron probe microanalysis. Invariant reactions are observed: L <-> AlIr + Al2.7Ir, L+ Al2.7Ir <-> Al3Ir, L+ Al3Ir <-> Al13Ir4, L+ Al13Ir4 <-> Al13Ir2. Although the eutectic reaction, L <-> AlIr + Al2.7Ir, cannot be regarded as definitely established by previous research, it is confirmed in the present research. Liquidus curve has been determined for the first time for Al-rich alloy (Ir <= 33.0 at%). The Ir-Al binary phase diagram has been modified based on these experimental observations.
