Abstract

Two-phase β-NiAl/γ'-Ni₃Al base intermetallics were produced by combustion synthesis from elemental powder mixtures. Compositions belong to the system Ni-Al-Fe-Cr-B-Ti-(Hf or Ta). The combustion synthesis of binary -βNiAl intermetallic was also studied. The mixes were uniaxially pressed (200 and 600 MPa) without internal lubrication. The ignition temperature was determined by differential scanning calorimetry (DSC) in argon using a heating rate of 10°C/min. Hot consolidation was carried out by pressureless sintering in argon, hot pressing (HP) at 35-50 MPa in argon or vacuum, and hot isostatic pressing (HIP) at 200 MPa, at different temperatures and times. Density, Vickers hardness, and the content of oxygen, nitrogen, carbon, and sulphur were measured at every stage of processing. The main constituents were identified by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The mechanical properties of multicomponent intermetallics were evaluated by tensile tests at room temperature and 1000°C.
