Notes:
Research results focussed on the combined influence of iron and boron, in proportions of0.5 and up to 10 wt.% respectively, in complex alloyed Ni3Al synthesised by Self Propagating HighTemperature Synthesis (SHS) in the thermo-explosion mode at two ignition temperatures, 950 and1150 oC, are presented. By XRD and Mössbauer spectroscopy it was established that for 950 oCignition temperature, the evolved heat is not high enough for the added Fe to be fully incorporatedinto the synthesised Ni3Al phase, a temperature of 1150 oC being required. For this temperature, thedensity of the synthesised alloys, their capacity to be cold deformed by re-pressing, hardness andbending strength variations as a function of B and Fe contents, proved their cumulative effects ofthe ductility and mechanical properties of complex alloyed Ni3Al enhancing
