摘要
The heat resistance of Ni-Al alloys with 4d- or 5d-transition element additives (zirconium, hafnium, niobium, tantalum or tungsten) has been studied at high temperatures: 1373, 1473 and 1573 K. Some regularities for the efect of 3d-, 4d- and 5d-transition element additives on Ni-Al oxidation have been found. The oxidation kinetics are described by linear and square laws. The boundary concentrations of additives stabilizing the resistance to oxidation of Ni-Al alloys have been found. The relation between alloy sub-structures and change in heat resistance is discussed.
