The effect of heat treatment on the structure of Nb and Cr doped Fe Al alloy
Original language description
The alloyed iron aluminides with Fe3Al matrix are used as structural materials. Nb, Cr, Zr, Ti, Ta, Mo additives appear like promising for high-temperature applications [1]. The Nb addition leads to the formation of niobium carbides in the structure of the alloy [2]. Presence of this phase in an appropriate shape could enhance high-temperature mechanical properties of aluminides. The effect of the Nb addition on the phase composition of this alloy was studied [3,4]. The effect of the heat treatment on the structure was also observed. The alloy was annealed at 1150°C/2h and 1400°C/100h in the air for the confirmation of the phase stability. The phase composition was studied by light optical microscopy (LOM) and scanning electron microscopy (SEM) with energy dispersive analysis (EDX). Also Vickers hardness was measured for all states. High ? temperature mechanical properties are tested as Rp0,2 in tension.
