An investigation on formation of Nb2AlC by combustion synthesis of Nb2O5–Al–Al4C3 powder compacts

Effects of Al and Al4C3 contents on combustion synthesis of Cr2AlC from Cr2O3–Al–Al4C3 powder compacts

“…The SHS technique has been applied to produce a number of the MAX carbides, like Ti 3 SiC 2 [27], Ti 3 AlC 2 [28], Ti 2 AlC [29], Ta 2 AlC [30], Nb 2 AlC [31], and Ti 2 SnC [32]. However, the formation of Cr 2 AlC from its constituent elements by the SHS process is unfeasible, due mostly to insufficient exothermicity of the reactions among Cr, Al, and carbon [33].…”

Effects of TiC addition on formation of Ti2SnC by self-propagating combustion of Ti–Sn–C–TiC powder compacts

“…When compared with the above-mentioned methods, combustion synthesis in the mode of self-propagating high-temperature synthesis (SHS) takes advantage of the self-sustaining merit from highly exothermic reactions and hence has the benefits of low energy requirement, short reaction time, and simple facilities [14][15][16]. Moreover, the SHS technique has been effectively applied to produce a number of the MAX carbides, like Ti 3 SiC 2 [17,18], Ti 3 AlC 2 [19,20], Ti 2 AlC [21,22], Ta 2 AlC [23], and Nb 2 AlC [24]. As the first attempt, this study aims at the synthesis of Ti 2 SnC by solid state combustion in the mode of SHS with the green samples compressed from both the Ti-Sn-C and Ti-Sn-C-TiC powder mixtures.…”

Formation of Ti2AlC0.5N0.5 solid solutions by combustion synthesis of Al4C3-containing samples in nitrogen

“…Extensive studies were performed on many MAX compounds, such as Ti 3 SiC 2 , Ti 3 AlC 2 , Ti 2 AlC, Cr 2 AlC, and Ti 2 AlN [4][5][6][7][8][9][10]. Fabrication of the MAX phases has been conducted through a variety of processing routes; for example, hot pressing (HP) [2,4,5], hot isostatic pressing (HIP) [6,7], in situ hot pressing/solid-liquid reaction synthesis [10][11][12][13][14][15], pulse discharge sintering (PDS) [16][17][18][19], and self-propagating hightemperature synthesis (SHS) [20][21][22][23][24][25].…”

“…The SHS technique has been effectively utilized to produce a number of the MAX carbides, like Ti 3 SiC 2 [20], Ti 3 AlC 2 [21], Ti 2 AlC [22], Ta 2 AlC [23], Nb 2 AlC [24], and Ti 2 SnC [25]. Recently, Yeh et al [40] first prepared Ti 2 AlC 0.5 N 0.5 from TiC-and TiN-diluted Ti-Al-C powder compacts by combustion synthesis in either solid-gas or solid state mode.…”
