In-situ production and microstructures of iron aluminide/TiC composites

Effect of alloying additions on the structure and mechanical properties of Fe3Al -1C intermetallic alloy

“…3b). This observation is in conformity with work reported by Ko and Hanada [16]. The EPMA quantitative analysis of the matrix and precipitates revealed very low concentration of Ti, (0.1% Ti) in Fe 3 Al matrix and Fe 3 AlC 0.5 precipitates suggesting that almost all Ti (75.20% Ti) was used in the formation of TiC precipitates.…”

“…Iron aluminide based on Fe 3 Al exist over a range (13)(14)(15)(16)(17)(18)(19)(20)(21) wt. % Al) of composition (all the compositions in wt.% unless otherwise specified).…”

Fabrication of TiB2 Particle Dispersed FeAl-based Composites by Self-propagating High-temperature Synthesis

“…6 may be proposed based on Ko and Hanada's hypothetical TiCFe 3 Al pseudo-binary eutectic phase diagram. 6) According to this diagram, during cooling of the liquid produced by the SHS reaction, TiB 2 crystallizes as the primary crystal, and then FeAl crystallizes by a peritectic reaction as the secondary crystal. Moreover, when TiB 2 concentration is higher, the primary TiB 2 crystal appears at higher temperatures and it coexists with the residual liquid for longer periods during cooling, which promotes the growth of TiB 2 particle at higher TiB 2 concentrations.…”

Changes in constituents and FeAl composition with oxygen content in WC–FeAl composites

“…The FeAl intermetallic alloy is used as a binding material among WC grains. This material has some advantages: good oxidation resistance at high temperature (around 800°C) [1,2] and good compatibility with carbon film [3]. The former is advantageous for cutting metals and alloys since the tip of the tool is subjected to high temperature during the cutting.…”
