Bulk Fe-Al-C Nanoalloys Made by Mechanically Alloying with Subsequent Spark Plasma Sintering and Their Mechanical Properties

The mechanisms of microstructure formation in a nanostructured oxide dispersion strengthened FeAl alloy obtained by spark plasma sintering

“…Thus, the SPS technique has a high potential to produce bulk nanostructured materials from the original nanostructure present in the milled powder. For example, it has been reported that dense nanostructured Fe 3 AleC [19] and (Al þ 12.5 at.% Cu) 3 Zr [20] intermetallics sintered by SPS processing of milled powder showed excellent mechanical properties. Little is known, however, on the nature of the mechanisms involved in the formation of the microstructure associated with the SPS processing.…”

Synthesis and characterization of Fe3AlC0.5 by mechanical alloying

“…Y. Minamino et al [3] have carried out an investigation of the microstructure and mechanical properties of bulk nanocrystalline Fe Al C alloys made by mechanical alloying with subsequent spark plasma sintering. They have reported that the castings with fine precipitates of Fe 3 AlC 0.5 exhibit superior mechanical properties (strength, rupture strain and Vickers hardness) than those of ordinary Fe 3 Al.…”

“…These double carbides have their distinctive crystal structures and properties. One of the most interesting types is that of the cubic perovskite structure such as: Fe 3 AlC 0.5 , which has been reported previously [2,3,4].…”

Synthesis and characterization of Fe6W6C by mechanical alloying

“…It is well known that by means of the mechanical alloying technique, it is possible to extend the Solid solubility limits; besides the graphite acts as well as a lubricant and a process control agent [4]. This fact allows forming a true alloy in a short time.…”
