Work hardening in Fe–Al alloys

Low cycle fatigue of Fe3Al-based iron aluminide with and without Cr

“…This is consistent with results of Morris et al [9], who observed "a good degree of D0 3 order for Fe 3 Al alloys containing 25e30 at% Al" that were drop-cast into 25 mm diameter copper molds. Fig.…”

Precipitation in ductile Fe–18Al–5Cr alloys with additions of Mo, W and C and effects on high-temperature strength

“…After room temperature deformation, Fig. 6a, dislocations were arranged in planar arrays, as is typical for alloys containing short-range order [43]. These dislocations appear to be mostly near-screw dislocations of Burgers vector 1/2C111D type.…”

Dependence of the yield stress of Fe3Al on heat treatment

“…Herrmann et al [6,7] studied the yield stress behavior of annealed and quenched alloys from nearly pure iron up to 18at%Al. Morris et al [14] complemented these data with those for alloys containing 20e40at%Al. They found an initial linear increase of yield stress with increasing Al concentration due to solid-solution hardening and short range order hardening.…”
