“…Various powder metallurgy (P/M) methods can be used to produce these materials, with advantages over casting techniques. Fully dense FeAl products have already been successfully fabricated by both extrusion [712] and cold rolling [13,14] of alloy powders. The room temperature mechanical properties of these alloys, particularly the combination of ductility and strength, are known to be sensitive to the processing-induced microstructure [15].…”

“…[13] With the exception of the aggressive studies by the Oak Ridge groups, there have been few recent publications with regard to the application of this material. [14][15][16][17] From the viewpoint of material processing for structural applications, the fabrication of iron aluminide intermetallics to arbitrary shapes, such as that of a sheet or rod, using conventional equipment, might be rather difficult.…”

Laminates of an iron-aluminum alloy (20Al) and three types of steel-chromium molybdenum (CrMo), high carbon (FeCMn), and precipitation hardening steel with niobium carbide (FeCNb)-were fabricated at 600°C and 1000°C by clad rolling based on the compression stress ratio of 20Al to steel. The laminates fabricated at 600°C exhibit a deformation microstructure with partial recrystallization, while those at 1000°C reveal a refined microstructure. The 20Al layer of all the laminates exhibit a {001}AE110ae texture, and the intensity of the texture increases with a decrease in the fabrication temperature and an increase in the reduction. The bending deformability of a laminate increases with a decrease in the compression stress ratio and by a reduction in the intensity of the {001}AE110ae texture. The clad plate is further rolled at room temperature to a thickness of approximately 150 mm, which enables winding without damage. It is concluded that a high-strength steel at high temperatures and a high Al content in the Fe-Al alloy is beneficial for the fabrication of deformable laminates.

“…14 Efforts to improve ductility of Fe-base intermetallics at room temperature have been addressed by appropriate processing, microalloying, and oxide dispersion strengthening (ODS), [15][16][17][18][19][20] which has led to grain boundary strengthening and grain size reduction. Since a small grain size is indispensable to get a reasonable ductility at room temperature of this type of intermetallics, 21 a fine dispersion of yttria particles was introduced by mechanical alloying with pre-alloyed powders.…”

Potential of FeAlCr intermetallics reinforced with nanoparticles as new biomaterials for medical devices

Novel FeAlCr oxide dispersion strengthened intermetallics that are processed by powder metallurgy have been developed as potential biomaterials. The alloys exhibit a small grain size and a fine dispersion of yttria provides the material with a high yield strength and depending on the alloy composition good ductility (up to 5%). The biocompatibility of the alloy was assessed in comparison with commercial alumina. Saos-2 osteoblast-like cells were either challenged with mechanically alloyed particles, or seeded onto solid samples. Viability and proliferation of cells were substantially unaffected by the presence of a high concentration of particles (1 mg/mL). Solid samples of novel FeAlCr intermetallic have shown a good biocompatibility in vitro, often approaching the behavior of materials well known for their biological acceptance (e.g. alumina). It has been found that osteoblasts are able to produce ALP, a specific marker of cells with bone-forming activity. In this respect, ALUSI alloys hold the promise to be suitable substrate for bone integration. The finding of no cytotoxic effect in the presence of the alloy particles is a reliable proof of the absence of acute toxicity of the material.
