“…It is interesting to mention here that even though the hardness of nanocomposites of Al-Fe alloys drops after annealing at 773 K, the hardness is still higher than that of hardness of cold compacts of Al-Fe alloys (Fig. 10b) and that of nanocomposites reported earlier in Al-based alloys including Al-Fe alloys [1,28,[33][34][35][36][37]. The reduction in hardness values of the Al-Fe alloys after annealing at high temperature of 773 K can also be attributed to the coarsening of the microstructure (Fig.…”

“…The point to be noted is that there is very little solid solution between these two metals. Hence, Al-Fe alloys can be produced only in solid state by mechanical alloying (MA), 11,[13][14][15][16] severe plastic deformation by torsion, 17) and rapid solidification processing (RSP). 12) Microstructure of an Al-Fe alloy depends greatly on the atomic percent of Fe, and the processing method.…”

“…Taking σ y = H V /3, a rough estimate of the yield strength of Al-4 mass%Fe alloy produced after 400 BMA cycles is 340 MPa. 11) Since the yield of stress of pure aluminum is about 35 MPa, this strengthening is attributed not only to grain size refinement but also to precipitation hardening by the above Fe-Al intermetallic compounds.…”

Solid State Recycling of Recyclable Aluminum Wastes with In-Process Microstructure Control

Aiming for actual dematerialization, mass flow must be optimized to make full use of the recyclable materials as input and to reduce total amount of wastes. Since the material efficiency is strongly dependent on their adaptivity to the design demand for recycled products, an effective recycling process must accompany the advanced materials processing and manufacturing to improve their original properties to the level above the demand. In the present paper, the light-mass non-ferrous metallic alloys such as aluminum alloys are targeted, to utilize their bulk wastes, which are often ejected from the electric parts or members, as an input material, and to aim for their reuse as an automotive part. Dense, high-strengthened aluminum alloy compact, or, green materials are handled in the present forming and manufacturing up to the final net-shape formation of products by sinter-forging. Selection of reused materials and in-process improvement of their properties are essential keys in this barrier-free processing. Possibility to replace the conventional processing with this barrier-free process lies in: (1) Reduction of in-process energy and mass consumption, (2) Flexibility to yield various kinds of products without any realignment of processes, and (3) Adaptive in-process material modification to design for products in practical use.

“…The strengthening effect can be enhanced by increasing the solid solubility of Fe in the Al matrix by some nonequilibrium processing techniques, viz. rapid solidification processing (RSP) (Tonejc and Bonefasčić 1969;Young and Cline 1981;Riontino and Zanada 1994;Badan et al 1996), mechanical alloying (MA) (Huang et al 1990;Niu et al 1994;Mukhopadhyay et al 1995;Fadeeva and Leonov 1996;Kaloshkin et al 2002) and severe plastic deformation (SPD) (Senkov et al 1998). These non-equilibrium processing techniques can refine the microstructure of metals and alloys up to nanometer-level, and lead to the formation of metastable phases including supersaturated solid solutions.…”

Structure of nanocomposites of Al-Fe alloys prepared by mechanical alloying and rapid solidification processing

Structures of Al-based nanocomposites of Al-Fe alloys prepared by mechanical alloying (MA) and subsequent annealing are compared with those obtained by rapid solidification processing (RSP). MA produced only supersaturated solid solution of Fe in Al up to 10 at.% Fe, while for higher Fe content up to 20 at.% the nonequilibrium intermetallic Al 5 Fe 2 appeared. Subsequent annealing at 673 K resulted in more Al 5 Fe 2 formation with very little coarsening. The equilibrium intermetallics, Al 3 Fe (Al 13 Fe 4 ), was not observed even at this temperature. In contrast, ribbons of similar composition produced by RSP formed fine cellular or dendritic structure with nanosized dispersoids of possibly a nano-quasicrystalline phase and amorphous phase along with α-Al depending on the Fe content in the alloys. This difference in the product structure can be attributed to the difference in alloying mechanisms in MA and RSP.
