“…Chelluri performed compaction of a tungsten steel composite; after preheating the powder at 1,000°C and subjecting the compaction to multiple compaction cycles, compaction close to 99 % of the theoretical density of the alloy was produced [27]. Popov et al produced MMC with aluminum base and silicon carbide reinforcement through dynamic consolidation of mechanically alloyed composite powders [28]. They managed to produce sound composite materials with a homogenous distribution of reinforcement particles and the hardness of the materials seems to increase with an increase in the milling time.…”

The innovation of advanced materials and their application to engineering structures can be related to their ease of fabricating defect-free parts. The identification of various energy sources has resulted in various new processing techniques in manufacturing and electromagnetic energy is one which offers promising qualities for high-velocity forming, welding, and compaction of metals. Bimetallic joint designs were proposed in automobiles to reduce the weight and to take advantage of properties of different metals in the same construction. Joining by fusion is impossible in certain cases due to huge differences in melting point, thermal conductivity, volumetric specific heat, and coefficient of thermal expansion. In the present study, magnetic-pulse welding of a Cu/Al joint and an ODS alloy is investigated. The formation of intermetallic phases and interface morphology is presented along with a quantitative analysis for temperature in the Al/Cu joint. Also, initial investigations on the application of electromagnetic energy for compaction of aluminum powders are reported.

“…In order to meet industry demands, a number of researchers have investigated mechanically alloyed (MA) Al based materials reinforced with non-soluble ceramic particles such as SiC or Al 2 O 3 fine dispersions. [1][2][3][4][5][6][7][8] Additional composite strength increase can be obtained by precipitation hardening of the alloyed Al matrix. [5][6][7][8][9][10][11] Superposition of strain hardening, grain refining, and precipitation hardening processes is one of the most effective methods for strengthening metallic materials in practice.…”

A mechanical alloying and hot extrusion method was used to manufacture an Al based composite reinforced by 10 wt-% addition of Nb 2 O 5 . Annealing experiments were performed to test the effect of chemical reaction between components on the material structure. After annealing at 873 K for 12 h the material hardness was found to have increased from HB 121 (as extruded) to HB 186 (annealed). The hardness maximum was followed by material softening at prolonged aging at 873 K. Transmission electron microscopy observations revealed a very well consolidated nanoscale structure for the as extruded composite. Annealing of the material resulted in an increase in porosity that was ascribed to Nb oxide reduction by aluminium. Due to diffusion of the released Nb element into the surrounding Al matrix, formation of new intermetallic grains of Al 3 Nb was accompanied by very fine needlelike Al oxide particle growth within the aluminium matrix. Chemical reaction between aluminium and Nb oxide at solid state was related to local specific volume reduction being responsible for an increase in the material porosity. Hot compression tests were performed on as extruded and samples annealed at 873 K for 12 h. The good mechanical properties of the composite were ascribed to the highly refined structure of the material. In compression tests, samples were not fractured within the experimental strain range used. In hot deformation tests at lower temperatures and a strain rate of 5 10 23 s 21 , some fine microcavities were observed by TEM for samples deformed to e t <0?3.
