“…Nawathe et al [41] also reported that the average microhardness, compressive yield strength, as well as compression strength were enhanced with an increase of both (Ti,W)C reinforcement level and sintering temperature, as shown in Figure 17. An interesting point noticed here was that a small amount of the liquid Al phase appeared around the (Ti,W)C due to the better absorbing ability of (Ti,W)C to microwave and heat concretion due to the angular initial powder.…”

“…At the same time, the porosity The fabrication and characterization of 6061 Al alloy reinforced with different content of reinforcements (i.e., 10, 20 and 30 wt. % (Ti,W)C) were studied by Zheng and his co-workers [41]. The 6061 Al alloy powder and (Ti,W)C powder were prepared by mechanical alloying using a two-station planetary ball mill for 1 h with a ball-to-powder ratio of 5:1 and a milling speed of 200 rpm.…”

“…The strength of Ni60Nb40 amorphous particle-reinforced aluminum composites increased with increasing the volume fraction of reinforcements. Furthermore, they compared the mechanical properties (ultimate tensile strength and ductility) of their composite with those of traditional ceramic-reinforced MMCs [40,41], as shown in Figure 13. Engineering stress-strain curve of pure Al and Al-Ni60Nb40 amorphous particle reinforced composites under: (a) compression and (b) tensile loading conditions.…”

Aluminum metal matrix composites (AMMCs) are light-weight materials having wide-spread use in the automobile and aerospace industries due to their attractive physical and mechanical properties. The promising mechanical properties of AMMCs are ascribed to the size and distribution of the reinforcement, as well as to the grain size of the matrix. Microwave rapid sintering involves internal heating of aluminum compacts by passing microwave energy through them. The main features of the microwave sintering technique are a short processing time and a low energy consumption. The aim of this review article is to briefly present the microwave rapid sintering process and to summarize the recent published work on the sintering and properties of pure Al and Al-based matrix composites containing different reinforcements.

“…Compared with traditional methods, powder metallurgy (P/M) process has numerous advantages for fabricating small pieces of complicated shapes, because it allows material and energy savings as well as dimensional accuracy [15][16] . Moreover, it has better control on the microstructure where better distribution of the reinforcements is possible, and this great influence on the end properties [17][18][19] . In recent years, extensive work has been undertaken to sinter metal matrix composites which contain ceramic particles embedded in the metal matrix.…”

Effect of High Energy Milling Time of the Aluminum Bronze Alloy Obtained by Powder Metallurgy with Niobium Carbide Addition

et al. 2017

The aluminum bronze alloy is part of a class of highly reliable materials due to high mechanical strength and corrosion resistence being used in the aerospace and shipbuilding industry. It's machined to produce parts and after its use cycle, it's discarded, but third process is considered expensive and besides not being correct for environment reasons. Thus, reusing this material through the powder metallurgy (PM) route is considered advantageous. The aluminum bronze chips were submitted to high energy ball milling process with 3% of niobium carbide (NbC) addition. The NbC is a metal-ceramic composite with a ductile-brittle behaviour. It was analyzed the morphology of powders by scanning electron microscopy as well as particle size it was determined. X ray diffraction identified the phases and the influence of milling time in the diffractogram patterns. Results indicates that milling time and NbC addition improves the milling efficiency significantly and being possible to obtain nanoparticles.
