“…Chua et al has reported that, for Mg-SiC composite, use of smaller particles of SiC results in relatively higher elastic modulus and tensile strength in a large number of thermal shock cycles [9]. It has also been reported by Rahimian et al [8] that, for Al-Al 2 O 3 composites, increase in the sintering time at 600 ∘ C from 60 to 90 min leads to reduction in hardness from 67 to 59 HB.…”

“…Therefore, it can be concluded that the particle size of the powder taken from electron micrographs is in close proximity with that of the manufacturer's specification. Figures 7,8,and 9 show the SEM of specimens 10AFe900(1), 10AFe900(2), and 10AFe1100 (1) at (a) 5000x and (b) 20000x magnification, respectively. The microstructures are provided in such a sequence in order to study the effect of composition, sintering temperature, and the sintering time, respectively.…”

The present paper reports the investigations on sintering and hardness behavior of Fe-Al 2 O 3 Metal Matrix Nanocomposites (MMNCs) prepared by Powder Metallurgy (P/M) route with varying concentration of Al 2 O 3 (5-30 wt%). The MMNC specimens for the present investigations were synthesized by ball milling, followed by compaction and sintering in an inert atmosphere in the temperature range of 900-1100 ∘ C for 1-3 hours using Powder Metallurgy route. Phase and microstructures of the specimens were characterized by XRD and SEM. Reactive sintering takes place in these materials. During sintering nano iron aluminate (FeAl 2 O 4 ) phase forms. Characterization was done by measuring density and hardness. Results have been discussed critically to illustrate the effect of various processing parameters on sintering and mechanical behavior. It is expected that the results of these investigations will be useful in developing Metal Matrix Nanocomposites (MMNCs) for typical industrial applications.

These were sintered at 400 ∘ C for 30 min followed by extrusion. SEM micrographs of as extruded polished composites reinforced with different sizes of SiC in the transverse direction revealed that although some agglomeration of SiC particles could be observed, the overall distribution generally appeared to be reasonably homogeneous.…”

The present paper reports phase, microstructure, and compressive strength of ZrO 2 reinforced Fe Metal Matrix Nanocomposites (MMNCs) synthesized by powder metallurgy (P/M) technique. High purity grade iron metal powder was mixed with varying percentage of zirconium dioxide (5-30 wt%), compacted, and sintered in argon atmosphere in the temperature range of 900-1100 ∘ C for 1 to 3 hours. X-ray diffraction (XRD) analysis of specimens was done in order to study the phases present and scanning electron microscopy was carried out to determine the morphology and grain size of the various constituents. XRD result shows the presence of Fe, ZrO 2 , and Zr 6 Fe 3 O phase. Zr 6 Fe 3 O phase forms due to reactive sintering and is not reported earlier by researchers throughout the globe. SEM results showed the presence of dense microstructure with the presence of Fe, ZrO 2 , and some nanosize Zr 6 Fe 3 O phases.

Mechanical Properties Enhancement of Particle Reinforced Magnesium Matrix Composites Used for Hot Extruded Tubes

et al. 2015

View full text Add to dashboard Cite

This paper studies new magnesium metal matrix composites (Mg MMCs) reinforced with SiC particles by the stir-casting method for MMCs tubes hot extrusion. AZ61/SiCp MMCs' ingots reinforced with 0, 0.5 and 1 wt.% SiC particles are fabricated by the melt-stirring technique. AZ61/SiCp MMCs' tubes are manufactured by hot extrusion using a specially designed die-set. Obvious grain size renement both by addition of particles and extrusion process are discovered. However, the grain renement eect caused by extrusion process is much signicant than that eect caused by SiC particle addition. The 0.2% yield strength (YS) of extruded tubes of AZ61 and AZ61/1 wt.% SiCp MMCs (without and with T5 treatment) are increased by 140.9161.9% and 156.5 156.7%, respectively, compared with those of as-cast billets.
