Investigation of metal and ceramic-matrix composites moduli: Experiment and theory

Sintering and Hardness Behavior of Fe-Al2O3 Metal Matrix Nanocomposites Prepared by Powder Metallurgy

“…The iron aluminate phase is formed due to the reactive sintering between the iron and alumina particles. More amount of Al 2 O 3 and less amount of FeAl 2 O 4 phase were found in the specimen 10AFe900(2) whereas a large amount of FeAl 2 O 4 and small amount of Al 2 O 3 phase was found in the specimen 10AFe1100 (2). It can be concluded from the above discussion that as the sintering temperature increases the iron aluminate phase formation also increases.…”

“…Figure 2 shows XRD pattern of specimens (a) 10AFe900 (2), (b) 10AFe1000 (2), and (c) 10AFe1100 (2). Specimen 10AFe900 (2) shows the formation of Fe, Al 2 O 3 , and FeAl 2 O 4 phases, respectively.…”

“…Figure 2 shows XRD pattern of specimens (a) 10AFe900 (2), (b) 10AFe1000 (2), and (c) 10AFe1100 (2). Specimen 10AFe900 (2) shows the formation of Fe, Al 2 O 3 , and FeAl 2 O 4 phases, respectively. Similar to specimen 10AFe900(2) the other two specimens, that is, 10AFe1000(2) and 10AFe1100 (2), also showed the presence of Fe, Al 2 O 3 , and FeAl 2 O 4 phases.…”

“…There are several routes which are put forth by researchers throughout the globe for the fabrication of the MMNC materials. Amongst them, the stir casting and Powder Metallurgy (P/M) are two prominent routes which play a vital role in development of quality MMNC products with improved structural, mechanical, and electrical properties [2]. P/M technique is used mostly because it yields homogenous product using smaller heat treatment schedule [3].…”
