Aluminum compositesi and Fe2B
Aluminum compositesi and Fe2B
(OP)
Hi friends,
I want to study aluminum composites and I'm interested in Fe2B particulates within the aluminum matrix. Fe2B is
a hard boride phase and used for hardnening of the steel surface. Besides Fe2B powders are very cheap and easy to find. But there is no study in literature. Is it harmfull for the properties of the aluminum composites? May the Fe2B powders find an application in aluminum sintered composites? or not? I m waiting for your comments, please.

RE: Aluminum compositesi and Fe2B
Particles would usually be measured in micrometres; you might get more interesting results for nanoparticles or interesting shapes, if available.
RE: Aluminum compositesi and Fe2B
Fe2B seems to have a modulus of 355 GPa (see http://www-brs.ub.ruhr-uni-bochum.de/netahtml/HSS/...). This is not far off Al2O3 which is probably about 380 GPa and silicon carbide which seems to vary between 220 and 420 GPa.
https://www.jim.or.jp/journal/e/pdf3/43/11/2838.pd... has SiC reinforced Al alloy.
Page 19 of "Metal Matrix Composites in Industry: An Introduction and a Survey, Volume 1" has some data on Al2O3 particulate reinforced Al:

NASA TM 107276 "Micromechanics for Particulate Reinforced Composites" has passably accurate micromechanics formulas in it (the predictions match the measured data given in the above quite well).
