Strategies for improving ductility of ordered intermetallics

open access: yesProgress in Natural Science: Materials International, 2016
Ordered intermetallics possess attractive high-temperature properties; however, low ductility and brittle fracture limit their use as engineering materials in many cases.

Photoemission of intermetallics

Journal of Magnetism and Magnetic Materials, 1987
Abstract Photoemission and spin-resolved threshold photoemission data on magnetic intermetallic compounds as e.g., MnP and NiMnSb are reviewed. New data on PtMnSb(100) are presented and discussed in terms of a calculated band structure. Recent spin- and angle-resolved photoemission data on monolayer films of Gd on Fe(100) have allowed to test the ...

Intermetallic: A Pseudoelement for Catalysis

Accounts of Chemical Research, 2017
A clear correlation between electronic structure and CO2 selectivity for steam reforming of methanol (SRM) was obtained with PdZn, PtZn, NiZn, and PdCd intermetallics on the basis of experiments and calculations. In order to rule out the effects of oxide supports, the intermetallic powders were simply prepared by alloying in an arc furnace followed by ...

Intermetallics for permanent magnets

IEEE Transactions on Magnetics, 1993
Going back as far as 1931, it is shown by the examples MnAl, Fe-Nd, Fe-Nd-B, and Fe(-Ti)-Sm how the history of permanent magnet materials might have evolved differently if hints had been heeded that were discernible long before a particular magnet development actually began.

Oxidation of Some Intermetallic Compounds and Intermetallic Matrix Composites

MRS Proceedings, 1994
AbstractOxidation resistance (1000-1400°C) was characterized for intermetallics M2Al, M3Al, M2Cr, and M5Si3 (M=Nb, Nb+Ti), and metal-toughened intermetallic composite systems. Aluminides were poorest in oxidation, and Laves phases were best. Substitution of Ti for Nb was beneficial for each intermetallic. Addition of metal to produce two-phase castings

Interdiffusion in Intermetallics

Metallurgical and Materials Transactions A, 2013
Recently, Tiwari and Mehrotra asserted that the vacancy flux in interdiffusion is driven by a vacancy concentration gradient and also that interdiffusion in intermetallics cannot proceed by the six-jump cycle, triple defect, and antistructural bridge mechanisms.

Multiphase intermetallics

Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1995
Abstract Ordered intermetallic compounds, notably the aluminides of nickel, titanium, iron and niobium, have been under intensive investigation for the past two decades as prospective load-bearing materials for high temperatures, with special emphasis on aerospace applications.
