Intermetallic compounds by reductive annealing
… of a new synthetic route to binary and ternary intermetallic compounds, which avoids the need for reaction at very high temperatures, multi-step reactions, reaction under vacuum and/or the synthesis of precursors. The route was adapted from a synthetic route reported for the synthesis of ternary …

Intermetallic phases formed during galfanizing
… with Galfan is to produce a coating which has no intermetallic phases in the coating but this condition is not always achieved. Though it is important, the nature of the intermetallic phases and the mechanisms of their formation and growth during Galfanizing are far from fully understood. The …

Abrasive wear resistance of ruthenium aluminide intermetallic and ferritic steels containing a sigma intermetallic phase
… abrasive wear resistance of ruthenium aluminide intermetallic and ferritic steel containing an iron-chrome sigma intermetallic phase have been investigated in this study. A medium carbon wear resistant steel (MCV) was used in the study to facilitate comparison between wear resistances in the …

Codeformation Processing of Mechanically-Dissimilar Metal/Intermetallic Composites
… was accomplished through the use of a series of intermetallic matrix composites (IMCs) as discontinuous reinforcements in an otherwise conventional metal matrix composite. The IMCs are produced using an in-situ reaction synthesis technique, called the XD™ process. The temperature of the …

Properties and applications of metastable precious metal intermetallic compounds
… has showed that the attractive colours of the intermetallic compounds AuAl₂ (‘purple gold’) and PtAl₂ (‘golden platinum’) can be combined or mixed to produce an interesting colour spectrum. This may be of interest to the jewellery industry. A series of metastable solid solutions could be formed …

Thermal Transport in Strongly Correlated Rare-Earth Intermetallic Compounds
In dieser Arbeit wurden mit Hilfe von Transportmessungen – vor allem mit thermischem Transport bei sehr tiefen Temperaturen – intermetallische Seltenerdverbindungen untersucht. Diese Materialien sind oft durch starke elektronische Korrelationen gekennzeichnet, die zu neuartigen Eigenschaften …

Grain boundary studies in ordered intermetallic compound Ni3 Al
Theoretical and experimental studies of grain boundary structures were carried out to understand the grain boundary properties of Ni₃Al. Using various techniques of transmission electron microscopy, the geometry of grain boundaries was determined from a number of grain boundaries to obtain a …

A resonant ultrasound spectroscopy study of hydrogen-absorbing intermetallic compounds
… used to study four different hydrogen-absorbing intermetallic compounds. A fundamental study of the properties of hydrogen motion within a host metal lattice was undertaken, on two different Cl5 Laves-phase compounds. These results have been obtained by determining the ultrasonic attenuation as a …

Atomic and electronic structure of bulk intermetallic and heteroepitaxially grown surface alloys
… detailed herein, the surfaces of the ordered intermetallic alloy FeAl(110) exhibit surface segregation , which changes the Al concentration in the near surface region. The segregation and corresponding concentration change of Al induces a reconstruction on the surface as a function of …
