Improvement of surface properties of an Al–Sn–Cu plain bearing alloy produced by rapid solidification
(Elsevier Science SA, 2019-10)
Al–Sn based alloys are widely used as plain bearings in several engineering applications, particularly in internal combustion engines. The microstructures of these alloys are composed by two main phases, α-Al and β-Sn. The ...
Corrosion of nonferrous metals and their alloys
(Hindawi, 2018-05-31)
Corrosion is the result of the interaction of a material (metal) with its environment.
Thecorrosion process depends on the properties of both metal (and alloy) and surrounding environment. Usually, the more important ...
A detailed study of phase evolution in Cu-16 at. %Al and Cu-30 at. %Al alloys under different types of mechanical alloying processes
(Elsevier Science, 2015-03)
The phase stability of Cu-16 at. %Al and Cu-30 at. %Al alloys obtained by a planetary and an horizontal mills was investigated. The analysis was carried out using X-ray diffraction and various transmission electron microscopy ...
Determination of very low concentrations of hydrogen in zirconium alloys by neutron imaging
(Elsevier Science, 2018-05)
Zr-based alloys are used in nuclear power plants because of a unique combination of very low neutron absorption and excellent mechanical properties and corrosion resistance at operating conditions. However, Hydrogen (H) ...
Effect of temperature on the crevice corrosion of nickel alloys containing chromium and molybdenum
(Electrochemical Society, 2015-03)
Chloride-induced crevice corrosion of alloys 625, C-22, C-22HS and HYBRID-BC1 was studied at different temperatures. Crevice corrosion occurred tens of degrees below the reported critical crevice temperatures obtained ...
Stability of the Fe23Zr6 phase in Zr alloys
(Asociación Argentina de Materiales, 2021)
Alloyed with iron (Fe), niobium (Nb) and tin (Sn), zirconium (Zr) is the main element in the Zirlo-type alloys, vastly used as structural elements and as containers of burnable elements in nuclear reactors. Although Zr is ...
Effect of ball milling strategy (milling device for scaling-up) on the hydrolysis performance of Mg alloy waste
(Pergamon-Elsevier Science Ltd, 2020-08)
Ball milling strategy is of prime importance on the hydrolysis performance of Mg alloy waste. The effect of milling device (e.g. Fritsch Pulverisette 6 (P6) and Australian Uni-Ball-II (UB)), milling atmosphere (H2 and Ar), ...
Vacancy-solute interactions during multiple-step ageing of an Al-Cu-Mg-Ag alloy
(Pergamon-Elsevier Science Ltd, 2009-02)
Small additions of Ag and Mg stimulate nucleation of the Ω phase in artificially aged Al-Cu alloys, after which these elements segregate to the Ω/matrix interfaces. In this work, positron spectroscopy results show that ...
From Fe3Si towards Fe3Ge in Finemet-like nanocrystalline alloys: Mössbauer spectroscopy
(Elsevier Science, 2007-02-01)
Nanocrystalline Finemet-type ribbons with different Si/Ge ratio [Fe73.5Si13.5-xGexNb 3B9Cu1 (x = 7, 8, 10 and 13.5)] were studied by means of Mössbauer spectroscopy and X-ray diffraction. The trend to form the non-stoichiometric ...
Determination of Residual Stresses in High Speed Milled Aluminium Alloys Using a Method of Indent Pairs
(Springer, 2009-09)
An improved method of indent pairs is utilised to determine residual stresses in high speed milling specimens of AA 6082-T6 and AA 7075-T6 aluminium alloys. To carry out the measurement procedure, this approach does not ...
