Al-11.5 wt.％Si alloy was modified by Sr and then solidified in different moulds.The results showed that whether or not adding Sr modification agent the electrical conductivities of alloys solidified in the moulds are ranked as follows: graphite mould ＞ copper mould ＞ refractory mould.However, the addition of Sr greatly increases the electrical conductivity of the solidified Al-Si alloy compare with that free of Sr.

It is of both academic and industrial interests to to understand and be able to model how the formation and evolution of different microstructures and textures during and after extrusion.The current w
Bases on a non-superplastic Al-5.40Zn-l.98Mg alloy (wt.％), we developed a new high-strain-rate superplastic alloy by applying Sc and Zr microalloying technology.The new Al-Zn-Mg-Sc-Zr alloy has a maxi
Compared with the conventionally grain-sized materials with the same composition, the nanostructured and ultrafine grained materials possess much higher strength but lower ductility.Some approaches we
The adiabatic shear bands (ASBs) in AM60B magnesium alloy under ballistic impact at a velocity of 1 km.S-1 were studied by means of optical microscope (OM), scanning electron microscope (SEM), and tra
Cu-Al-Cu laminar composite was prepared with cold rolling process and annealing was carried out to study the phase evolution during the annealing process and its effect on the mechanical properties of
Metastable precipitates in 2xxx and 6xxx alloys are needles or elongated plates (laths) along ＜001＞Al directions, locked to the Al periodicity (4.05 (A)).They are effectively bundles of (ideally) pure
Al-Mg alloy is widely known as a typical class-Ⅰ or class-A type solid solution.High-temperature deformation in this alloy has been reported to be rate-controlled by solute drag creep.The solute drag
In order to investigate the effect of cold-rolling and aging on precipitation and recrystallization behavior of Al-Er-Zr alloy, two thermo-mechanical processes containing peak aging+cold-rolling (A+CR
The casting table with lubricating oil and wipe was used in this study, 30T 7055 superhigh strength aluminium alloy with diameter of 582 mm were cast successfully, and the effects of parameters on mel
A horizontal-type twin roll casting method has been popular for producing aluminum alloy strips, however, it is characterized by a relatively low productivity (1～6 m/min).In contrast, a vertical-type
