melting pointmelt growthsynchrotron white beam X-ray topographyDirect observations of the melt growth process of aluminium crystals have been made using synchrotron white beam X-ray topography. It is shown that static small angle grain boundaries can act as sources of lattice dislocations when they ...
In the LJ case, for example, the intermediate fluid states which arise in integrating from the LJ fluid to the fullab initiodescription of Al are found to freeze. Ultimately, consistent results are obtained. 展开 关键词: Ab initio calculations Aluminium Free energy Melting Liquid solid interfaces...
melt·ing point (mĕl′tĭng) The temperature at which a solid becomes a liquid. For a given substance, the melting point of its solid form is the same as the freezing point of its liquid form. The melting point of ice is 32°F (0°C); that of iron is 2,797°F (1,535°C...
This theory may be briefly stated as follows: When the aluminium- silicon alloy is raised to a temperature considerably higher than its melting point, it is probable that the silicon and aluminium are in true solution. When solid the greater portion FIG. r.-g·86 per cent. Si, 0·45 ...

The purity of the aluminium affects the measured viscosity values and we recommend a value of between 1.0–1.4 mPa·s for the pure element at the melting point. Although studies of the viscosity of aluminium alloys are limited, the effects of elemental additions to the alloy are similar to ...
AlSi7Mg, AlSi12, and other series of alloys, of which the research of AlSi10Mg alloys is the most in depth. The AlSi10Mg alloys belong to the Al-Si alloys and have a composition close to the eutectic point. The melting point of ABAs is low, and the solidification range of solid–liqu...
