Comparative analysis of primary aluminum and recycled aluminum on energy consumption and greenhouse gas emission

Abstract: Based on life cycle assessment(LCA),a quantitative analysis of energy consumption and greenhouse gas emission caused by primary aluminum and recycled aluminum in China in 2008 was carried out.The main reason for the gap between China and international average level was found out through the comparison.The results show that,compared to the status of 2003,the energy consumption of primary aluminum production has reduced by about 16%.The greenhouse gas emission has declined by 21% and a remarkable achievement in energy saving has been made.The global warming potential(GWP) also reduce sharply.The results show that the aluminum industry has made remarkable achievement in energy saving and emission reduction.The energy consumption and GWP of primary aluminum in China are still higher than that in European and the world average,mainly due to coal-based energy structure.The energy consumption of recycled aluminum production is only 4.86% of the primary aluminum,the GWP is only 1/24 of the primary aluminum.Compared with the foreign level,the main difference in recycled aluminum is that the energy consumption is higher in transportation and high carbon emission of fuel.

Research, development and application of wrought magnesium alloys

Abstract: The properties and applications of wrought magnesium alloy were reviewed. The research and development of wrought magnesium alloys, including some new technique such as rapid solidification processing, were introduced. The theory of alloy formation and effects of alloy elements, especially rare earth elements, were discussed. A high strength , good ductility and various properties of magnesium alloys can be obtained through the combination of plastic deformation and heat treatment. The wrought magnesium alloy will be a hopeful and important commercial light structural material in the 21st century.

Dynamic problems in deep exploitation of hard rock metal mines

Abstract: The energy storage characteristics of hard rock in metal mines under high stress was described from the deep mining environment.And the inevitable trend of continuous mining methods in the future with the increase of exploitation depth of metal mines was also analyzed.For hard rock in metal mines under high stress,the dynamic disturbance caused by continuous mining was conducted on it,which can be considered as a mechanical problem coupled static and dynamic loads.On this basis,three key dynamics problems were analyzed by using the theory of coupled loads as follows: the system disturbance and rock burst in deep metal mines exploitation,mine earthquake and drift instability caused by blasting in deep mines,energy release and orderly regulation in deep metal mines exploitation.Theoretical analysis and engineering practice proved that several dynamics problems in deep metal mines can be explained by using the theory of coupled static and dynamic loads,which will provide some engineering practice guidance for deep exploitation.

Quantification of microstructural features in(α+β) titanium alloys

Abstract: Based on the three-dimensional stereology and graphics softwares,a process for quantifying the microstructure of(α+β) titanium alloys was developed,the parameters include,thickness,volume fraction,morphology,and orientation of a-laths,colony size,grain size,colony size,Feret ratio ofα-laths,mean diameter and volume fraction of primaryαphase.The developed models and methods are verified with some examples.The results show that the process is fairly accurate to build a robust expert system to model the correlation between the microstructure and property of titanium alloys.
