Trans. Nonferrous Met. Soc. China 20(2010) s744-s748 Microstructure of semi-solid ADC12 aluminum alloy adopting new SIMA method WANG Zhen-yu(王振宇), JI Ze-sheng(吉泽升), SUN Li-xin(孙丽鑫... microstructure of ADC12 aluminum alloy containing spherical solid particles was studied. A new strain-induced melt activation (SIMA) process was proposed. In the treatment, chips were cut from ADC12......
to reduce SiO2 and Fe2O3 in molten aluminum alloys yield free Si and Fe, respectively. Also, Mg reduces Al2O3. At 1 000 K, using the thermodynamic data in Refs.[11], the Gibbs free energy changes...

of Technology, Lanzhou 730050, China Received 28 July 2006; accepted 15 September 2006 Abstract: CO2 laser beam welding of aluminum alloys with different thicknesses was carried out. The influences... blanks 1 Introduction In recent years, aluminum alloys are extensively used in transportation with increasing demand for light-mass structures. The main reason is wrought aluminum alloys provide......
; 1 Introduction Aluminum alloys have been the primary materials for structural components of military aircrafts, helicopters, amphibians, etc for several decades. This may attribute to the low density of aluminum in mass- critical application[1]. 2519 aluminum alloys that is used as armor plates have good weldability, acceptable......

of their high strength, good toughness and excellent properties [1–4]. In order to satisfy the demand for high-strength aluminum alloys and improve the safety of airplanes, ALCOA corporation developed...-equilibrium crystallization. These factors weaken the workability of the cast structure and ultimately affect the mechanical properties of aluminum alloys [11–14]. Therefore, in order to obtain excellent......
