	1	Effects of P+Cr complex modification and solidification conditions on microstmcture of hypereutectic Al-Si alloys by wedge-shaped copper mould casting显示文摘Large and segregated primary Si particles may drastically decrease the mechanical properties of Al-Si alloys. To solve this problem, a P-Cr complex modif ier was added into the alloy, and the effects of P-Cr complex modification and solidification conditions on the microstructure of hypereutectic Al-Si alloys casting produced in wedge-shaped copper mould were studied. The thermal analysis technique was applied to calculate the cooling rate during solidification. The microstructures were observed by means of optical and scanning electron microscopies. Results showed that the primary Si segregates in the as-cast hypereutectic Al-Si alloys. The segregation of primary Si can be inhibited by adding a P+Cr complex modif ier and increasing the cooling rate during solidif ication. The ref inement of primary Si particles by P+Cr complex modif ication is due to the formation of CrS i2 and AlP particles which act as the heterogeneous nuclei for the primary Si phase. The segregation of Si was also inhibited through the adherence of heavier CrS i2 particles to the primary Si particles.

	2	振动条件下的晶粒弥散细化效应及其能量判据显示文摘采用透明模型合金NH4Cl-70%H2O考察不同振动条件下激冷表面的激发形核特性及晶粒剥离行为。实验结果表明:振动频率f一定时,晶粒的剥离速度与细化程度随振动加速度a的增加而增加。基于能量的定义用来描述实验中振动参数和能量之间的关系,实验发现晶粒的细化效果存在能量准则,并给出细化晶粒的优化参数和判据为a2/f≥200m2/s3。	张莹王猛林鑫黄卫东	2011	铸造技术2011，32，12：	2
