“…than that of the unmodified sample. The diameters of the pores at the fracture surfaces are given in detail as follows: 100-140 lm, [8][9][10][11][12][13][14][15][16][17] lm and 25-60 lm for unmodified alloy, modified alloy with 0.6 wt.% Er and 0.9 wt.% Er, respectively. It is clearly concluded that the pore diameter of the alloy is significantly reduced by modifying with Er.…”

Abstract. Inappropriate air vent design always induced porosities in thin and complex shape of high pressure diecasting (HPDC) products. Chill block installation was preferred to improve permanent molds for reducing porosities. There were not regular to obtain an appropriated chill vent from this method unless an experience of mold makers. This research was performed to investigate and evaluate the chill block performance in the HPDC mold of motorcycle fuel caps. The HPDC mold of the thin and complex shape product without chill vents was improved by inserting of chill blocks. The motorcycle fuel caps of molds with and without chill vents were compared to verify size and position of porosity defects. Furthermore the HPDC simulation using the finite element analysis (FEA) had been performed according to the physical experiment. The FEA results were compared and in agreement with the experimental data. Therefore an improvement of the HPDC mold should be used FEA to obtain the best way of the air vent design.

“…Significant progress has been seen in casting capability and understanding of the relation between the microstructure and mechanical properties of AZ91. These relations were established experimentally [2][3][4] and modeled for quantitative prediction [5][6][7]. The microstructure of AZ91D consists of the primary α-Mg and a highly divorced eutectic consisting of α-Mg and Mg 17 Al 12 .…”

In the current study it was observed that the offset yield point of Mg-9%Al-1%Zn alloy was strongly influenced by the connectivity of Mg 17 Al 12 . It was suggested that an increase in the fraction of Mg 17 Al 12 from 8% to 11% could lead to the formation of a Mg 17 Al 12 network which resulted in a higher offset yield point. In addition, it was observed that elongation to failure of the Mg-9%Al-1%Zn alloy strongly depended on the fraction of Mg 17 Al 12 . Moreover, the apparent toughness showed a strong inverse relation to the secondary dendrite arm spacing. This approach might be extended to forecast the behavior in other magnesium alloys forming a network of the Mg-Al phase.
