        摘要：Gr（C）/Mg composites were prepared by vacuum pressure infiltration. No reaction product was observed at the interface in Gr/Mg composite, but some precipitates, identified as γ Mg17Al12, can be found. The various shape and size of precipitates are related to different casting conditions, especially to fibre preform temperature Tp. The Al content at the interface in C/Mg composite is twice higher than matrix. The possible reason is discussed.

        摘要：When 5% addition composed basically by Mn, Cr, RE is added to ZL108 alloy containing 1.2% Fe, Iron phase in the alloy becomes spheroidized, block or plum blossom like shape as originally they were acicular or flake shape. When S is added to the alloy alone the form of Iron phase is short pole like. If 3% addition is added first and then S is added, Iron phase becomes very small spheroidal or block shape, the form of Iron phase could reach the first grade according to GB3508-83.

        摘要：Effect of the surface treatment of hollow micro balls used as foaming agent on improving wettability with molten Al and increasing porosity and pore uniformity has been experimentally studied. The results show that hollow microballs by surface actived treating, compared with untreated hollow microballs, can be easily dispersed in the molten Al, and the pore size and dispersed uniformity are improved, and foaming time is enlonged, and foaming process is more beneficial to manipulate. The porosity increases from 60% to 68% or 72% as the balls are steeped in Na 2CO 3 aqueoas solution or treated by nickel plating, respectively.

        摘要：This article is concerned with the experimental determination of mechanical and fracture mechanical properties （under static and cyclic loading） of the aluminum alloy GD AlSi9Cu3, changed die casting process parameters and quenched in water as well as aged. The data obtained from the tests are then used to assess the castings with respect to failure risk.

        摘要：A series of temperature measurements were conducted for Low Pressure Die Casting （LPDC） die of aluminum wheel. The temperature distribution and changing pattern in the die castings were obtained. Several factors which affect die temperature were analyzed, and their effects on the temperature distribution were tested and verified. The results showed that the maximum and minimum temperature of the die in a cycle was about 550 ℃ and 400 ℃ respectively. The variations of temperature in most places of the die were between 20 ℃ and 70 ℃. The results are significant for LPDC die design and LPDC simulation.
