My research in January:

During the first month of the year I started to conduct experiments. At first I bought 10 kg of magnesium and 50g of calcium. I also used zinc, but it was from supplies of my supervisor. I cast 25g of Mg-Zn4 wt% alloy in the presence of argon atmosphere at 750 oC. During this experiment I used steel mold and graphite crucible. Unfortunately it appeared that I got big pores in this alloy. Conclusion: steel mold has to be avoided or should be heated up before casting.
