The relation between mechanical properties and structure of aluminum and magnesium cast alloys at low temperatures

1. The following cast alloys have the best combination of properties in the temperature range 293–20°K: A119 aluminum and VM12 magnesium alloys. 2. A satisfactory level of properties is observed down to a temperature of 77°K in the case of alloys VAl5 and Ml10 alloys. 3. The use of cast aluminum-magnesium alloys Al27-1 and Al8M and the magnesium alloy M15 is permissible down to a temperature of 203°K.
