摘要：
The nature of the interaction between scandium and aluminum is the same as that between other transition elements. At the same time, scandium has its own specific features. Comparative studies on the behavior of aluminum-magnesium-lithium system alloys with or without scandium under conditions simulating the welding thermal cycle showed that the alloy containing scandium was characterized by a higher solid solution stability.
