Influence of Trace Elements and Reinforcement Additions to the Liquid Phase Sintering of 2xxx Series Aluminum Alloys

摘要

Sintering of aluminum alloys is usually performed by the formation of a liquid phase. Liquid phase in 2xxx serie alloys is formed from a+Al_2Cu eutectic. In this work, the influence on the liquid phase of trace elements like Sn or Pb, and the addition of one ceramic reinforcement as TiCN, is studied in 2014 alloy supersolidus liquid phase sintering, through the mechanical properties and microstructure study.
