Abstract Scope |
Introduction of rare earth (RE) elements into aluminum (Al) alloys has been captivating the attention of manufactures who are interested in high temperature applications such as engine blocks and pistons. Recognised potential of RE additions such as cerium (Ce) to Al has lead to a new area of research focused on development of new alloys, targeting powertrain applications that require high temperature strength and creep resistance. In an attempt to further improve the mechanical properties of the Al-Ce system, this paper addresses the effects that RE additions have on the microstructure and kinetics of phase evolution during solidification of Al-Si alloys. This research presents the results of in-situ neutron diffraction solidification and SEM/EDS analyses performed for an Al-7%Si-3.5%RE and an Al-18%Si-8%RE alloy. |
