Al-Fe(-Si) model wrought alloys are prepared which are cast at three different cooling rates on a laboratory scale. In-situ SEM observation of tensile tests has been used to observe damage behaviours of coarse intermetallic compound (IMC) particles; AlmFenSip and AlmFe which are usually observed in practical wrought aluminium alloys. Particular attention is given to the chemical composition, size and aspect ratio of each broken particle. AlFeSi particles close to Al8Fe2Si1 and Al10Fe3Si3 are formed by metal mold and Graphite mold castings, respectively, and AlFeSi particles with various composition ratios are formed by furnace cooling, then being transformed into AlFe3 by subsequent long exposure at 858 K. Almost all of the AlFeSi particles formed during the metal and Graphite mold castings remain intact, while other AlFeSi and AlmFe particles are damaged extensively. Factors affecting the in-situ strengths of the particles are discussed.
