Abstract

Laminated CuAl10Fe3Mn2-intermetallic phases composites have been produced in vacuum through reactive bonding at 875 °C using bronze and titanium foils with thickness 0.6 and 0.1 mm, respectively. During fabrication the titanium layers reacted completely and formed Ti2Cu, TiCuAl and TiCu2Al intermetallics. This paper summaries the microstructural changes which take place in laminated composites during heat treatment. Also the mechanical properties and fracture behavior of the heat treated composites were examined through hardness measurements and tensile tests. The results of investigations indicated that tensile properties of the composites strongly depended on the type of applied heat treatment (especially on aging temperature). Upon completing examinations one can define the heat treatment conditions necessary for obtaining optimum properties of laminated CuAl10Fe3Mn2-intermetallic phases composites.
