Abstract: Shape memory behavior was studied in 1932 by ¨ Olander in his study of “rubber like effect” in samples of gold-cadmium and in 1938 by Greningerand Mooradian in his study of brass alloys (copper-zinc). Many years later in 1951 Chang and Read first reported the term “shape recovery”. They were also working on gold-cadmium alloys. In 1962 William J. Buehler and his co-workers at the Naval Ordnance Laboratory discovered shape memory effect in an alloy of nickel and titanium. He named it NiTiNOL (for nickel-titanium Naval Ordnance Laboratory).  Copper, Zinc, Aluminium alloys are formed between 60% to 80% copper, 15% to 30% consists of zinc, 3% to 10% of Aluminium in various proportions.  A Lamellar structure of metallic Al and Brass (Copper-Zinc) foils are introduced for Copper based or Aluminum based metal matrix composite in Muffle Furnace. Since Nitinol (Ni-Ti) shape memory alloy is too expensive when compared with CuZnAl shape memory alloys (SMA) the aim is to prepare CuZnAl shape memory alloys to give the same properties as that of Nitinol. By using Copper, Zinc and Aluminum for preparing CuZnAl based shape memory alloys the composition is kept in the range of Zn 15-30%, Al 3-10 % and rest of Copper. After taking this composition, the heat treatment process for manufacturing shape memory alloys was done in the muffle furnace. Hardness by quenching process has also been done. The prepared shape memory alloys based on Copper, Zinc and Aluminum provides a scope for dense, compact articles having good mechanical properties and other properties associated with the shape-memory effect.
