Microstructural and Mechanical Properties of Cu-based Alloy Manufactured by Self-propagating High-temperature Synthesis Method
Microstructure and properties of Cu1-xZn1-yAl1-z ranging through (0.29<X<0.30; 0.74<Y<0.75; and 0.83<Z<0.96) alloys obtained by the self- propagating high-temperature synthesis (SHS) were examined. The microstructural and mechanical properties were examined, respectively by X-ray diffraction, tensile tests and Brinell hardness and at last by scanning electron microscopy (SEM). The obtained results showed that the modification of composition lead to the formation of new phases. Therefore, this microstructure affects strongly the mechanical properties of the selected samples.
Cu-based shape memory alloys are the most promising in practical use because of their low price and high recovery force (only secondary to Ni-Ti alloy). Among the Cu-based shape memory alloys (SMAs), Cu-Zn-Al alloys have been selected in the present study. Properties linked to shape memory behavior of Cu-Al-Zn alloys, like martensitic transformation and shape memory effect, have been thoroughly researched. Additionally, the properties like corrosion behavior, microstructure and mechanical properties of selected Cu- Al-Zn alloys have been investigated.
