| Abstract: | Impression creep method has been used to study the creep behaviour of Pb-Sn eutectic alloy of two different grain sizes, viz., 3.4 and 7.5 µm in the temperature range of 30-125°C. The deformation response of the fine grained material conformed to regions II and III of a typical sigmoidal behaviour of a superplastic material. The strain rate sensitivity index values determined for region II, 0.43-0.55, were also indicative of superplastic behaviour. In coarse grained material, superplastic behaviour was seen only at higher test temperatures. These showed lower values of strain rate sensitivity index, namely 0.21-0.45. It is concluded that the impression creep technique is attractive for characterising superplasticity when only a small volume of material is available. |
