| Abstract | ||||
| In this work the transient creep, creep recovery and the structure of Cu-2wt%Sn alloy have been investigated. These investigations are conducted in the temperature range, 190-280 oC, under various constant stresses of 258, 322.4 and 386.9 MPa. All the creep and creep recovery parameters show two distinct regions in the used deformation temperature range and confirm a transition point at 240 oC for the examined alloy. The energy activating the transient creep is calculated. The lattice parameter for the cubic copper phase has a minimum value at 240 oC. The best estimate of the transient creep < br />parameters (n and β) as well as the activation energy of creep process (Q) are obtained using the least- squares method. | ||||
