Recently, the small punch creep (SPC) test, one of the small sample methods, has attracted much attention. However, since the SPC test is a new test, there is a great demand for the accumulation of data to compare with the uniaxial creep test. In this study, SPC tests of A5052 alloy at around 0.7Tm were performed under various loads, and load dependence of displacement velocity were evaluated. The microstructures before and after fracture were observed by EBSD to investigate the microstructural changes and deformation behavior during the tests. The results showed that the displacement velocity and load followed a power law relationship and behaved similarly to the uniaxial creep test.
