The uniaxial tension (UT) tests and advanced expansion due to compression (A-EDC) test have been applied to examine the deformation behavior of Zr-1.8Nb cladding tubes, respectively. The differences of mechanical properties and microstructure evolution between UT test and A-EDC test have been compared and discussed.
