英文摘要	The dense Al2O3-ZrO2 ceramic composite prepared by spark plasma sintering was irradiated by 500 keV He ions with different fluences and temperatures. The microstructural evolution and mechanical properties were investigated. The results showed that peak broadening and shifts at RT revealed by GIXRD and Raman are associated with damage induced microstrain and formation of point defects. The recovery at 500 degrees C suggested the reduction of irradiation induced damage. Compared with alpha-Al2O3, t-ZrO2 exhibited a reverse trend in lattice parameters change and lattice expansion. Many helium bubbles with oblate and ribbon-like shape were mainly formed in alpha-Al2O3 grains at He concentration peak at 1.0 x 10(17) ions/cm(2). With increasing of fluence at RT, ribbon-like helium bubbles developed into microcracks at 4.0 x 1017 ions/cm(2). Though evident structural changes, no full amorphization was observed at 4.0 x 10(17) ions/cm(2). Formation of ribbon-like bubbles and microcracks is the main mechanism for degradation of mechanical properties of irradiated Al2O3-ZrO2 composite.
