英文摘要 | Specimens of silicon carbide (6H-SiC) were irradiated with 5 MeV Kr ions ((84)Kr(19+)) for three fluences of 5x10(13), 2x10(14) and 1x10(15) ions/cm(2), and subsequently annealed at room temperature, 500 degrees C, 700 degrees C and 1000 degrees C, respectively. The strain of the specimens was investigated with high resolution XRD and different defect evolution processes are revealed. An interpretation of the defect evolution and migration is given to explain the strain variation. The mechanical properties of the specimens were studied by using a nano-indentation technique in continuous stiffness measurement (CSM) mode with a diamond Berkovich indenter. For specimens irradiated with fluences of 5x10(13) or 2x10(14) ions/cm(2), hardness values exceed that of un-implanted SiC. However, hardness sharply degrades for specimens irradiated with the highest fluence of 1x10(15) ions/cm(2). The specimens with fluences of 5x10(13) and 2x10(14) ions/cm(2) and subsequently annealed at 700 degrees C and 500 degrees C, respectively, show the maximum hardness value. |
