Fractural Research on Ti2AlC/TiAl Compound Materials

Abstract

The SEM images of Ti2AlC/TiAl materials with different samples showed different fractal dimension.In Multi-fractal spectrum, the parameter is calculated by the multi-fractal spectrum theory. Without r=0.00625, giving rise to the small fluctuate, lnχq(r) and lnr shows the well linear relationship in spite of the value of q. τ (q) and q show nonlinear relationship and the protuberance existed in q∈[-3,-1], D(q) and q turn to be more steep, at last the clock shape relationship between the α and f(α) reveals the good symmetry of spectrum, uneven distribution of the fracture, multi-fractal feature clearly.
