Semi-melt forming of functionally graded material (FGM) was investigated to identify the optimum operating temperture. In this paper, we applied online wavelet analysis to the device, and detected a discontinuity of deformation of FGM with temperature increase. The idea was confirmed to be suitable from microstructual observation. We developed a useful semi-melt forming system for refining micro-structure of FGM, which implove of mechanical properties.
