Due to the shape memory effect (SME) of shape memory alloy (SMA) fiber and the different thermal expansion coefficients between the constituent materials, internal stresses are induced when a single prestrained SMA fiber–matrix composite is heated. To avoid interfacial debonding between the SMA fiber and the epoxy matrix and to take full advantage of the properties of SMAs, it is necessary to investigate...
Ba 0.6 Sr 0.4 TiO 3 –MgTiO 3 composites were prepared by reaction of BST powders with molten MgCl 2 at various MgCl 2 /BST molar ratios at 600 and 800°C in air. The products were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). It is shown that the ceramic composites have a relaxor-like ferroelectric transition as MgTiO ...
