In-situ 5vol% TiB2/Al–4.5Cu composites are successfully prepared by the salt–metal reactions assisted by improved mechanical stirring. The X-ray diffraction confirms the formation of TiB2 particles, and no cluster or large precipitate of intermediate phases Al3Ti and AlB2 can be traced. Mechanical stirring can reduce the large agglomerations and finally eliminate them when the speed rises to 540rpm...
Summary form only given. Multiferroics have attracted considerable attention recently because of their fascinating physical behaviors and potential applications. BiFeO3 is one of the well-known multiferroic compounds displaying coexistence of ferroelectricity and antiferromagnetism [1]. The BiFeO3 properties in nanosize were especially helpful for understanding the foundational ferroelectric and magnetic...
