Originální abstrakt

Solid state mixing, such as mechanical alloying (MA), represents technologically reasonable economical processing method how to achieve homogenous distribution of hard particles in composite microstructure. The advantage of working at ambient temperatures, without a process control agent (PCA), opens new route for the preparation of advanced materials. The use of mechanical alloying includes several advantages, namely control of the particle size or the compatibilization of hard immiscible blends. The aim of the current work is to prepare TiB2 phase dispersion in aluminum matrix using mechano-chemical processing. For this purpose a mixture of aluminum, boron trioxide and titanium powders were subjected to high energy ball milling. The microstructural and phase analyses of powders particles after different milling times and after addition of aluminum (two-step mechanical alloying) was conducted by using scanning electron microscopy (SEM), X-Ray diffractometry (XRD) and scanning differential calorimetry (DSC). The results indicate that two-step milling method led to the production of aluminum matrix composite with a small amount of fine TiB2 particles distribution.
