AB  - Iron based alloys are the family of bulk metallic glasses (BMG) with a very high melting temperature (Tm) and highest critical cooling rates (Rc~103K/s) necessary to suppress nucleation of crystals during the casting process. Consequently, this class of BMG is the most difficult for preparation in a thick form. The rods of Fe-based bulk metallic glasses with the nominal composition Fe65.5Cr4Mo4Ga4P12C5B5.5 were cast by melt injection into a 1.5 and 1.8 mm diameter copper molds. DTA thermogram shows wide supercooled liquid region between crystallization temperature (Tx) and glass transition temperature (Tg) in the as-cast state Δ Tx = Tx - Tg = 57 K. The thermal stability and crystallization processes were investigated by non-isothermal differential thermal analysis (DTA) and X-ray diffraction (XRD). Thermal stability was discussed in terms of the width of supercooled liquid region ΔTx. Calculation of kinetic parameters of crystallization process was preformed by nonisothermal measurements results using Kissinger method.

AB  - Hydroxyapatite (HAp) was modified by the action of various hydrophobic agents based on silicon-containing compounds. The influence of the type of applied agent on the thermodynamic and kinetic parameters of the cross-linking of poly(dimethyl siloxane)/HAp composites was investigated. All the modified HAp particles became hydrophobic and these samples were used to synthesize the polysiloxane/hydroxyapatite composites (PDMS/HAp). The possible modes of interaction between the hydroxyapatite and hydrophobing agents were discussed. The most probable interaction between hydroxyapatite and the applied hydrophobing agents is hydrogen bonding. PDMS/HAp composites were formed directly in the cell of the DSC and cross-linking was investigated in situ. It was determined that the introduction of hydroxyapatite into polysiloxane matrices changed the enthalpy of cross-linking, as well as the activation energy of cross-linking and reaction order, while the introduction of modified HAp led to thermodynamic and kinetic parameters more similar to those of the cross-linking of unfilled elastomer.
