dispersive spectroscope (EDS). The products from the reaction between SiC and titanium aluminides were determined by X-ray diffractometer (XRD) and the thermodynamics of the reaction was investigated.... Intermetallic multi-layers are determined to be Ti3Al, TiAl and TiAl3. SiC particles react with titanium aluminide during reaction annealing to form Ti3AlC, TiC, Ti5Si3 and Ti3SiC2.Key words:titanium......

Preparation of Rapidly Quenching (Nd,Pr)12(FeCoZr)82B6 Alloy and Magnetic Properties of Bonded Magnets 查五生1,涂铭旌1,高升吉1,刘颖1 (1.College of Material Science & Engineering,Sichuan University,Chengdu...(FeCoZr)82B6 bonded magnets were investigated by using sub-overquenching and post annealing method. The quenching rates, annealing temperatures, and annealing time directly influence the microstructure......
precipitates (interfacial reaction product) decrease with the heat input decreasing. When the heat input lowers to 30 J/mm, the formation of needle-like Al4C3 can be prevented. The distributions of SiC... the porosities in the TIG and MIG welds[2,3,5]. During welding, serious interface reaction between SiC particles and Al matrix occurs and plate-like Al4C3 precipitates form, which are very brittle......
