    Abstract: The chromium mesoporous materials have been used in many catalytic reactions. Some studies have been devoted to determining the nature of chromium species and to characterizing the chemical structure. The different chromium species depend on synthetic methods and the support used. In this work we prepared mesoporous SBA-15 supported chromium materi... Show More

    Abstract: The kinetic glass transition of the Vit1 (Zr41.2Ti13.8Cu12.5Ni10.0Be22.5) bulk metallic glass (BMG) was calorimetrically studied by using the differential scanning calorimetry (DSC). A wide range of heating rate, q=0.5~100 K min-1, was adopted in the calorimetric experiments. The apparent values of the glass transition temperatures were determined ... Show More

    Abstract: The possibility of two pass welding for TA2/T2 bimetallic sheets joint with laser-TIG hybrid weldings was studied. Laser-gas tungsten arc welding (TIG) hybrid welding of TA2/T2 bimetallic sheets has been applied using BCuP-2 wire as filler metal. A new welding process for TA2/T2 butt joint was introduced on the basis of the controlling the formatio... Show More
