The effect of forging on the microstructure and texture evolution of a high Nb containing Ti-45Al-7Nb-0.3W(at.%)alloy was investigated by X-ray diffractometer(XRD),scanning electron microscopy(SEM),and transmission electron microscopy(TEM).The results show that the as-cast alloy is mainly composed of α_(2)/γ lamellar colonies with a mean size of 70μm,but the hot-forged pancake displays a near duplex microstructure(DP).Kinking and bending of lamellar colonies,deformation twinning and dynamic recrystallization(DRX)occur during hot ***,dense dislocations in theβphase after forging suggest that the high-temperature β phase with a disordered structure is favorable for improving the hot-workability of the *** the common TiAl casting texture,the solidification process of the investigated as-cast alloy with high Nb content is completely via the β phase region,resulting in the formation of aγ fiber texture where theγ aligns parallel to the heat-flow *** comparison,the relatively strongand weaktexture components in the as-forged alloy are attributed to the deformation *** annealing,static recrystallization occurs at the twin boundary and intersections,which weakens the deformation texture.

Ordered mesoporous materials have received great attention due to their well-defined pore structures and potential applications in catalysis, adsorption, separation, drug delivery, etc. Although various compositions of mesoporous solids have been successfully prepared, the preparation of crystalline non-metallic oxyacid salts with ordered mesoporosity remains a major challenge. Herein, we report the synthesis of a mesoporous solid acid crystalline boron phosphate（BPO4） catalyst with a bicontinuous shifted double diamond（SDD） hyperbolic surface structure. The BPO4scaffold was obtained by synergistic selfassembly in a mixed solvent of water and tetrahydrofuran using the diblock copolymer poly（ethylene oxide）-block-polystyrene as template and phosphoric acid and orthoboric acid as inorganic sources. The structure consists of two sets of diamond networks adjacent to each other with a mesostructural scale tetragonal symmetry（space group I41/amd） with unit cell parameters of a =80 nm and c = 113 nm, which affords the scaffold a specific surface area of 44 m2/g. As a solid acid catalytic material, the SDD BPO4scaffold exhibited excellent catalytic activity at room temperature with a conversion of furfural to 2-（dimethoxymethyl）furan over 70% and can be reused after recovery without serious loss of activity. In the propane oxidative dehydrogenation reaction, SDD BPO4demonstrated high olefin productivity and selectivity while maintaining high reaction rate. This study provides ideas for the preparation of ordered mesoporous crystalline catalytic materials and demonstrates their potential for practical applications.
