However, the significant disparity in plasticity between the D019-α2 and L10-γ phases greatly affects TiAl alloys' service behavior. This study investigates the internal strain accumulation in the α2 and γ phases of an extruded Ti-45Al-8Nb-0.2C alloy during compression at 900 °C and the subsequent stress relaxation behavior during annealing at 850 °C, using in situ synchrotron high-energy X-ray diffraction (HEXRD). During compression, the γ phase starts to yield plastically at approximately 410 MPa true stress, progressively shifting the load to the α2 phase and generating high residual stress in the α2 phase after deformation. However, annealing at 850 °C for 30 min only partially relieves the residual stress in the α2 phase, with the relaxation rate decreasing substantially after the first 10 min. Furthermore, when the true stress reaches 790 MPa during compression, the α2 phase undergoes rigid-body rotation to accommodate the plastic deformation of the adjacent γ phase, initiating texture evolution that ultimately forms a distinct fiber texture.

T1 - Soft x-ray emission spectroscopy studies of the electronic structure of silicon supersaturated with sulfur N2 - We apply soft x-ray emission spectroscopy (XES) to measure the electronic structure of crystalline silicon supersaturated with sulfur (up to 0.7 at. %), a candidate intermediate-band solar cell material. Si L2,3 emission features are observed above the conventional Si valence band maximum, with intensity scaling linearly with S concentration. The lineshape of the S-induced features change across the insulator-to-metal transition, indicating a significant modification of the local electronic structure concurrent with the change in macroscopic electronic behavior. The relationship between the Si L2,3 XES spectral features and the anomalously high sub-band gap infrared absorption is discussed.

As a strategy for urban flood control, low impact development (LID) practices focus on promoting the infiltration and detention of stormwater runoff. A modelling-based study was conducted to analyse LID performance in urban flooding reduction. Two-dimensional simulations were conducted to visualise the flood risk under different precipitation scenarios and LID schemes. An integrated evaluation system based on life-cycle cost analysis, the analytic hierarchy process, and regret decision theory were applied to assess the LID performance in multiple aspects. The results indicated that the LID practices achieved runoff control and flood mitigation to some extent, especially under mild rainfall events. According to the integrated evaluation, urban flooding risk could be sufficiently reduced with the LID combination of bioretention, infiltration trenches, and rain barrels in the given area.
