This will provide reference for the preparation of heat resistant aluminium alloy materials.with good comprehensive performance.
The elongation of materials decrease first with the increasing tensile temperature, the minimum appears at 250℃.
This phenomenon can be explained by the law of dynamic strain aging (DSA) [4-5]: DSA think that the interaction between solute air mass and dislocation motion enhances the strength of the material at DSA temperature, and affects the strain hardening rate, leads to local plastic instability, the ductility decreases.

The combined flocculating channel is free from internal-external pressure differences throughout the entire flocculating process and therefore, strong materials are not required for construction (for example, plastic materials are sufficient), so the manufacturing costs are is expected to be relatively low and the equipment volume utilization ratio is relatively high.

Introduction Geotechnical engineering is a new branch of science developing rapidly in nearly half of a century in China.
The greater of the density of material, the better of the ability to absorb radiation, By analyzing the ray attenuation characteristics, it is easy to get the micro-mesostructures of rock-like material structural properties.

The Si L2,3 SXF spectrum obtained from a sample annealed at 750°C indicates an interface electronic structure composed with the compound of Cr3Si silicide and other materials, e.g., a ternary compound.
Among transition metals materials of chromium (Cr) and iron (Fe) are interesting for the electrodes such as a Schottky contact because of high electric contact resistance [1-3] compared with other transition metals.
For the sake of discussion, we have shown electron excited SXF spectra obtained from reference materials in Fig. 4: (a) FeSi, (b) β-FeSi2, (c) α-FeSi2 and (d) bulk SiC, where incident electron energy (Ep) is 4keV [5].

Introduction Non-sand concrete well pipe is widely used as deep well dewatering or decompression treatment materials for its low cost, long life and easily being closed after completion of processing.
The main raw materials of prefabricated non-sand concrete pipe are cement, gravel and water.
Cement often chooses ordinary Portland cement PO42.5, stones with limestone as raw materials after mechanical crushing screening diameter of 12 ~ 15mm artificial gravel.
