Concrete-Filled Steel Tube structure has been widely used in the basic components and the overall structure of behavioral research has made many achievements. There are many advantages of concrete pipe above, but it also has fatal flaws, Stainless steel steel that is the difference[2]. The stainless steel has a beautiful appearance, durability, corrosion resistance, low maintenance costs, good fire resistance and other advantages. New stainless steel pipe concrete structure has both ordinary steel concrete good mechanical properties and excellent durability of stainless steel, can be widely used in buildings and bridges of the marine environment as well as some of the high durability and aesthetic requirements important building structures. Based on the outer stainless steel hollow sandwich - the carbon steel pipe shaft of light pressure test concrete results of load and displacement of the structure, variation of load and strain, and the impact of the empty heart of these parameters.

Complex Deformation

The increased use of metallic biomaterials in contact with blood e.g. for application as coronary stents is steadily resulting in the development of new biomaterials. Conventional bare-metal stents made by stainless steel were reported on adverse reactions against human body and are gradually replaced by coated stainless steel. The new generation of stent requires fundamental improvements at the materials point of view. Although titanium and classical Ti-alloys display superior biocompatibility compared to other metallic materials (stainless steels, Co-Cr), the major drawback of their relatively low ductility (typically 15%-25% of elongation) seriously limits their applications as cardiovascular stents, where large ductility is basically required during the stent deployment procedure and long-term service. In this paper, new titanium alloys with high ductility, a binary Ti-12Mo (wt%) and a ternary Ti-9Mo-6W (wt%) were designed by using a chemical formulation strategy based on the electronic design method called “the d-electron alloy design method”. Both alloys were synthesized and thermo-mechanically treated into beta-metastable state. In tensile tests, both alloys exhibited outstanding ductility of 43% and 46% in total elongation at room temperature, which is almost two times greater than the normal value shown with classical titanium alloys. Optical microscopy and detailed TEM observations on the deformed specimens revealed a complex deformation mechanism, involving {332}<113> mechanical twinning, stress induced plate shaped omega phase and stress induced martensitic (SIM) transformation β-α’’.

Exposure Conditions

In this study, the fire resistance of steel composite beams typically used in building structures was investigated through standard fire and loading tests. For the tests, fire-exposure conditions depending on the steel section shape and load ratio applied to the beams were considered as the test parameters. Based on the test results, the applicability of fire design methods for composite beams recommended in current domestic and overseas fire design codes was analyzed. The results indicate that the current temperature-based design method and reduced flexural capacity method specified by the American Institute of Steel Construction may lead to the conservative fire design of steel composite beams owing to the underestimation of the effects of the fire-exposure conditions and load ratios.

Optimal Cutting Parameters

In order to explore the cutting rule of hard-to-machine material austenitic stainless steel and to optimize cutting parameters, multiple sets of parameters of austenitic stainless steel cutting were schemed out by using uniform design method. Test cutting researches of cutting forces, surface roughness and cutting efficiency with these parameters were conducted under the condition of dry cutting. On this basis, multi-objective optimization model of cutting force and surface roughness applied to austenitic stainless steel had been set up by multiple regression analysis. Variance analysis showed that these formulas have highly significant linear relationship. Verification test is done under the optimal cutting parameters, and the results of cutting forces and surface roughness are in good agreement with the calculated. Turning efficiency is improved by 23.4%, compared with the actual cutting parameters of past production.
