1973.全球钢铁制造市场报告(2014-2018年)
[黑色金属冶炼和压延加工业,金属制品业] [2014-09-02]
Steel is the main engineering material used in the manufacturing process of the Construction, Automotive, Transport, Power, Mechanical Machinery, Metal Goods, and Domestic Appliances industries. It is also the main material used to deliver renewable energy such as solar, tidal, and wind. Steel is composed of iron, carbon, impurities, and alloying elements that determine its properties. Based on its properties, steel is classified into various types such as carbon steel, alloy steel, stainless steel, and tool steel. Steel provides various advantages to the products in which it is used such as strength, durability, corrosion resistance, hardening ability, formability, welding ability, and ductility.

1976.用于髋关节植入物应用的生物医药联合合金发展
[金属制品业,医药制造业] [2014-07-29]
The development of cobalt alloys for the development of HIP implants has been evolving overtime. Accordingly, in this work an overview of the main microstructural factors that impact the mechanical properties, as well as the effect of interstitials such as carbon and nitrogen. In addition the role alloy pre-straining and heat treating on the amount of ε-martensite and on the exhibited mechanical properties is described. In general, it is shown that as the amount of ε-martensite exceeds 60 vol. percent, the alloy ductility is drastically reduced as the HCP phase becomes dominant in the matrix.

1977.可逆的石墨烯加氢金属接触
[化学原料和化学制品制造业,金属制品业] [2014-07-28]
We use x-ray spectroscopy and density functional theory to investigate the hydrogenation-induced electronic structure changes in graphene on Pt(111). The atom-specific properties of the spectroscopy allow for a direct projection of the band structure onto the carbon atoms; this was compared with the calculated density of states. Instead of the generally expected band opening behavior, we observe states at the Fermi level in the carbon-projected density of states. Hydrogenation is accompanied by pinning of the graphene to the substrate through the formation of local CPt bonds which cause the graphene layer to become metallic upon hydrogenation.

1978.2012年2月9日密西根州南菲尔德对于汽车轻量化实施先进高强度钢车间的关键技术差距
[金属制品业,汽车制造业] [2014-07-27]
The six important technical areas were selected by the workshop organizing committee, a group of experts from the auto and steel industries, and scientists from several National Laboratories. These selections were based on areas where there were known technical gaps, which if closed would have high impact on accelerating vehicle lightweighting with AHSS. The selected areas were: Steel Development, Fracture, Plasticity, Delayed Fracture/Hydrogen Embrittlement, Modulus Characterization and Joining. The main output of the workshop is contained within the breakout session reports, which summarize the technical requirements, engineering gaps and research needs. The breakout session reports are included below in the main workshop report.

1979.射击喷丸钢样品疲劳试验中的残余应力演化过程
[金属制品业] [2014-07-27]
Directly-generated compressive residual stress has become a widely used surface modification technique. Intentional residual stress in solid materials can be produced by different surface compression methods. It is well known how residual stress field is influenced by the parameters of the shoot peening but only few articles address the phenomenon about the evolution of the stress during the operation of the machine component. The literature on residual stress decrease caused by fatigue load is scarce and the kinetics of this mechanism is not yet investigated. The present work reports on the examination of the effect of the fatigue load on compressive residual stress strengthened specimens. Investigations have been conducted at three stress levels. Residual stress data have been measured by X ray diffraction method before fatigue load and measurements have been repeated after defined fatigue cycles.

1980.金属加工控制系统的性能监控
[信息传输、软件和信息技术服务业,金属制品业] [2014-07-27]
The number of control loops used in process industry is growing continuously, whilst manpower is being reduced. Consequently even companies that have embraced new control technologies struggle to maintain satisfactory performance over the long term. Numerous investigations have shown that the performance of control systems in the process industries is not satisfactory, as mentioned in Chap. 1. This particularly applies for the steel industry, where it is the norm to perform controller tuning only at the commissioning stage and then never again. A loop that worked well at one time is prone to degradation over time unless regular check and maintenance is undertaken.
