Liquid metal corrosion/erosion investigations of structure materials in lead cooled systems: Part 1

In future lead cooled nuclear power systems the heavy liquid-metal pump will be placed in the hot temperature region of the reactor. This combines corrosion problematic at elevated temperatures with erosion at the impeller of the pump. Several steels designed for conventional mechanical high loaded pumps and the SiSiC have been tested in oxygen containing stagnant lead (10⁻⁶ and 10⁻⁸ wt%) at 550 and 600 °C for 2000 and 4000 h in the COSTA-facilities. Only SiSiC shows no influence by the liquid metal. No dissolution attack occurs at cast iron steels but inner oxidation takes place. NORILOY shows no dissolution attack. All other steels are attacked by liquid lead at one of the conditions. To evaluate the erosion-corrosion attack a new test facility allowing velocities of the lead of up to 20 m/s was designed and constructed. With a CFD-code the behaviour and flow velocity of the lead are simulated.

研究了7A09铝合金二级时效过程中固溶和二级时效条件对其组织和性能的影响。结果表明,第一级110℃时效7 h可对第二级190℃时效起预形核作用,但继续延长第一级时效时间对第二级时效后合金的硬度影响不大;第二级170℃9 h时效具有提高合金硬度的作用;经合适的二级时效处理,7A09铝合金获得的硬度比T6状态的高,为7A09铝合金时效热处理工艺参数的确定及优化提供参考依据。

BEHAVIOR OF FINE V-Ti COMPLEX CARBONITRIDE IN STEEL 09MnVTiN DURING REHEATING

An investigation was carried out of the morphology and microstructure of V-Ti complexcarbonitride in steel 09MnVTiN during reheating under analytical electron microscope.Theprior V-rich ellipsoid V-Ti complex carbonitride particles are replaced progressively byTi-rich cubic ones as the reheating temperature elevated from 1050 to 1400℃.The Ti con-tents in the core and border of particles increase from 15 and 6% in hot-rolled specimens into84 and94% at 1400℃ respectively.     

The conductance and magnetoresistance effect in a periodically magnetically modulated nanostructure

In this paper, we theoretically investigate the conductance and the magnetoresistance effect in a periodically magnetically modulated two-dimensional electron gas. It is shown that there exists a significant conductance difference for electrons through the parallel and antiparallel magnetization configurations, which leads to a considerable magnetoresistance effect. It is also shown that the conductance and the magnetoresistance effect depend on both the temperature and the number of the periodic magnetic barriers.
