Pure Niobium is a material of interest for high-energy-physics applications including superconducting accelerators. Cold-rolled sheets Nb exhibit significant plastic anisotropy. Here we report on the mechanical and forming properties 99.95% pure, 1.02 mm thin, cold-rolled sheet. Uniaxial tension, biaxial tension disc compression experiments are performed, first two at multiple angles to rolling...
In recent years, hydroforming process has been applied in different industries such as aerospace, automotive and military industries due to its advantages, such as high dimensional accuracy, capability of forming complicated parts and high drawing ratio. Hydrodynamic deep drawing with radial pressure is one type of hydroforming process. In this paper, forming of cylindrical cups in hydrodynamic...
| H igh sea surface temperature (SST) is generally required for deep convection that reaches the tropopause. In the current climate, the SST threshold for deep convection is somewhere around 26°–27°C, depending upon region and season (Gra-ham and Barnett 1987; Waliser et al. 1993). Over such warm oceans, SST changes cause deep convective adjustment , which in turn excites the dynamic response o...
