The effects of wheel speed, Zr content, post-ball milling process and heat treatment on the structure, anisotropy, magnetic properties and phase transition of the melt-spun SmCo 7−x Zr x alloys were investigated. The crystallographic c-axis is parallel to the ribbon plane for the ribbons prepared at low speeds of 5 and 15m/s, and this orientation is reduced at higher speeds. The out-of-plane...
We propose an atomic simulation techniques to understand the chemical-mechanical relationship of amorphous/porous silica based low-dielectric (low-k) material (SiOC(H)). The mechanical stiffness of the low- k material is a critical issue for the reliability performance of the IC backend structures. Due to the amorphous nature of the low-k material which has till now unknown molecular structure, a...
For the thermomechanical analysis of multilayer substrates, detailed FE is not feasible. To capture all features, the number of elements necessary would lead to extreme computational loads. To overcome this, an elementwise homogenization method utilizing multiple representative volume elements is presented. Employing a global-local step it is still possible to obtain accurate values for local quantities...
