At the same time,a tension stress is applied on theγ′phase interfaces along the direction parallel to the stress axis,which results in the lattice expansion ofγ′phase to trap the Al,Ta atoms with the bigger radius.This brings out the accumulation of the solute atoms to form the N-type rafted structure.Al,Ta atoms with bigger radius diffuse to the {100} plane to form the linked bond of the heterogeneous atoms and the stable stacking mode,this is a main reason of promoting the transformation ofγ′phase into the N-type rafted structure.And the change of the strain energy density in different interfaces of the cubical-likeγ′phase is thought to be the driving force of the elements diffusion and theγ′phase directional growth during creep.

拉伸蠕变期间，类立方γ\'相中与施加应力轴垂直的界面受水平切应力，使晶格收缩可排斥较大半径的Al、Ta原子；与应力轴平行的界面受拉伸张应力，使晶格扩张可诱捕较大半径的Al、Ta原子，由此引起的原子偏聚形成γ\'相是自由能降低的过程；其中，较大半径的Al、Ta原子扩散迁移至{100}晶面，形成异类原子结合键及稳定的堆垛方式，是促使γ\'相形成N-型筏状结构的主要原因；而γ\'相不同界面的应变能密度变化是元素扩散及γ\'相定向粗化的驱动力。

By employing the Jordan-Wigner transformation and a modified mean field method, we are able to determine its ground-state quantum phase diagram approximately. The chapter IV is the main part of this Thesis. It contains the main innovations in our work. We propose and study in detail a S=1 Ising chain with the interplay of single-ion anisotropy and dimerization. The main results and innovations are the following: We show that the total number of the zero-component of spins at each site is a conserved quantity. This quantity, which may intuitively called as hole's quantum number, is hidden in the system. We show further that the hole's number in the ground-state is zero; By using the Jordan-Wigner transformation, we map this model onto a series of subsystems described by the spin 1/2 dimerized transverse Ising model. We solve the subsystems exactly, by presenting the exact wave functions and spectra;We show that this system exhibits a series of quantum phase transitions by varying the dimerization strength. We determine the quantum critical points exactly. We also show that the criticality is the same as that of the uniform S = 1/2 transverse Ising chain.
