1A projection method and Kronecker product preconditioner for solving Sylvester tensor equations显示文摘The preconditioned iterative solvers for solving Sylvester tensor equations are considered in this paper.By fully exploiting the structure of the tensor equation,we propose a projection method based on the tensor format,which needs less flops and storage than the standard projection method.The structure of the coefficient matrices of the tensor equation is used to design the nearest Kronecker product(NKP) preconditioner,which is easy to construct and is able to accelerate the convergence of the iterative solver.Numerical experiments are presented to show good performance of the approaches.CHEN Zhen LU LinZhang 2012Science China Mathematics2012,55,6:5
2Effect of Y_2O_3-MgO Addition on Heterogeneous Precipitation-Thermal Reduction Synthesis and Sintering of FeeMo/Si_3N_4 Powders显示文摘Effect of Y2O3e-MgO addition on heterogeneous precipitation-thermal reduction synthesis and the sintering of Fee Mo/Si3N4 powders has been investigated. It was found that the whiskers-like b-Si3N4, good wettability phases on Si3N4 surface, and high toughness Fe phase appeared in Fee Mo/Si3N4 cermets with Y2O3-MgO additives. The results show that Y2O3-MgO additives can effectively optimize the microstructures of Fee Mo/Si3N4 cermets, and improve the material mechanical properties. Therefore, it indicated that Y2O3-MgO additives can be used for strengthening of sintered cermets, and the dual function of whiskers self-toughening and different metal-composition toughening can be achieved in Fee Mo/Si3N4 cermets with Y2O3-MgO additives.Ruiming Yin Fubao Ji Qinglin Hou Fusheng Liu Jing Li Linzhang Chen 2014Journal of Materials Science & Technology2014,30,3:2
