在垂直方向的静态磁场和水平方向的直流电或者交流电的同时作用下进行了碳素钢凝固。电磁力作用于钢,从而会影响凝固过程的组织形态。切割和侵蚀在不同电磁力作用下凝固的试样,以观察宏观和微观的组织形貌。没有电磁力作用下形成的凝固组织是枝晶晶粒结构。相反,在0.3T静态磁场和20A直流电的共同作用条件下形成球状晶结构。在0.3T静态磁场和80A、2kHz交流电的共同作用条件下凝固组织只是有一部分是球状晶结构。因此,从电流强度的角度来看,改善凝固组织由枝晶晶粒到球状晶粒结构的转变,静态电磁场和直流电的共同作用更好于静态电磁场和交流电的共同作用。

The effect of pore water chemistry on anisotropic behavior of consolidation and shear strength of reconstituted Ariake clay has been investigated *** types of chemicals added into the pore water of the soil for enhancing flocculation microstructure of soil particles are sodium chloride(salt)(NaCl),and calcium chloride(CaCl_(2));and two dispersants added are sodium triphosphate(Na_(5)-P_(3)O_(10))and sodium hexametaphosphate(Na_(6)P_(6)O_(18)),*** concentrations of these chemicals in pore water were 2-3%.Degrees of anisotropy of the coefficient of consolidation and undrained shear strength decreased with adding NaCl and CaCl_(2),but increased with adding the *** of anisotropy also increased with one-dimensional(1D)deformation and the samples with dispersive additives had higher increase *** has been confirmed qualitatively by scanning electron microscopy(SEM)images that adding dispersive chemicals promoted the formation of dispersive microstructure and increased the degree of anisotropy,and the chemicals enhancing flocculent microstructure had an inverse *** possible application of the findings to underground construction has been discussed also.
