• The amount of nb3si / nb5si3 increases , their morphology tends to be more regular , their distribution becomes more homogeneously with the increasing of withdrawing rate . the microstructure is better oriented along the longitudinal axis of the samples when the withdrawing rate is between 0 . 6 and 6 . 0mm / min . at the same withdrawing rate , the microstructure changes from the beginning part to the ending part of the samples
  铌?硅基rmics材料原始铸态组织由初生nb基固溶体和在其间分布的nb基固溶体+硅化铌共晶团组成；随着抽拉速率的增大，定向凝固共晶组织中硅化铌强化相细化、数量增多、分布趋于规则和均匀，定向效果显著；在相同抽拉速率条件下，区熔试样的组织从起始段到终止段发生了改变。
• The cracks extend along the matrix / strengthening - phases interfaces and form the cleavage steps and tear ridges . there appear some very small dimples on the fracture surfaces of the directionally solidified samples , which come from the nb - based solid solution particles in the big plates of the strengthening phases , but no dimples on the fracture surfaces of the as - cast sample . it can be concluded from above results that niobium - niobium silicide based in - situ composites ( rmics ) with a uniformly orientated microstructure can be produced by the ebfzm with high temperature gradient , and their mechanical properties can be increased
  随着抽拉速率的提高和硅化铌强化相间距与尺度的减小，材料的室温拉伸强度和断裂韧性均有提高， _ b最高可达778 . 4mpa ， k _ ( ic )达到了46 . 3mpa ? m ~ ( 1 / 2 ) ；试样的拉伸断口基本表现为脆性解理断裂的花样，裂纹沿基体强化相界面绕过强化相进行扩展，在裂纹扩展方向存在解理台阶，并形成撕裂棱。
