MS界面稳定性判据新探 刘林1,杨爱民1 (1.西北工业大学;2.西安石油学院) 摘要:给出了定向凝固平界面稳定性新的判据,(1+3k/y0)ξ+[1+(1+k)y0/4k≥1其中A为无量纲速度,ξ GLS/mGc,yo是有关A和ξ的一个二次方程的根.新判据的最大特点是可直接由凝固参数推断界面的稳定性,不用解高次方程发现MS绝对稳定性速度Va仅在加权温度梯度GLS→0时才是界面稳定性的临界速度当GLS＞0时,K大于实际的临界速度.给出了一个新的绝对稳定性梯度条件,并求出了最小的绝对稳定性无量纲临界梯度. 关键词:界面稳定性; 绝对稳定性; 临界速度; 定向凝固; 温度梯度; [全文内容正在添加中] ......
CoO掺杂对15(20Ni-Cu)/(NiO-NiFe2O4)金属陶瓷导电性能的影响吴海明,李志友,甘雪萍,周科朝中南大学粉末冶金国家重点实验室摘 要:在15(20Ni-Cu)/(NiO-NiFe2O4)金属陶瓷中掺杂CoO,制备15(20Ni-Cu)/[10(xCoO-yNiO)-90NiFe2O4]金属陶瓷,研究CoO掺杂量x对15(20Ni-Cu)/(NiO-NiFe2O4)金属陶瓷材料的烧结致密化,物相组成以及电导率的影响.结果表明:当CoO掺杂量x为0~10%时,烧结样品中主要含有NiO,NiFe2O4,CuNi固溶体三相,Co2+离子嵌入到NiO-NiFe2O4陶瓷基体中取代部分Ni2+,形成NixCo1?xFe2O4和NiyCo1?yO相.CoO掺杂能提高该金属陶瓷的烧结致密度和电导率......
