| 摘 要： | 借鉴“塑性相成型的原理”,在纯碳化硅材料中加入不同质量百分比的金属硅粉、铝粉,研究了硅、铝粉加入后对纯碳化硅材料的成型性能以及烧后试样的体积密度、显气孔率、常温抗折强度的影响。结果表明:在纯碳化硅材料中分别加入硅、铝粉之后,由于金属的延展性,在成型过程中有利的填充了碳化硅颗粒间的空隙,使得干坯更加致密。在烧结过程中,少量的金属颗粒起到烧结助剂的作用,在高温烧结过程中形成液相,充填在关键的碳化硅间隙,使其通过液相烧结成致密体。 |
| 关 键 词： | 碳化硅 金属微粉 力学性能 液相烧结 |

| Abstract: | By means of plastic phase molding,the effect of metal powder(silicon,aluminum) on pressing properties of dried specimens and apparent porosity,bulk density,normal temperature flexure strength of sintered specimens are studied through adding different metal(mass ratio) silicon and aluminum powder to silicon carbon.The results show that: the specimens with metal silicon or aluminum powder become denser because the plastic metal powder contributes to filling the space.Metal powder melt during high temperature,and filling the key space,so specimens become more compact through liquid sinter. |
| Keywords: | Silicon carbon Metal powder Mechanical property Liquid sinter |
