Microstructure and Performance of Fused Silica-based Ceramic Core Reinforced by Mullite Fiber Xin Lia, Jiansheng Yaob, Xiaoguang Liuc, Hongna Fand and Shuxin Niue Science and Technology on Advance High Temperature Structural Materials Laboratory, Beijing Institute of Aeronautical Materials, Beijing 100095, China alxin_86@163.com, btju_yjs@163.com, cxiaogliu@sina.com, dfanhn0404@126.com, eanndy001@163.com Keywords: Silica-based ceramic cores, Mullite fiber, Investment castings, Shrinkage.
The results showed that in the premise of maintaining strength of materials, mullite fiber could decrease significantly the shrinkage.
In this study, low content of short-cut mullite fibers are added into fused silica-based ceramic core materials.
Characteristics of the used fused silica, mullite powder and mullite fibers as raw materials, were illustrated in Table 1.

Fig.2 The FEM model of simplified equivalent beam Establishment of quivalent mechanical models for different loads If the beam was composed of two materials and the cross-section of the beam is shown in Fig.3, the beam can be looked as a uniform equivalent beam composed of a material so as to establish its equivalent mechanical model based on material mechanics and composite material mechanics for different loads.
In Fig.3, the material of Ⅰfield is steel, the material of Ⅱfield is alumimum.

On the other hand, oxide materials are the materials which have organic strength and current constancy from top to bottom.
The materials used were of varying sizes and are not homogeneous.
Since the unscattered beam is selected, region with high mass materials seems to be dark.

Introduction With the development of science and technology, the harder, stronger and tougher materials are frequently used.
The new engineering materials with improved thermal, chemical and mechanical characteristics make it impossible to machine by the conventional machining processes of cutting and abrasion.
The applications of SEAM mostly solve the difficult processing problems in pertinence and economic efficiency way for the new special conducting materials such as cermets, titanium alloy, molybdenum alloy, stainless steel, rare earth alloy, tungsten carbide, high chrome alloy, high manganese alloy and high nickel alloy etc.
The materials with ultrahard, superstrength, high tenacity, high red-hardness, high-wearing feature and severe cold hardening are used for new product.
