At present, most of the commonly used anode materials are porous Ni-A1 and Ni-Cr alloys. because of the high cost of Ni, the researchers are looking for a suitable alternative material.
Therefore, Ni can be replaced by Cu as the anode for preparing the MCFC, but Cu can be more quickly in corrosion and weight loss at a high temperature (650℃) and in (Li, K) environment, Studies have shown that Cu-35% Ni anode have similar electrochemical properties to pure Ni anode, and Cu-35% Ni anode can improve high temperature performance of materials after the addition of A1element, thereby improving creep resistance of the anode materials.
The addition of Al element can enhance the creep resistance sinter-ability of anode materials.
Since MCFC is stacked by a plurality of cells, and wrapped by the outer seal parts, the anode materials are subject to the pressure load under the working conditions, it’s very important to study the compression performance of the anode materials. especially there’s no report on the study of creep properties of porous copper alloy about the Cu alloy.

In recent years, many attempts to obtain superior quality by ductile regime machining of brittle materials were made [2-4], but the mechanism of brittle-ductile transition of hard brittle materials still lacks of in-depth study.
Indentation test is a method to find the critical condition of brittle-ductile transition of hard brittle materials.
So the mechanism of brittle-ductile transition of hard brittle materials at different temperatures is of critical importance to ultra-precision machining.

FEM using Lagrangian approach for rigid-plastic materials is popular in simulating metal forming processes[1-3].
The flow of material is uniform and the front edge of the material is regular, only material in boundary flows a little slowly because of effect of friction.
