In order to investigate the effects of temperature on the contact strengths of the thick-walled cellular solids, materials of H59 brass was chosen for the preparation of cylindrical specimens which contain single pore, double pores, three pores and four pores respectively. The contact strengths of these specimens were determined in a YE-600 hydraulic testing machine at 20°C (room temperature) and 300°C respectively. The experimental results show that: the temperature had great effect on contact strength of the thick-walled cellular solids, mainly reflected in loading capacity and deformation, when the temperature increased from 20°C to 300°C, the loading capacity of the solids were reduced by 10.94 to 14.85% and the corresponding deformations were increased by 97.50 to 108.33%, which depended on the micro-pores structures. Furthermore, the effects of temperature on cracks out-look mainly reflected in cracks deepening with temperature. When the temperature increased from 20°C to 300°C, the depth of the cracks increased about 78 to 110%, which also depended on the micro-pores structures. However, temperature had little effect on the initiating position of the cracks for all micro-pores structures discussed from 20°C to 300°C.
