Sažetak
The paper presents the first extensive research on microstructural and mechanical properties of a novel porous copper structure with unidirectional longitudinal pores (UniPore) structure. The unique fabrication method is based on explosive compaction of copper pipes. The high pressure achieved by explosive detonation during compaction causes explosive welding between the pipe surfaces resulting in a regular and homogeneous cellular cross-section. The quality of bonding surfaces has been studied on transversal and longitudinal cross-sections by a metallographic analysis. The mechanical properties of three different UniPore structure porosities (between 0.32 and 0.58) have been evaluated. The anisotropy of the UniPore structure has been analysed by compressive quasi- static test loading in transversal and longitudinal direction regarding to the pore orientation. The three-point bending tests have been performed at quasi-static and dynamic loading conditions supported by infrared thermography for visualising the propagation of plastic regions and crack on the specimen's surface. It has been confirmed that the fabricated UniPore specimens exhibit a very low deviation of geometrical properties. Additionally, excellent compressive properties (for both loading directions) with high energy absorption capability have been observed. The three-point bending tests have demonstrated advantageous ductile failure of UniPore specimens that is more postponed at dynamic loading.
