Influence of a Liquid on the Deformation Behavior of Porous Nickel and Titanium under Compression

The deformation behavior of capillary porous (CP) Ni and CP Ti is examined under uniaxial compression in air, water, ethanol. metals contained inert liquids such as H20 C2H5OH are used the heat pipes' active elements space applications. samples for mechanical testing were isostatic compacting vacuum annealing (porosity 60%). Uniaxial tests carried out ethanol Shimadzu AG-50K XD (traverse rate 0.1 mm/min). It was shown that exhibit ductile all cases, which inherent to Ti. environment induces increase strength total both materials compared air water. Therefore, a pipe's failure containing matrixes working body caused rather by manufacturing defects, but not structural materials' intrinsic properties.
