The article reflects the results of many years’ (since 1972) research of structural, hydrodynamic, thermophysical and mechanical properties of metal felt capillary structures (MFCS) of heat pipes (HP). These structures were made from the discrete copper, stainless steel, or nickel sintered fibres of 0.002 to 0.01-m length and diameter within 20 to 70 μm. They were intended for the HP with shell...

We propose a simple and low-cost process for the preparation of porous Ti foams through a sponge replication method using single-step air sintering at various temperatures. In this study, the apatite-forming ability of air-sintered Ti samples after 21 days of immersion in simulated body fluid (SBF) was investigated. The microstructures of the prepared Ca-P deposits were examined by X-ray diffra...

Studies have been conducted to find Materials with microstructures which Minimize the formation of blisters. A promising class of materials appears to be sintered metal powder with small average grain sizes and low atomic number Z. Studies of the surface erosion of sintered aluminum powder (SAP 895) and of aluminum held at AOO'C due to blistering by 100 keV helium ions have been conducted and t...

In this work, austenitic oxide dispersion strengthened (AODS) steel of composition Fe–16Cr–16Ni–1.5 W–0.21Ti–0.3Y2O3 (wt. %) was fabricated using two–stage ball milling followed by consolidation through spark plasma sintering (SPS). the first–stage, mechanical alloying (MA) ferritic powder and nano sized Y2O3 carried out. This addition Ni in second–stage milling. SPS milled out at 900, 950, 100...
