Production of highly porous composite materials by traditional materials processing is limited by difficult processing techniques. This work investigates the use of self propagating high temperature (combustion) synthesis (SHS) to create porous tricalcium phosphate (Ca3(PO4)2), TiB-Ti, and NiTi in low and microgravity. Combustion synthesis provides the ability to use set processing parameters t...

Aluminum matrix composites reinforced with ultra-fine refractory titanium carbide feature a unique combination of properties. They are promising structural materials. Self-propagating high-temperature synthesis (SHS) is an affordable and energy-saving composite making process. It involves the exothermic reaction between carbon (or their compounds) directly in melt. We studied properties SHS bas...

Al-Ti-B master alloys are widely used in the aluminum industry as grain refiners for the control of the microstructure of the aluminum alloys. The SHS (self-propagating high-temperature synthesis) is an ex situ method that uses exothermic reactions to sustain the chemical reaction in a combustion wave. The advantages of SHS are the low energy requirement, simplicity and product purity. However,...

Abstract In the first part of paper, effect mechanical treatment particles reacting Ti + C Me (Me = NiCr or Co) mixtures on process self-propagating high-temperature synthesis (SHS) is investigated. It shown that as a result SH-synthesis in free burning mode, metal-ceramic sinter high porosity formed, which easily destroyed by action. An increase volume fraction metal binder (NiCr leads to redi...

The fabrication by Spark Plasma Sintering (SPS) of bulk high entropy ceramics from powders obtained Self-propagating High temperature Synthesis (SHS) is addressed in this work. effect produced the introduction 1 wt.% graphite to before SPS investigated under different conditions. final density and composition sintered (Hf0.2Mo0.2Zr0.2Ti0.2Ta0.2)B2 (Hf0.2Mo0.2Zr0.2Ti0.2Nb0.2)B2 are found be nega...
