Mechanical Properties of High Dense Coal Fly-Ash Bulk Materials by Plasma Spark Sintering (SPS)

Production geopolymer materials by coal fly ash

Coal ash is the main waste from power plant. It is estimated that the consumption of the coal for power plant will increase to 240 million tons each year and the coal ash wastes will produce more than 2 million tons per year. Although the utilization of coal fly ash can be reached 74.1%, large amount of coal fly ash and bottom ash still cannot be utilized. The purpose of this research is to dev...

Fabrication of Nanostructured Cu matrix Nanocomposites by High Energy Mechanical Milling and Spark Plasma Sintering

Spark plasma sintering (SPS) is a sintering process that is capable of sintering hard worked powders in short times. This technique was used to fabricate bulk Cu and Cu-SiC nanocomposites. Pure Cu and mixed powders of Cu including 4 vol% of SiC nanoparticles were mechanically alloyed for 25 h and sintered at 750˚C under vacuum condition by SPS method. Microstructures of the materials were chara...

Effect of Nano-TiN on Mechanical Behavior of Si3N4 Based Nanocomposites by Spark Plasma Sintering (SPS)

Nanostructured Al-ZrAl3 materials consolidated via spark plasma sintering: Evaluation of their mechanical properties

Aluminium based nanostructured materials with additions of 0.5, 1 and 1.5 weight% of zirconium have been produced and sintered using the spark plasma sintering technique in order to promote the nucleation of ZrAl3 platelets. The mechanical behaviour of all these nanocomposites was determined by means of the Small Punch Test. Zirconium additions significantly decrease the mechanical properties o...

Spark Plasma Synthesis (SPS) Device for Sintering of Nanomaterials

It is known that work pieces with nanocrystalline structure condition have much higher performance than those with an ordinary structure. There are known number of techniques for manufacturing of nanocrystalline materials in powder condition however a question of manufacturing bulk pieces in the same nanocrystalline state mentioned is that compaction and synthesizing of nanocrystalline powders ...
