Interaction between Fe66Cr10Nb5B19 metallic glass and aluminum during spark plasma sintering

Effect of Spark Plasma Sintering in Fabricating Carbon Nanotube Reinforced Aluminum Matrix Composite Materials

Carbon nanotubes (CNT) are attractive next generation materials due to their unique properties, which lead to high mechanical, electrical, and thermal performance (Iijima, 1991; Endo et al., 1976; Niyogi et al., 2002; Komarov & Mirnov, 2004). This unique nano order material can not only be utilized on its own in precision industrial fields but can also provide high performance functionality in ...

Spark Plasma Sintering As a Solid-State Recycling Technique: The Case of Aluminum Alloy Scrap Consolidation

Recently, "meltless" recycling techniques have been presented for the light metals category, targeting both energy and material savings by bypassing the final recycling step of remelting. In this context, the use of spark plasma sintering (SPS) is proposed in this paper as a novel solid-state recycling technique. The objective is two-fold: (I) to prove the technical feasibility of this approach...

Spark Plasma Sintering: A Useful Technique to Develop Large-Sized Bulk Metallic Glasses

Metallic glasses exhibit unique combination of physical, chemical and mechanical properties due to their amorphous nature which lacks long range order and defects such as grain boundaries and dislocations [1,2]. In the past two decades, they have been rapidly developed for application in many fields. However, the disadvantages such as poor plasticity and limited dimensions hamper their large-sc...

Spark Plasma Sintering of Negative Temperature Coefficient Thermistor Ceramics

Densification and polymorphic transition of multiphase Y2O3 nanoparticles during spark plasma sintering

Multiphase (MP) monoclinic and cubic Y2O3 nanoparticles, 40 nm in diameter, were densified by spark plasma sintering for 5–15 min and100 MPa at 1000 C, 1100 C, and 1500 C. Densification started with pressure increase at room temperature. Densification stagnated during heating compared to the high shrinkage rate in cubic single-phase reference nanopowder. The limited densification of the MP nano...
