Bulk Ni-W alloys having composite-like microstructures are processed by spark plasma sintering (SPS) route of Ni and W powder blends as reported in a recent study of Sadat et al. (2016) (DOI of original article: doi:10.1016/j.matdes.2015.10.083) [1]. The present dataset deals with determination of mass density and evaluation of room temperature compressive mechanical properties as function of t...

A spark plasma sintering (SPS) apparatus was used for the first time as an analytical testing tool for studying creep in ceramics at elevated temperatures. Compression creep experiments on a fine-grained (250 nm) polycrystalline magnesium aluminate spinel were successfully performed in the 1100-1200 °C temperature range, under an applied stress of 120-200 MPa. It was found that the stress expon...

TiC-Ti-Al mixed powders and TC4 titanium alloy foils were overlapped layer-by-layer in the graphite die. The TC4-based laminated composite sheets reinforced by Ti aluminide and carbide were successfully fabricated via spark plasma sintering (SPS) at 1100 °C with a well-bonded interface. The composite layers were mainly composed of TiAl, Ti₃Al, Ti₂AlC, and Ti₃AlC₂ phases. The carbides particles ...

To satisfy the essential needs, including energy requirements, for human and robotic space explorations on planetary objects like Moon, Mars asteroids, proper exploitation of resources available in-situ represents a crucial issue. Along this line, present work investigates potential sintered lunar regolith simulant (JSC-1A) possible solar harvesting thermal storage applications. Regolith powder...

In order to clarify plastic deformation behavior and mechanism of fracture energy absorption Ti3SiC2, Vickers indentation tests were conducted for Ti3SiC2 sintered bodies with various textured orientations. Textured fabricated by slip casting in a strong magnetic field spark plasma sintering (SPS), their orientation distribution analyzed SEM/EBSD. It was found that the around indents such as an...

High-performance complex gear cutters and high-temperature bearings are just some of the applications where high-speed steels (HSSs) shine as a preferred material choice owing to their high hardness outstanding wear resistance. In this work, effects sintering temperature on microstructure mechanical properties S390 HSS prepared via spark plasma (SPS) were investigated with range temperatures fr...

The quaternary sulphide V-Sn colusite, Cu26V2Sn6S32, is one of the most promising cost-efficient thermoelectric materials to date because low toxicity, wide availability and cost composing elements. Recent studies have demonstrated potential this environmentally-friendly material its transport properties are now well understood. In present work, we take next step producing large quantities opti...

Large-scale Cu2S tetradecahedrons microcrystals and sheet-like Cu2S nanocrystals were synthesized by employing a hydrothermal synthesis (HS) method and wet chemistry method (WCM), respectively. The morphology of α-Cu2S powders prepared by the HS method is a tetradecahedron with the size of 1–7 μm. The morphology of β-Cu2S is a hexagonal sheet-like structure with a thickness of 5–20 nm. The resu...

Yb doped (0, 0.02, 0.1 and 0.5 at%) MgO transparent ceramics were synthesized through spark plasma sintering (SPS) at the relatively low temperature of 1100 °C for 5–60 min under a pressure 105 MPa. The effects dopant concentration holding time on densification microstructure evolution investigated. All reached relative density greater than 99.20%. 0.02% Yb-doped ceramic sintered 60 showed high...

ZrW 2 O 8 is known as a negative coefficient of thermal expansion (CTE) material. In contrast, the studies other properties than CTE , such conductivity and mechanical properties, are limited. Herein, highly dense bulk sample (%T.D. > 95%) from very fine powder (D50 0.3 μm) with crystalline size 31 nm using spark plasma sintering (SPS) technique synthesized. It revealed that exhibits lowest ...
