Effect of plasma sintering process on the mechanical properties of WC/Cr3C2/La2O3 cutting tool materials

Fenmo yejin jishu
To solve the problem of adhesive phase wear for the traditional cemented carbide tools in the high-speed cutting process, the WC/Cr3C2/La2O3 tool materials were prepared by spark plasma sintering (SPS). The effects of Cr3C2 addition amount (mass fraction,

Synthesis, Sintering, and Electrical Properties of BaCe0.9−xZrxY0.1O3−δ [PDF]

, 2008
BaCe0.9−xZrxY0.1O3−δ powders were synthesized by a solid-state reaction. Different contents of cerium and zirconium were studied. Pellets were sintered using either conventional sintering in air at 1700◦C or the Spark Plasma Sintering (SPS) technique ...

Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

Advanced Engineering Materials, EarlyView.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

Effect of Sintering Temperature on the Thermoelectric Properties of Ag2Se Fabricated by Spark Plasma Sintering with High Compression

Advanced Energy & Sustainability Research, 2023
Silver selenide (Ag2Se) is a high‐performance thermoelectric (TE) material near room temperature. This research improves its TE figure‐of‐merit (ZT) by varying the sintering temperatures (423–723 K) in the spark plasma sintering (SPS) process with high ...

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

, 2011
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

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics

Advanced Engineering Materials, EarlyView.
Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

High-pressure, high-temperature plastic deformation of sintered diamonds [PDF]

Diamond and Related Materials, 2015
Abstract The strength of polycrystalline diamond (PCD) was investigated through a high pressure (P) and temperature (T) deformation experiment. Prior to the deformation experiment, two bulk samples were sintered back to back under identical conditions with two different precursors, which shared identical initial grain size distribution.

Influence of an Oxygen‐Free Atmosphere on Diamond‐Single‐Grain Scratching of Ti–6Al–4V

Advanced Engineering Materials, EarlyView.
Single‐grain scratching of Ti–6Al–4V is investigated under controlled, oxygen‐free, and ambient atmospheres using a novel experimental setup with in situ high‐speed imaging. The approach enables direct observation of chip formation and adhesion under suppressed oxidation.

Low-Temperature Rapid Synthesis and Superconductivity of Fe-Based Oxypnictide Superconductors

, 2010
we were able to develop a novel method to synthesize Fe-based oxypnictide superconductors. By using LnAs and FeO as the starting materials and a ball-milling process prior to solid-state sintering, Tc as high as 50.7 K was obtained with the sample of Sm ...

High Pressure Sintering of Nano-polycrystalline Thermoelectric Materials

The Review of High Pressure Science and Technology, 2005
In this article we describe the possibility of the improvement of thermoelectric properties of polycrystalline materials through means of high pressure sintering. We made an attempt to reduce the thermal conductivity, which is one of the important parameter of thermoelectric properties, by the high pressure sintering of nano-crystalline particles.
