DOI:REVIEW Field-Assisted Sintering Technology/ Spark Field-assisted sintering technology/Spark plasma sintering is a low voltage, direct current (DC) pulsed current activated, pressure-assisted sintering, and synthesis technique, which has been widely applied for materials processing in the recent years.
Aug 01, 2020 · The sintering process was accomplished using an SPS-20T-10 spark plasma sintering SPS machine (Nanozint 10i, Khala Poushan Felez Co., Iran) at 1900 °C. Besides, an external pressure of 40 MPa was applied over the sintering, and the samples were maintained at the maximum temperature for 7 min.
Fe-based metallic glass particles reinforced Al-7075 Aug 01, 2020 · Main experimental setup. (a) Ball mill, (b) Spark plasma sintering machine, (c) Hot extrusion machine. The phase analysis of the composites was investigated by X-ray diffractometer (XRD, Rigaku D/max) with Cu K radiation ( = 1.5418 Å). The glass transition temperature
Introduction to Liquid Phase Sintering SpringerLinkA common characteristic of ail forms of sintering is a reduction in surface area with concomitant compact strengthening. This occurs through the formation of interparticle bonds brought about by atomic motion at the sintering temperature. During liquid phase sintering a liquid phase coexists with a particulate solid at the sintering temperature.
2.1 Conservation equations In order to analyze the sintering process of an industrial strand machine, a multiphase, multi-component, three-dimensional mathematic al model is proposed. The model considers the phases interacting simultaneously and the ch emical species of each phase is calculated based on the chemical species conservation equations.

Solid Phase Sintering - an overview ScienceDirect TopicsSolid-state sintering can be enhanced or activated by small amounts of additives that segregate to grain boundaries and form a high-diffusivity second phase. The most effective sintering activators for W and other refractory metals are transition metals such as Co, Fe, Ni, Pd, and Pt, which have a high solubility for W and relatively low
The sintering machine is assisted by a uniaxial press, punch electrodes, vacuum chamber, Grain sizes were retained to within 500 nm and 1 m for sintering temperatures of 900°C and 1100°C, respectively. Figure 11 The phase with grain size less than 100 nm is NiTi phase 1×600m2 Sintering Machine Phase-I ProjectTianjin MCC20 Construction achieves 1,100 percent ROI on Bentley toolset deployed on short-cycle construction of Chinas largest Sintering Machine
