Rapid Sintering

Spark plasma sintering (SPS), as a developed rapid sintering technique, has a great potential for producing larger metallic glassy alloy specimens in a variety of shapes than those fabricated by casting methods, and can readily produce composites by dispersing crystalline particles in the glassy matrix. In this study, the Ni52.5Nb10Zr15Ti15Pt7.5 bulk metallic glassy matrix composites dispersed homogeneously with ceramics ZrO2 particulates were fabricated by the SPS process. The plastic ductility of the Ni52.5Nb10Zr15Ti15Pt7.5 glassy matrix composites was improved by adding ZrO2 particulates into the glassy alloy. The matrix of the fabricated composites maintained a glassy phase after the SPS process.

The influence of direct current pulse on–off patterns on spark plasma sintering of [Fe0.8Co0.2B0.05Si0.2]96Nb4 on kinetics competition and coordination mechanism of the interface bonding and crystallization has been investigated systematically. No crystallization of metallic glassy matrix and good bonding state between the particles were responsible for good mechanical properties of the fabricated Fe-based bulk glassy alloy at 2:9 (on: off) pattern. The higher local micro area’s instantaneous power and larger cooling time caused by low pulse duty ratio played a vital role in consolidation of amorphous alloy powder and desired structural properties.

Ceramic matrix composites (CMCs) based on silicon carbide (SiC) are promising materials for applications as structural components used under high irradiation flux and high temperature conditions. The addition of SiC fibers (SiCf) may improve both the physical and mechanical properties of CMCs and lead to an increase in their tolerance to failure. This work describes the fabrication and characterization of novel preceramic paper-derived SiCf/SiCp composites fabricated by spark plasma sintering (SPS). The sintering temperature and pressure were 2100 °C and 20–60 MPa, respectively. The content of fibers in the composites was approx. 10 wt.%. The matrix densification and fiber distribution were examined by X-ray computed tomography and scanning electron microscopy. Short processing time avoided the destruction of SiC fibers during SPS. The flexural strength of the fabricated SiCf/SiCp composites at room temperature varies between 300 and 430 MPa depending on the processing parameters and microstructure of the fabricated composites. A quasi-ductile fracture behavior of the fabricated composites was observed.

Metal matrix nanocomposites (MMNCs) are those metal matrix composites where the reinforcement is of nanometer dimensions, typically less than 100 nm in size. Also, it is possible to have both the matrix and reinforcement phases of nanometer dimensions. The improvement in mechanical properties of MMNCs is attributed to the size and strength of the reinforcement as well as to the fine grain size of the matrix. Spark plasma sintering has been used extensively over the past years to consolidate wide range of materials including nanocomposites and was shown to be effective noneconventional sintering method for obtaining fully dense materials with preserved nanostructure features. The objective of this work is to briefly present the spark plasma sintering process and review published work on spark-plasma-sintered metals and metal matrix nanocomposites.
