Effect of ZrB Content on the Properties of Copper Matrix Composite.

This study examined the physical, mechanical, tribological, and corrosion properties of copper metal matrix composites reinforced with zirconium diboride (ZrB). Cu-xZrB composites (x = 0.5, 10, 15, 20 wt.

Processing and Properties of ZrB-Copper Matrix Composites Produced by Ball Milling and Spark Plasma Sintering.

Copper matrix composites with zirconium diboride (ZrB) were synthesised by ball milling and consolidated by Spark Plasma Sintering (SPS). Characterisations of the ball-milled composite powders were performed by scanning electron microscopy (SEM), X-ray diffraction, and measurement of the particle size distribution. The effect of the sintering temperature (1123 K, 1173 K, and 1223 K) and pressure (20 MPa and 35 MPa) on the density, porosity, and Young's modulus was investigated.

Corrosion Resistance of Nickel-Aluminum Sinters Produced by High-Pressure HPHT/SPS Method.

As part of extensive research on the properties of nickel-aluminum alloys, corrosion tests of sintered materials produced by the innovative HPHT/SPS (high pressure, high temperature/spark plasma sintering) method were performed in 0.1 molar HSO acid. The hybrid, unique device used for this purpose (one of only two such devices operating in the world) is equipped with a Bridgman chamber, which allows heating with high-frequency pulsed current and sintering of powders under high pressure in the range of 4-8 GPa and at temperatures up to 2400 °C.

Effect of Zirconium Diboride and Titanium Diboride on the Structure and Properties of 316L Steel-Based Composites.

The effect of zirconium diboride (ZrB) and titanium diboride (TiB) on the microstructure as well as the physical, mechanical, and tribological properties of composites based on 316 L steel is presented. Each reinforcing phase was added to the base alloy in the amount of 5 wt% and 10 wt%. The composites were fabricated by the SPS process (Spark Plasma Sintering).

Fabrication of the Zirconium Diboride-Reinforced Composites by a Combination of Planetary Ball Milling, Turbula Mixing and Spark Plasma Sintering.

The aim of this study was to carry out the consolidation of zirconium diboride-reinforced composites using the SPS technique. The effect of the adopted method of powder mixture preparation (mixing in Turbula or milling in a planetary mill) and of the reinforcing phase content and sintering temperature on the microstructure, physical properties, strength and tribological properties of sintered composites was investigated. Experimental data showed that the maximum relative density of 94%-98% was obtained for the composites sintered at 1100 °C.

Microstructure and Properties of TiB Composites Produced by Spark Plasma Sintering with the Addition of TiSi.

Titanium diboride (TiB) is a hard, refractory material, attractive for a number of applications, including wear-resistant machine parts and tools, but it is difficult to densify. The spark plasma sintering (SPS) method allows producing TiB-based composites of high density with different sintering aids, among them titanium silicides. In this paper, TiSi is used as a sintering aid for the sintering of TiB/10 wt % TiSi and TiB/20 wt % TiSi composites at 1600 °C and 1700 °C for 10 min.

Effect of Reactive SPS on the Microstructure and Properties of a Dual-Phase Ni-Al Intermetallic Compound and Ni-Al-TiB Composite.

As part of the tests, a two-phase NiAl/NiAl alloy and a composite based on this alloy with 4 vol% addition of TiB were produced by the reactive FAST/SPS (Field Assisted Sintering Technology/Spark Plasma Sintering) sintering method. The sintering process was carried out at 1273 K for 30 s under an argon atmosphere. The effect of reactive SPS on the density, microstructure, and mechanical and tribological properties of a dual-phase Ni-Al intermetallic compound and Ni-Al-TiB composite was investigated.

Influence of ZrB on Microstructure and Properties of Steel Matrix Composites Prepared by Spark Plasma Sintering.

In this study, four composites with different ZrB content were made by the Spark Plasma Sintering (SPS/FAST) technique. The sintering process was carried out at 1373 K for 5 min under an argon atmosphere. The effect of ZrB reinforcing phase content on the density, microstructure, and mechanical and tribological properties of composites was investigated.
