“…It is noted that the first sample that does not contain graphite is higher in density than the rest of the samples, and the sintering density has limits of 8.64g/cm 3 . The possible reason for this is the sintering temperature, which reduced the porosity and caused a high-density structure consistent with Yusoff et al (2013), where the measured density value at sinter temperature 950ºC was 8.2g/cm 3 .…”

In this study, copper-3%WC-graphite hybrid compounds were produced by powder metallurgy. The effect of different concentrations of graphite (0, 2%, 4%, 6%, 8%) on sinter density and thermal conductivity of the compounds was studied. The results indicated that the sintering density decreased with increasing graphite concentrations by 16.75%, and the thermal conductivity decreased at a rate of 25.90%. This decrease in thermal conductivity is due to the low thermal conductivity of both WC and graphite.

“…After pressing, sintering was performed at 930° C for two hours. The researchers found (Yusoff et al 2013) that the suitable sintering temperature for copper sintering materials supported by tungsten carbide ranges from 850° C to 950° C for two hours.…”

In this research, 10, 15, 20, and 25 wt.% of WC-TiC-Co particles were coated with a nano-particles layer of copper by the electro-less deposition technique. All the composites were compacted at 900 MPa, and then sintered at 1000 and 1100℃ for 120 min in a hydrogen atmosphere furnace. Nano-composites, which sintered at 1100℃ exhibit relative density higher than those sintered at 1000℃. To investigate the crystal structure and chemical composition of the WC-TiC-Co powders, XRD was used. SEM and EDAX analysis for the sintered samples were performed to investigate the microstructure and morphology of the composites. The relative density, hardness, electrical conductivity and yield stress based on the results of the hardness values were studied. The results revealed that the relative density, hardness, and the yield stress based on the results of the Vickers hardness were improved by increasing the WC-TiC-Co content. On the other hand, the electrical conductivity was decreased by increasing the WC-TiC-Co content.

“…After milling, high temperature sintering activates thermal diffusion of atoms resulting into recombination of nano‐sized crystallites giving rise to bigger crystallites. As crystallites become bigger in size, stress relaxation takes place, consequently decrease in lattice strain is observed after heat treatment …”

The present work reports synthesis and structural and magnetic studies of Ni46Cu4Mn45Sn5 shape memory alloy. The synthesis was done using solid state non‐equilibrium mechanical alloying (MA) technique. MA was performed in a Pulverisette‐6 ball milling machine using Tungsten Carbide (WC) bowl and balls. Ball to powder weight ratio of 10:1 and rotation speed of 300RPM were taken as milling parameters. After 20hr milling, the obtained powder was consolidated and quenched from high temperature to induce martensitic phase transformation. X‐ray diffraction (XRD) study indicates a phase mixture of austenite and martensite phase. Variation in lattice strain and crystallite size with milling time is calculated. Microstructural study reveals dual phase mixture after quenching. Phase transformation study carried out by Differential Scanning Calorimetric (DSC) indicates martensitic phase transformation of reversible nature. Vibrating sample magnetometer (VSM) has been utilized for magnetic characterization.
