“…The microhardness measured for the sample (#CNH) showed an average value of HV ¼ 1085. Literature on microhardness of WC/Co ranges from 900-2100 Vickers 1,[8][9][10][11] depending on the composition and the method adopted.…”

The explosive compaction technique has been applied to consolidate WC/Co powder to make a coating layer on a steel substrate, and the microstructure and some properties are investigated. Explosive compaction was performed using an improved method through underwater shock compression. Two types of assemblies, open and closed types were used for the experiments for generating relatively low and high pressure respectively. The effect of a thin nitrocellulose layer placed above the powders and the effect of the following heat treatment were investigated. In most of the experiments, the WC/Co layer was successfully recovered without cracks. The effects of applying higher underwater shock pressure, role of nitrocellulose as self combustible material and the following heat treatment showed positive effect to improve the properties by the increase of hardness as well as wear resistance of the coating layer.

Nanopowders of MgO, Al 2 O 3 and SiO 2 were made by high energy ball milling. The rapid sintering of nanostructured MgAl 2 O 4 -Mg 2 SiO 4 composites was investigated by the pulsed current activated sintering process. The advantage of this process is that it allows very quick densification to near theoretical density and inhibition of grain growth. Highly dense nanostructured MgAl 2 O 4 -Mg 2 SiO 4 composites were produced with simultaneous application of 80 MPa pressure and pulsed current of 2800 A within 2 min. The sintering behavior, grain size and mechanical properties of MgAl 2 O 4 -Mg 2 SiO 4 composites were investigated.

“…More recently, a new approach has been developed in which synthesis and densification can be effected simultaneously. This new process, referred to as the high-frequency induction-heated combustion synthesis (HFIHCS), has been successfully used to synthesize and densify materials in one step in a relatively short period of time (2 min) [26][27][28].…”

Dense nanocrystalline 4TaSi 2 -Si 3 N 4 composite was synthesized by high-frequency induction-heated combustion synthesis (HFIHCS) method within 1 min in one step from mechanically activated powders of TaN and Si. Simultaneous combustion synthesis and densification were accomplished under the combined effects of an induced current and mechanical pressure. Highly dense 4TaSi 2 -Si 3 N 4 composite with relative density of up to 99% was produced under simultaneous application of a 60 MPa pressure and the induced current. The average grain size and mechanical properties (hardness and fracture toughness) of the composite were investigated.
