The microstructure and micro-hardness of tungsten carbide/high strength steel (WC/HSS) composites with different particle sizes were analyzed by optical microscopy (OM), scanning electron microscopy (SEM), ultra-high temperature laser confocal microscopy (UTLCM) and micro-hardness testing. The composites were prepared by cold pressing and vacuum sintering. The results show that WC density tends to increase as the average grain size of WC decreases and the micro-hardness of WC increases with the decrease of WC particle size. The micro-hardness of WC near the bonding interface is higher than that in other regions. When the particle size of WC powder particles is 200 nm, a transition layer with a certain width is formed at the interface between WC and HSS, and the combination between the two materials is metallurgical. The iron element in the HSS matrix diffuses into the WC structure in contact with it, resulting in a fusion layer of a certain width, and the composite interface is relatively well bonded. When the average particle size of WC powder is 200 nm, W, Fe and Co elements significantly diffuse in the transition zone at the interface. With the increase of WC particle size, the trend of element diffusion decreases.

The results of tests on two high-strength steels, beryllium copper and perspex, together with some published data on high-strength steels were examined to see whether there was any relationship between the fracture mechanics parameter K1C and conventional mechanical properties. It was found that for steels and beryllium copper a correlation appeared to exist between K1C and the zero gauge length strain (= Z/(1 - Z) where Z is the reduction of area measured in a tensile test). It was also found that for constant, K1C was proportional to the square root of Young's modulus. The correlation band for steels was too wide for K1C to be estimated accurately from.

Pulse electrochemical micromachining (PECMM) is a non-conventional manufacturing method suitable for the production of micro-sized components on a wide range of conductive materials. PECMM improves dimensional accuracy and simplifies tool design in machining hard, high strength, and heat resistant materials into complex shapes. Extremely small interelectrode gaps are required in PECMM for better dimensional accuracy. However, excessively small interelectrode gaps may lead to complications like short-circuiting. This imposes the need for better control of the PECMM process. In this study a feedback controlled PECMM system was developed for the electrochemical micromachining of tungsten carbide. It was noticed that while, higher ratios of return velocity to feed rate is preferred as it reduces the number of current spikes, very high value of this ratio results in poor machining rates due to increased interelectrode gap. Therefore, this ratio of return velocity to feed rate may be used to optimize the PECMM process.
