Compressibility Behaviour and Green Density of Metal/PZT Powder

Titanium iron and stainless steel are commonly used in structural engineering applications. Conversely, piezoceramics materials have been widely used in engineering applications for their functionality. Combining both materials could open up the opportunity to have a novel structural-functional material that can be beneficial in smart cities. However, pressing those two types of materials remains a challenge due to their different deformation properties. This study investigates the compressibility behaviour of metal/piezoceramics powder composites in different pressing techniques. The effect of different parameters explored in this study such as pressing method, and pressure rate. Raw powders were pressed individually, the warm pressing technique was suitable to press metallic matrices. On the other hand, the need to investigate different pressure rates was necessary to understand the compressibility behaviour of the ceramic powder. It has been found that the warm press technique was applicable to press the designed metal/piezoceramics powder mixtures.
