The strength of engineering systems in the range of ~ 1 micron to 1 mm offers particular challenges in testing and in understanding materials behaviour. In recent times, a number of testing methods have been introduced that combine one or more of micromechanical handling, in-situ observation and full field deformation measurements. Such techniques have allowed the detection of behaviour as diverse as plastic flow in small samples of silicon, brittle behaviour in copper, steep R-curves in a high pressure form of silica that undergoes transformation toughening and so on. After a brief review, this talk will focus on three examples of laboratory work on metallurgical systems.
