One of the common characteristics for intermetallics is their brittleness at ambient temperatures. Some intermetallics like those called sigma, mu and Laves phases are typical examples that are sometimes detrimental to the ductility and toughness of steels once incorporated unexpectedly. Of surprise to notice is that even, fundamentals for plasticity such as operating slip systems and their CRSS values have yet to be known for many of them. However, there is a chance for these hard materials to plastically deform in the form of micropillars of the micron-meter size even at ambient temperature, from which we can obtain the information of operating slip systems and their CRSS values. The results obtained for some brittle intermetallics incorporated in steels (FeCr, Fe2Ta and Fe3C) will be presented.
