    Scale effects for strength, ductility, and toughness in ...

    Decreasing scales effectively increase nearly all important mechanical properties of at least some "brittle" materials below 100 nm. With an emphasis on silicon nanopillars, nanowires, and nanospheres, it is shown that strength, ductility, and toughness all increase roughly with the inverse radius of the appropriate dimension.

    Mar 12, 2013· iom3 :"We identified a special temperature that tells you whether you form a ductile or brittle glass," explains Jan Schroers, a professor of mechanical engineering and materials science at Yale, who led the research together with Golden Kumar, a professor at Texas Tech University. To make a glass that is ductile, it must be cooled quickly – the exact speed depending on the properties of ...

    DUCTILETOBRITTLE TRANSITION TEMPERATURE IN STEEL .

    Aug 01, 2011· Best Answer: The temperature varies with the type of low carbon steel and how it is heat treated. Common structural steel actually have a transition temperature as defined by Charpy impact tests to be in the 50 degree range. Most low carbon steel pipe such as ASTM A53, A106 and pressure vessel plate such as A212, a515 also have 50 degree range Charpy test results.

    Ductile regime grinding[31 can be used to provide a damage free surface. Cranfield Precision carried out comprehensive grinding research on a number of different brittle materials and confirmed that there exists a transition "depth of cut" from ductile to brittle mode fracture with depths of cut of around 0. lum. This transition "depth of
