A new device for conducting tensile and compressive tests at strain rates ranging from about 20 s−1 to 250 s−1 is presented. The operation of the device is based on the principles of the Split Hopkinson Bar (SHB) technique, except that the incide

Mechanical properties of most metallic materials can be improved by reducing their grain size. One of the methods used to reduce the grain size even to the nanometer level is the severe plastic deformation processing. Equal Channel Angular Pressing (

Nanocrystalline and ultrafine-grained materials show many very interesting properties compared to the conventional coarse-grained materials. For example, their strength values are usually much higher but, on the other hand, their ductility and deform
