      The data set was used to evaluate a Fe-Cr-Al thin film samples in a narrow composition region centered on known bulk compositions. The data are composed of two individual studies. The first set of data is a low temperature ...
    • Hydrostatic Extrusion of Metals and Alloys 

      J.J. Lewandowski and A. Awadallah (2013-12-03)
      IN HYDROSTATIC EXTRUSION, the billet is extruded through a die via the action of a liquid pressure medium instead of the direct application of the load through a ram. In cases of hydrostatic extrusion, the billet is ...
