      The extensive use of metals over thousands of years, but in particular during the industrial age, can be attributed to their specific properties. In addition to their good electrical conductivityãassociated with good ...
    • Metallurgy of Heat Treatment and General Principles of Precipitation 

      J E Hatch (2013-12-03)
      The heat treatable alloys contain amounts of soluble alloying elements that exceed the equilibrium solid solubility limit at room and moderately higher temperatures. The amount present may be less or more than the maximum ...
    • Microstructure of Alloys 

      J E Hatch (2013-12-03)
      The examination of microstructure is one of the principal means of evaluating alloys and products to determine the effects of various fabrication and thermal treatments, evaluate the effects of new procedures, and analyze ...
