    Metallography of Steels: Interpretation of Structure and the Effects of Processing

    Published: 2018
    Authors: Hubertus Colpaert

    This book is a combination of a metallographic atlas for steels and cast irons and an introductory textbook covering the fundamentals of phase transformations and heat treatment of these materials. Every important stage of processing, from casting to cold working is clearly discussed and copiously illustrated with metallographs that show the obtained structures, both desired and those achieved when deviations occur. A valuable companion even for experienced steel practitioners.

    One Minute Mentor: Nitrocarburizing in a Carrier Gas

    August 31, 2017

    Nitrocarburizing in a carrier gas to which (initially solid) urea was added led to a fast growth of the expanded austenite zone. The gaseous decomposition products of urea that develop in the furnace are highly activating, which means that activation and nitrocarburizing are achieved simultaneously.
