Book excerpt: Excerpt from Origin of Quenching Cracks During the investigation of the dimensional changes which tool steel undergoes on hardening, it was found that a 1-inch diameter cylinder was very susceptible to cracking when quenched in oil but not when quenched in water. Presumably the stresses produced by the faster quenching (the latter case) are greater than in the former, so evidence of the cause of failure under low stress and not under high was sought. Examination of the cracked specimens showed that failure was due to tensional stress at the surface. The axial stress at the surface after quenching in water was found by experiment to be compressional and high. It was concluded therefrom that hardened steel, like glass, is highly resistant to compressional stress but not to tensional stress. Conditions producing cracks In a particular Oil-hardening steel were determined experimentally. The Observations recorded show cracks are 'produced by permanent stress, which reaches a maximum value at ordinary temperatures. Permanent tensional stress can be produced at the surface by cooling only when the coefficient of expansion. Is negative and the steel is plastic. This condition was demonstrated from an experimental study Of the expansion Of steel during hardening. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a solid overview of the important metallurgical concepts related to the microstructures of irons and steels, and it provides detailed guidelines for the proper metallographic techniques used to reveal, capture, and understand microstructures. This book provides clearly written explanations of important concepts, and step-by-step instructions for equipment selection and use, microscopy techniques, specimen preparation, and etching. Dozens of concise and helpful “metallographic tips” are included in the chapters on laboratory practices and specimen preparation. The book features over 500 representative microstructures, with discussions of how the structures can be altered by heat treatment and other means. A handy index to these images is provided, so the book can also be used as an atlas of iron and steel microstructures.
