"Metallographer’s Guide: Practicesand Procedures for Irons and Steels" by Bruce L. Bramfitt, Arlan O.Benscoter
ASM | 2002 | ISBN: 0871707489 9780871707482 | 365 pages | PDF | 35 MB
This guide was prepared not only for the beginningmetallographer but also for the experienced metallographer who may be lookingfor alternatives and new approaches to metallographic practice. For thebeginning metallographer, little or no knowledge of steels and cast irons theguide provides the basic information needed to understand the various types ofsteels and cast irons available in the commercial world; provides examples ofthe multitude of microstructures that the metallographer will encounter, howthese microstructures are created, and how they can be altered by heattreatment and other means. Some metallographers may be working in a smalllaboratory where no metallurgical support is available.
A unique feature of this guide is a separate andcomplete index of the various steels and cast irons used as examples throughoutthe book. The index makes the hundreds of micrographs essentially an Atlas ofMicrostructures.
Although this book is for the novicemetallographer, an experienced metallographer may find it useful in that dozensof special metallographic tips are scattered through the chapters on specimenpreparation and the art of revealing microstructure. This guide could be usedas a university or technical school text to accompany the teaching of alaboratory course in metallography.
