#### LibraryThing Review

User Review - all4metals - LibraryThingThis is one of the best textbooks on physical metallurgy. My preference is for Dieter's book, but that is because it was the textbook for my physical metallurgy course in graduate school. Hertzberg's book is more modern. Read full review
