Transformations in Metals

The Distinguishing Characteristic Of A Metallurgist (Or Ceramist) Is An Ability To Work Effectively With Materials In Which The Properties Depend On The Microstructure Evolved Through Prior Treatment. These Effects Of Prior History Are Commercially Important And Usually Too Complex To Yield To Any Detailed Mathematical Analysis. This Book Provides An Introduction To The Concepts Used In Understanding The Evolution Of Microstructure. It Stems From A Two-Semester Course Taught To Juniors In Metallurgy Who Had Had A Prior Course Dealing With The Atomic Structure Of Solids, Simple Crystals, Defects, And The Existence Of Phase Diagrams. It Differs From The Several Books On Physical Metallurgy In That It Covers Fewer Topics In More Depth. The Sequence Has Been Chosen To Go From The Simpler To The More Complex. Thus The Material On Dislocations And Diffusion Covered In The First Chapters Is Used Again In Discussing Recovery And Solidification, The Nucleation And Solute Redistribution Concept Covered In Solidification Are Used Again In Treating Phase Transformation In Solids, Etc. The Order Of Chapters And Material Has Been Chosen To Allow The Introduction Of As Few New Concepts Per Chapter As Possible, And The Reinforcing Of These Concepts In The Students Mind By Using Them Again And Again In Subsequent Sections. This Learning By Using Probably Reaches An Extreme In The Case Of Phase Diagrams, Which Are Not Given The Customary Full Development In One Chapter But Are Introduced In Chap.4, And Then Used Extensively And Further Developed In Chaps.5, 6,7,And 8. In This Way The Material Is Presented Not In The Abstract But As An Essential Tool In Discussing Reactions Occurring At And Near Equilibrium.
