Abstract
This chapter evaluates the microstructure and its impact on EAF. This chapter is divided into three sections where Sect. 8.1 discusses the impact that different starting grain sizes have on the thermal and mechanical profiles of EAF in compression. Section 8.2 evaluates differences in starting dislocation density (from specimen pre-working) and how they impact mechanical EAF profiles. Section 8.3 provides analysis for post-formed microstructure of tensile sheet specimens using statistical methods. To illustrate these concepts, the chapter contains experimental testing and analysis.
