ENGR 0022 Study Guide - Midterm Guide: Basic Oxygen Steelmaking, Electric Arc Furnace, Alloy Steel
Document Summary
Study guide exam 1: refining and shaping of metals and alloys. Reduction of iron ore in the blast furnace (you must know equations). Description of basic oxygen furnace (bof) processing of steel. Description of electric arc furnace (eaf) processing of steel. Description of continuous casting and the shapes of the intermediate forms (you do not need to know dimensions). Definitions of plain carbon steels: low carbon, medium carbon, and high carbon. Definitions of low alloy steel and stainless steel. Bayer process for removing iron contamination from bauxite to produce aluminum oxide. Definitions of true stress and true strain and comparison with engineering stress and engineering strain. Basic differences between cold work, warm work, and hot work. Microstructural processes of recrystallization and changes in properties. Effect of annealing time and % cold work on recrystallization temperature. Work hardening: relationship between flow stress and strain, definition of average flow stress.
