Course Objectives To enable materials engineering students to prepare and examine metallographic specimens and to enable them to recognize and evaluate macro and microstructures of metallic materials
Course Learning Outcomes The students who succeeded in this course;
  • Students learn techniques of specimen preparation.
  • Students are acquainted with techniques of optical microscopy and electron microscopy.
  • Students can recognize different phases in both ferrous and nonferrous microstructures and thus identify alloys.
  • Students can quantify grain size, phase percentages and classify and quantify inclusions.
  • Students become able to correlate microstructure, composition and mechanical properties.
Course Content Metallographic specimen preparation; etching techniques; precipitate and phase recognition; analysis of metallic microstructures; quantitative and qualitative metallographic analysis.
