Online Course - Metallurgical Properties, How to Measure, Assess and Influence

In this course of 3 modules we will look at how material properties are measured, assessed and can be influenced by processing.

The course will concentrate on how key mechanical properties are measured in practice; the key features of microstructures formed during processing and how these microstructures are observed using optical microscopy and scanning electron microscopy and how microstructure and therefore mechanical properties are changed by heat treatment processes. The course will refer to terminology and principles covered in the course Building Blocks for Metallurgical Success, so it is recommended that that course is completed ahead of undertaking this course.

On demand and instant access to the full course consisting of three modules.

To maximise learning it is recommended that each module is completed in sequence.

Course Modules

The course consists of three modules which should be taken in sequence in order to complete the full course.

Module 1 – Mechanical Properties and Mechanical Testing

This module will recap on what is meant by strength and toughness and look at the standard test methods and equipment by which they are determined. The methods by which hardness, creep and fatigue are measured are also discussed. The module will also cover how strength, toughness and creep are influenced by grain size.

Module 2 – Microexamination and Microstructures

This module will recap on how microstructures in steel are formed, which was covered on the atomic scale in the first course Building Blocks for Metallurgical Success, and look at the key microstructural features by which the metallographer can distinguish between differing microstructures and how in practice microstructures are assessed using optical microscopy and scanning electron microscopy.

Module 3 – Heat Treatment

This module will consider how the properties and microstructure discussed in modules 1 & 2 are achieved in practice. The module will discuss the heating and cooling parameters that are used to achieve a desired property outcome.

What the course covers

  • Recap on definition of strength, ductility and toughness
  • Recap on the influence of grain size on strength and toughness
  • Practical methods by which, strength, ductility, toughness, hardness, creep and fatigue are measured
    • Tensile test
    • Charpy and CTOD test
    • Brinell and Vickers hardness test
    • Creep testing
    • Fatigue testing
  • Recap on Fe-C phase diagram and formation of equilibrium ferrite and pearlite
  • Recap on how martensite and bainite are formed
    • What are the key features which differentiate how ferrite and pearlite, bainite and martensite look like in practice
    • How samples are prepared and etched for microstructural assessment
    • How these microstructures are observed under an optical light microscope
    • What features can be distinguished using a scanning electron microscope
  • Recap on the rules governing Time-Temperature-Transformation and Critical Cooling Rate
  • How these rules are applied in through practical heat treatment to achieve desired properties
    • Parameters required for annealing and the property outcome
    • Parameters required for normalising and the property outcome
