A one day course providing delegates with a sound understanding of the beneficial effects of heat treatment to a range of ferrous & light metal alloys.

Course aimsThis course outlines the basic metallurgical principles of heat treatment for steels and non-ferrous alloys. Strengthening by manipulation of the microstructures of steels, Aluminium, Titanium, Nickel & Magnesium alloys are explained. The course concludes with a description of case hardening procedures.

Who should attendAnyone requiring an overall understanding of the practicalities of heat treatment. This includes purchasers and vendors of heat treatment services, design engineers and quality control technicians.

The course is complemented by ‘Practicalities of Heat Treatment’.

Principles of Heat Treatment

Why Heat Treat?• Basics of physical metallurgy

• Mechanical testing – hardness, toughness, strength

• Improving mechanical properties

• Removing internal stresses

• Improving machinability

• Improving surface properties

• Improving electrical properties

• Improving magnetic properties

Strengthening Mechanisms• What is strength?

• Crystallography of metals

• Equilibrium phase diagrams

• Lattice strain

• Dislocations & precipitates

• Solid solution strengthening

• Martensitic transformations

• Grain size & grain boundaries

Heat Treatment of Non-Ferrous Alloys• Aluminium Alloys

• Titanium Alloys

• Nickel Alloys

• Magnesium Alloys

Heat Treatment Terminology• Homogenisation

• Solution treatment

• Normalising

• Annealing

• Precipitation treatment

• Tempering

• Ageing

• Stress relieving

Heat Treatment of Ferrous Alloys• Iron-Carbon Phase diagram

• TTT Curves

• CCT Curves

• Austenite, Ferrite, Pearlite, Bainite, Martensite

• Hardenability

• Annealing

• Quench & Tempering

• Stress Relieving

Case Hardening & Induction Hardening• Carburising

• Nitriding

• Carbo-nitriding

• Induction hardening

• Sub-zero treatments

LEARNING OUTCOMES• Explain why heat treatment is required for steels,

Aluminium, Titanium & Nickel alloys

• Appreciate the influence of heat treatment on

microstructure and hence on materials properties

• Specify practical heat treatment procedures to

achieve desired effects in a range of alloy types

• Understand the heat treatment procedures used to

modify surface properties of steels
