Principles of Heat Treatment

The National Composites Centre (NCC) is delighted to work in collaboration with the AMRC to deliver this course.

This course is being run at The National Composites Centre by AMRC - BOOK HERE

Course aims
This course outlines the basic metallurgical principles of heat treatment, the fundamentals of furnace design & operation and concludes with an explanation of testing & quality control procedures.
 

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

A module of the QCF level 3 Certificate in Metallurgy qualification

Course Duration: 1 day

Price: £400

LEARNING OUTCOMES
• Explain why heat treatment is required for steels, nickel, titanium and aluminium alloys
• Appreciate the influence of heat treatment on microstructure and hence on materials properties
• Compare and contrast the attributes and control characteristics of electrical resistance, induction, gas and fuel oil fired furnaces
• Specify physical test procedures and explain their relevance in a formal quality control environment
