About the course

Course Description

  • Heat treatment is a controlled process used to alter the microstructure of metals and alloys such as steel and aluminium to impart properties which benefit the working life of a component, for example increased surface hardness, temperature resistance, ductility and strength.
  • Heat treatment processes include case hardening, tempering, solution and ageing treatment, annealing and normalising.
  • Knowledge of the fundamentals of the processes is extremely critical to achieve the desired metallurgical and dimensional properties of parts heat treated.
  • We are therefore pleased to make this online course available to heat treatment professionals.

This course will cover all important aspects about the different types of Heat treatment processes.

Please refer to the Course Content section below for more details.

Course Objective

The objective of the course is to

  • Provide thorough knowledge of the fundamental principles of various types of Heat treatment processes.
  • Provide in-depth knowledge about the critical process parameters involved and also guidelines for trouble shooting.
  • The practical approach will help to improve the processes on the shop floor, thereby reducing rejections, rework and wastage and improve quality and customer satisfaction.

What am I going to get from this?

By registering for this course, you can get thorough knowledge about the fundamental metallurgical principles of various types of Heat treatment processes, critical process parameters, practical trouble shooting tips, etc. With this knowledge, you can improve your processes, eliminate rework and rejections, improve quality of heat treatment and improve customer satisfaction.
When you register for the course you will get,

  • Video Lectures / Study Notes / Self-assessment Quiz
  • Opportunity to discuss queries with the trainer
  • New ideas to solve existing issues or make improvements
  • Achieve significant reduction in rework / rejection costs
  • Course Completion Certificate
  • Enhanced career prospects

Implement as you learn

A lot of classroom training goes waste because most of it is never implemented. The main reason for the same is that you are not in touch with the trainer and if you face any issues in implementation, trainer’s guidance is not available to you.

  • On, unlike class-room training, the course duration is longer and you have a chance to absorb new concepts and try and implement them on the job.
  • This is where the discussion forum comes in handy as it will help you to directly interact with the trainer. You get to discuss real- time issues / queries with the trainer on the said topic.
  • The trainer, owing to his vast experience will provide solutions to your queries and issues. This should motivate you to implement the concepts immediately on the shop floor and solve any issues you may be facing.
  • This will have tremendous long term benefits as your new practices could lead to reduced costs, reduced rework, rejections and improve quality.

Who should take this course?

This course shall be useful to every heat treatment professional involved in Heat treatment. Specifically, this course would be useful to heat treatment professionals working in the following industries:

  • Commercial heat treaters
  • OEM auto manufacturers
  • Auto component manufacturers
  • Forging industry
  • Bearing industry
  • Fastener industry
  • Farm equipment industry
  • Steel industry
  • General engineering industry
  • Defence industry
  • Furnace manufacturing industry

Metallurgical Students / Freshers can also greatly benefit from this course because they will get industry oriented training, making them job ready.

Note: This course will be extremely useful for people who are working in heat treatment industry but don’t have formal metallurgical education.


Certificate of course completion shall be awarded to every registered student after satisfactory completion of the course.

  • After going through the study material, the student will be required to clear the on-line self-assessment quiz.
  • On clearing the on-line quiz, the student will be interviewed by the trainer, Mr. David Pye on skype.
  • On satisfactory performance at the interview, a certificate of course completion shall be personally signed and issued by the trainer.

Once you enroll for the course, You can login to your Student account. Here you will find the Study Notes (PDF), Video Lectures, Self-assessment Quizzes and links to Discussion Forums all at one place. You can now watch the video lectures and go through the notes until you have fully grasped the concepts. In case you have any queries about concepts or their implementation, you may post your queries in the discussion forum for the trainer to answer. Once you are confident about the topic you may take a quiz to self assess your understanding of the concepts. When you are through with all chapters, an online interview with the trainer will get you a Completion certificate.
