Heat Treating & Inspection

ASM HOMESTUDY COURSE (14 Lesson Series)

Course Overview:

This Course is designed to increase the technical knowledge of those involved in the heat treatment of metals and alloys. Emphasis is ion process control and quality control inspection procedures’ since both are necessary to provide heat treated products to meet industry standards and specifications.

Course Outline:

1. Mechanical Testing of Heat Treated Alloys: tension and compression; hardness (macro and micro) impact; bend and fatigue.

2. Nondestructive Inspection of Heat Treated Parts: liquid penetrant; magnetic particle; eddy current.

3. Metallographic Quality Control in Heat Treatment: sample preparation (sectioning, mounting, polishing and etching); photomicrography; interpretation of microstructures.

4. Hardening of Steel: proper hardening processes; quenching; hardening principles; isothermal and continuous cooling.

5. Tempering of Steel: three stages; effect of temperature; time; composition and structure on properties; precipitation effects.

6. Heat Treatment of Non-Ferrous Metals and Alloys: cold work, annealing and recrystallization; phase diagrams; heat treatment and mechanical properties

7. Instrumentation and Control I: measured variables; temperature; pressure; flow; furnace atmospheres.

8. Instrumentation and Control II: indicating and recording instruments; process control; solid state devices; typical control systems.

9. Furnace Atmospheres: primary furnace gases; prepared atmospheres; applications; carbon control; generating equipment.

10. Surface Hardening: flame, induction hardening; methods, reaction and effect of carburizing; discussion of miscellaneous surface hardening methods.

11. Induction Heat Treatment: fundamentals of heat treatment; equipment selection and processing parameters; technical considerations; applications.

12. Difficulties and Imperfections Associated with Heat Treated Steel: types of imperfections or failures; cracking types and causes; other imperfections.

13. Inspection Techniques and Sampling Methods: incoming, in-process and final inspection; quality control parameters; sampling; records; sampling risks.

14. Process Quality Control: control charts; variability; statistical basis; imperfection parameters; capability and tolerance.

Who Should Enrol:

Product development, quality control, design and process engineering, production, supervision, sales, and purchasing personnel involved in heat treating will find it a valuable technical education.

The Elements of Metallurgy course, is recommended as a prerequisite for those new to metallurgy.
