Introduction
index
Heat treatment aims to improve the mechanical properties of the alloy, increase the elastic limit and reduce brittleness.
What is a heat treatment?
The different types:
Annealing
Standardization
Hardening
Tempering
heat treatments
What it consists of/how it is processed
annealing heat treatment
makes the material less rigid and easier to use.
makes the metal more malleable, making it easier to mold without running the risk of breaking.
Prevents problems such as cracking or spontaneous deformation during the use of the metal.
eliminate internal tensions
Reduce hardness
Improve ductility
The main objectives
- Maintenance of mechanical parts;
- Component manufacturing;
- Component repair.
In the aircraft industry, annealing heat treatment is widely used to improve the structural and mechanical performance of aircraft. Within its varied uses we have:
In aeronautics
Lack of adequate heat treatment can lead to several risks in aeronautics. A classic example involves aircraft fuselage. In the 1980s, Aloha Airlines Flight 243 suffered an explosive decompression due to fatigue cracks in areas of metal alloy.
