Magnesium Alloys
Magnesium alloy developments have traditionally been driven by aerospace industry requirements for lightweight materials to operate under increasingly demanding conditions. Magnesium alloys have always been attractive to designers due to…
Aluminum alloys
Aluminum has a long and successful history in aerospace. As far back as the 19th century, Count Ferdinand Zeppelin used it to make the frames of his iconic airships, demonstrating…
WHAT IS THE ROLE OF STEEL IN AIRCRAFT?
A good grasp of technical knowledge encompassing mechanical properties, chemical composition, and corrosion resistance of the material is crucial to design and fabricate any critical equipment such as those used…
Stress corrosion cracking
Stress on aircraft parts may be residual within the part as a result of the production process or externally applied cyclic loading. Press-fit bushings, tapered bolts and severe metal forming…
Types of corrosion normally found on aircraft include
Uniform surface attack. This is the most common type and is caused simply by exposing the metal to oxygen in the air, such as when paint is worn off wing skin…
Aircraft Corrosion
DVI’s Aircraft Corrosion Experts are capable of evaluating corrosion failures involving steels, stainless steels, copper alloys and aluminum alloys. Many cases require highly specialized testing equipment, and DVI’s Aviation Corrosion Experts have close…
WHAT IS A COMPOSITE MATERIAL?
A composite material is a combination of two materials with different physical and chemical properties. When they are combined they create a material which is specialised to do a certain…
Bauschinger effect
The Bauschinger effect refers to a property of materials where the material's stress/strain characteristics change as a result of the microscopic stress distribution of the material. For example, an increase in tensile yield strength occurs at…
Strain Hardening
After a material yields, it begins to experience a high rate of plastic deformation. Once the material yields, it begins to strain harden which increases the strength of the material.…
What is Yield Strength?
Whether an object is stubborn or malleable is decided by the yield strength. It is the point at which an object ceases to be elastic and becomes plastic. Yield strength helps us…
