Front

Which statement is correct regarding low alloyed steels and austenitic stainless steels?

Back

Austenitic stainless steels don't need ageing thermal treatments.

Front

Define 'ductility' in materials science.

Back

Ductility is the ability of a material to deform under tensile stress, often characterized by the material's ability to be stretched into a wire.

Front

What are the primary characteristics of Nickel based alloys?

Back

Nickel based alloys are known for their high temperature resistance, corrosion resistance, and strength.

Front

What is the significance of using Aluminium 2024 in aerospace applications?

Back

Aluminium 2024 is valued for its high strength-to-weight ratio and good fatigue resistance.

Front

Explain why carbides are preferred for wear resistance.

Back

Carbides are extremely hard materials, making them ideal for applications requiring high wear resistance.
