Front

What is the least dense material among the following: Ti64, Inconel 718, Stainless Steel 316, Aluminium 2024?

Back

Aluminium 2024 is the least dense material.

Front

Why are carbides not used for their ductility?

Back

Carbides are known for their hardness, temperature resistance, and wear resistance, but they are not ductile.

Front

Which material is generally more expensive: Titanium alloys, Nickel based alloys, Steel alloys, or Aluminium alloys?

Back

Nickel based alloys are generally more expensive.

Front

Which material is the most temperature resistant: Aluminium, Steel, Nickel based, or Titanium?

Back

Nickel based materials are the most temperature resistant.

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.

Front

What is the role of austenitic stainless steels in corrosion resistance?

Back

Austenitic stainless steels have a high chromium content, which provides excellent corrosion resistance.
