Study Notes
Materials Used in Indian Railways
- Indian Railways commonly uses steel and stainless steel for their infrastructure and equipment
Role of Nickel in Ferrous Materials
- Nickel is used to enhance corrosion resistance and improve the strength of ferrous materials
Element Found in Certain Alloys
- Copper is a common element found in brass, bronze, and bearing alloys
Bend Test
- The Bend Test is used to evaluate the ductility of materials, specifically their ability to bend without breaking
Non-Destructive Testing (NDT)
- Radiography is a commonly used method for non-destructive testing (NDT) in materials inspection, allowing for the examination of internal structures without causing damage
Iron-Carbon Diagram
- The Iron-Carbon diagram is used to determine the microstructure and properties of steel, particularly in heat treatment processes, helping to predict the final product's characteristics
