Q1. What are the key features of the iron-carbon diagram, including its important phases and corresponding temperatures?
Ans. 
The iron-carbon diagram illustrates the phases and transformations of iron and carbon alloys at varying temperatures.
• The diagram includes key phases: ferrite (α), cementite (Fe3C), austenite (γ), and liquid iron.

• Ferrite is stable up to 912°C and has a body-centered cubic (BCC) structure.

• Austenite forms between 727°C and 1394°C, characterized by a face-centered cubic (FCC) structure.

• Cementite is stable at all temperatur...read more

Q2. What is the structure of a blast furnace, and what are the important zones and the temperatures maintained within them?
Ans. 
A blast furnace is a large structure used for smelting iron, featuring distinct zones with varying temperatures for efficient metal production.
• The blast furnace consists of several zones: the top, the bosh, the hearth, and the tuyere zone.

• The upper zone (charging zone) operates at around 200-400°C, where raw materials like iron ore, coke, and limestone are added.

• The bosh zone, located below the charging zone, reaches t...read more

Q3. What is the process of centrifugal casting and how is alloy addition performed?
Ans. 
Centrifugal casting is a process that uses centrifugal force to produce cylindrical metal parts with uniform density and strength.
• Centrifugal casting involves pouring molten metal into a rotating mold.

• The rotation creates a force that distributes the metal evenly against the mold walls.

• This process is ideal for producing cylindrical shapes like pipes and tubes.

• Alloy addition can be performed by mixing different metals ...read more

Q4. What is the importance of stress-strain curve, what are the mechanical testings done.
Ans. 
The stress-strain curve is crucial for understanding material behavior under load, guiding design and safety in engineering applications.
• Illustrates material properties: The curve shows how materials deform under stress, indicating elastic and plastic behavior.

• Determines yield strength: The point where the curve deviates from linearity indicates the yield strength, essential for design limits.

• Identifies ultimate tensil...read more

Q1. What is the lathe machine and their working function?
Ans. 
A lathe machine is a tool used for shaping materials by rotating them against a cutting tool.
• Lathe machines are used for turning, drilling, cutting, sanding, and knurling materials.

• They work by rotating the material on its axis while a cutting tool is applied to shape it.

• Examples of lathe machines include CNC lathes, engine lathes, and turret lathes.

Q2. What is the galvanized process?
Ans. 
Galvanization is the process of applying a protective zinc coating to steel or iron to prevent rusting.
• Involves dipping the metal into a bath of molten zinc

• Forms a layer of zinc on the surface of the metal

• Provides corrosion resistance to the metal

• Commonly used in construction for structures like bridges, pipelines, and fences

Q2. Why annealing we needed?
Ans. 
Annealing is needed to relieve internal stresses, improve ductility, and soften the material for further processing.
• Annealing helps to remove internal stresses in the material, making it more ductile and less prone to cracking.

• It also helps to soften the material, making it easier to shape or machine.

• Annealing can improve the microstructure of the material, leading to better mechanical properties.

• Examples of materials ...read more
