Kharagpur Metal Reforming Industries Quality Control Trainee Interview Questions, Process, and Tips

Heat treatment is a process of heating and cooling metals to alter their physical and mechanical properties.

• Heat treatment is used to improve the strength, hardness, toughness, and ductility of metals.

• It involves heating the metal to a specific temperature and holding it there for a certain amount of time before cooling it down.

• Different types of heat treatment include annealing, quenching, tempering, and normalizing.

Foundry is a factory that produces metal castings.

• Foundries melt and pour metal into molds to create castings.

• They use various metals such as iron, steel, aluminum, and copper.

• Foundries are used in industries such as automotive, aerospace, and construction.

• Quality control is important in foundries to ensure the castings meet specifications.

Casting is a manufacturing process in which a liquid material is poured into a mold and allowed to solidify.

• Casting is used to create complex shapes that would be difficult or impossible to make using other methods.

• The most common materials used for casting are metals, but plastics and ceramics can also be cast.

• There are several different types of casting, including sand casting, investment casting, and die casting.

• Cas...read more

Stress strain diagram shows the relationship between stress and strain in a material.

• Stress is the force applied per unit area of a material.

• Strain is the deformation or change in shape of a material due to stress.

• The diagram plots stress on the y-axis and strain on the x-axis.

• The slope of the curve represents the material's stiffness or Young's modulus.

• The area under the curve represents the energy absorbed by the mat...read more
