The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.
Entropy in a closed system tends to increase over time
Heat energy naturally flows from hot to cold objects
Efficiency of energy conversion processes is limited by the second law of thermodynamics
Creep is the slow, time-dependent deformation of a material under constant load, while fatigue is the weakening of a material due to repeated loading and unloading.
Creep is a time-dependent phenomenon, while fatigue is a cyclic phenomenon.
Creep occurs at high temperatures and constant stress, while fatigue occurs at lower temperatures and varying stress levels.
Creep leads to permanent deformation, while fatigue can lea...
A thermocouple is a temperature sensor that consists of two different metals joined together at one end, which produces a voltage proportional to the temperature difference between the junction and the other end.
Consists of two different metals joined together at one end
Produces a voltage proportional to the temperature difference
Commonly used in industrial applications for temperature measurement
T-t-t diagram is a time-temperature-transformation diagram used in materials science to understand the transformation of phases in a material.
T-t-t diagram shows the relationship between time, temperature, and the transformation of phases in a material.
It helps in predicting the microstructure of a material based on the cooling rate and temperature.
T-t-t diagrams are commonly used in metallurgy to understand the phase
Annealing is a heat treatment process used to soften metals and increase their ductility.
Annealing involves heating a metal to a specific temperature and then slowly cooling it to room temperature.
This process helps to relieve internal stresses, improve machinability, and enhance electrical conductivity.
Examples of metals that are commonly annealed include steel, copper, and aluminum.
The critical temperature of steel is the temperature at which it loses its magnetic properties.
The critical temperature of steel is around 770°C (1420°F).
Above this temperature, steel becomes non-magnetic and undergoes a phase change.
The critical temperature varies depending on the type of steel and its composition.
Types of steel include carbon steel, alloy steel, stainless steel, and tool steel. They can be differentiated based on their composition, properties, and applications.
Carbon steel contains primarily carbon and iron, with low amounts of other elements. It is commonly used in construction and manufacturing.
Alloy steel contains additional elements such as manganese, silicon, and copper to enhance its properties. It is use...

Manufacturing defects are flaws or imperfections in a product caused during the manufacturing process.
Manufacturing defects can occur due to errors in design, materials, or production processes.
Examples of manufacturing defects include cracks in a car's engine block, missing stitches in a garment, or a misaligned circuit board in an electronic device.
Manufacturing defects can lead to product failures, safety hazards, a...
Steels are alloys of iron and carbon with varying properties depending on their composition and heat treatment.
Strength and hardness depend on carbon content and heat treatment
Ductility and toughness depend on alloying elements and heat treatment
Corrosion resistance depends on the presence of alloying elements such as chromium
Magnetic properties depend on the crystal structure and alloying elements
Weldability and machi...
The best manufacturing process depends on the product being manufactured and its requirements.
Each manufacturing process has its own advantages and disadvantages.
For example, injection molding is best for mass production of small and complex parts, while CNC machining is better for low-volume production of larger parts.
The choice of manufacturing process also depends on factors such as cost, time, and quality requireme...

Two topics was provided.
I applied via Campus Placement and was interviewed before Mar 2022. There were 2 interview rounds.
Normalizing and quenching are heat treatment processes used to alter the properties of metals.
Normalizing involves heating the metal to a temperature above its critical point and then cooling it in still air. This process improves the uniformity of the metal's grain structure and reduces internal stresses.
Quenching involves heating the metal to a high temperature and then rapidly cooling it in a liquid, usually water o...
Ferrous metals are those that contain iron as their main constituent.
Ferrous metals are magnetic and have high tensile strength.
They are used in construction, manufacturing, and transportation industries.
Examples include steel, cast iron, and wrought iron.
The formula for steel is Fe+C, for cast iron is Fe+C+Si, and for wrought iron is Fe+C+Si+Mn.
I applied via Naukri.com and was interviewed in Jul 2021. There were 3 interview rounds.
