TTT diagram is a Time-Temperature-Transformation diagram used in materials science to understand the transformation of phases in a material.
TTT diagram shows the relationship between temperature, time, and phases in a material during cooling or heating.
It helps in predicting the microstructure and properties of a material based on its cooling rate.
TTT diagrams are commonly used in heat treatment processes for metals li...
Ceramic is a non-metallic material made from clay, while steel is a metallic material primarily made from iron and carbon.
Ceramic is non-metallic, while steel is metallic
Ceramic is made from clay, while steel is primarily made from iron and carbon
Ceramic is typically more brittle than steel
Steel is stronger and more durable than ceramic
Ceramic is often used for decorative purposes or in high-temperature applications, w...
Fatigue is the weakening of a material due to repeated loading, while creep is the gradual deformation of a material under constant stress.
Fatigue is the process of progressive and localized structural damage that occurs when a material is subjected to cyclic loading.
Creep is the time-dependent deformation of a material under constant load or stress.
Fatigue failure is often characterized by crack initiation and propaga...
Different types of steel making include basic oxygen furnace, electric arc furnace, and open hearth furnace.
Basic Oxygen Furnace (BOF) - uses oxygen to reduce the carbon content in the steel
Electric Arc Furnace (EAF) - uses electricity to melt scrap steel and produce new steel
Open Hearth Furnace - uses a fuel-air mixture to heat the steel and remove impurities
Other methods include Bessemer process, direct reduced iron,
Alloying elements are used in steel making to improve properties like strength, hardness, corrosion resistance, and machinability.
Alloying elements are added to steel to enhance specific properties such as strength, hardness, toughness, and corrosion resistance.
Common alloying elements include chromium, nickel, manganese, molybdenum, and vanadium.
Chromium is added to improve corrosion resistance, nickel for toughness, ...
SN curve is a graphical representation of the relationship between stress and fatigue life of a material.
SN curve shows the number of cycles to failure (N) against the applied stress (S).
It helps in determining the fatigue life of a material under different stress levels.
Materials with higher fatigue strength have a steeper slope on the SN curve.
SN curves are commonly used in engineering to predict the durability of ma
Pig iron is an intermediate product of the iron industry, made by smelting iron ore in a blast furnace.
Pig iron is typically around 92-94% iron, with varying amounts of carbon, silicon, manganese, sulfur, and phosphorus.
It is brittle and not suitable for use in its raw form, but can be further processed into wrought iron or steel.
The carbon content of pig iron gives it a high carbon equivalent, making it ideal for cast...
Lever rule is a principle used in material science to determine the relative amounts of two phases in a two-phase system.
Lever rule is used to calculate the fraction of each phase in a two-phase system based on the weight or volume percentages of the phases.
It is commonly used in metallurgy, ceramics, and other material science fields.
The lever rule equation is: L = (C - A) / (B - A), where L is the fraction of one pha...

I applied via Campus Placement and was interviewed before May 2023. There were 2 interview rounds.
We discussed topics like Industrialisation in North East India and Mizoram, also Discussed about Environmental Impact by industrialisation
Laws of Thermodynamics are fundamental principles governing energy and heat transfer in physical systems.
First Law: Conservation of energy - energy cannot be created or destroyed, only transferred or converted.
Second Law: Entropy always increases in isolated systems, meaning energy tends to disperse and become less usable.
Third Law: As temperature approaches absolute zero, entropy approaches a minimum value.
Examples: A...

I applied via Campus Placement and was interviewed in Feb 2024. There were 3 interview rounds.
It Consists of 2 Sections.
One is Pure Aptitude and other is Core.
They divided us into group of 6 members and the topic was effect of e-learning on Students.
The wheels of a locomotive diesel engine come to action through a process called combustion, where fuel is burned to generate power.
Fuel is injected into the combustion chamber
The fuel is ignited by a spark plug or compression
The burning fuel creates high-pressure gases that push the pistons
The pistons turn the crankshaft, which is connected to the wheels
The rotational motion of the crankshaft is transferred to the whe

Copper is extracted from ore through several stages including crushing, grinding, and concentration.
The ore is first crushed into small pieces
It is then ground to a fine powder
The powder is then concentrated using various methods such as froth flotation
The concentrated ore is then roasted to remove any remaining impurities
Finally, the copper is extracted using electrolysis or smelting
The final product is usually in the
Electrorefining, electrowinning, and electroplating are all electrochemical processes used for different purposes.
Electrorefining is used to purify metals through electrolysis, such as copper refining.
Electrowinning is used to extract metals from their ores through electrolysis, such as zinc production.
Electroplating is used to coat a metal object with a thin layer of another metal, such as gold plating on jewelry.

Wire drawing at room temperature is cold working for both steel and tin rods.
Wire drawing involves pulling a metal rod through a die to reduce its diameter.
Cold working is a process where the metal is deformed at room temperature.
Hot working is a process where the metal is deformed at high temperatures.
Steel and tin rods can be cold worked at room temperature through wire drawing.
Hot working is typically done at high t...
