Q1. What is TTT DIAGRAM and its use
Ans. 
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...read more

Q2. What is difference between ceramic and steel
Ans. 
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...read more

Q3. What is fatigue and what is creep in materials
Ans. 
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...read more

Q4. What are the different types of Steel making
Ans. 
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,

Q5. Why do we use alloying elements during Steel making and what are their applications
Ans. 
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, ...read more

Q6. What is SN curve ?
Ans. 
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

Q7. What is the composition of pigiron
Ans. 
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...read more

Q8. What is lever rule?
Ans. 
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...read more
