Mass transfer: Diffusion and Fick’s laws, Mass transfer coefficients
Dimensional analysis: Buckingham Pi theorem, Significance of dimensionless numbers
Basic laws of chemical kinetics: First order reactions, reaction rate constant, Arrhenius relation, heterogeneous reactions, oxidation kinetics
Electrochemical kinetics: Polarization

As per the GATE Syllabus 2022 of Metallurgical Engineering, the subject section of Metallurgical Engineering (MT) accounts for 85 marks in the Question paper.

The GATE Metallurgy Syllabus constitutes seven sections: Engineering Mathematics, Metallurgical Thermodynamics, Transport Phenomena and Rate Processes, Mineral Processing and Extractive Metallurgy Physical Metallurgy, Mechanical Metallurgy and Manufacturing Process.

The important topic of the Mineral Processing and Extractive Metallurgy section are – 
Comminution techniques, Size classification, Flotation, Gravity and other methods of mineral beneficiation; Agglomeration: sintering, pelletizing and briquetting
Material and Energy balances in metallurgical processes; Principles and processes for the extraction of non- ferrous metals – aluminum, copper and titanium
Iron and steel making: Material and heat balance in blast furnace; Structure and properties of slags and molten salts – basicity of slags – sulphide and phosphate capacity of slags; Production of metallurgical coke
Other methods of iron making (COREX, MIDRE)
Primary steel making: Basic oxygen furnace, process dynamics, oxidation reactions, electric arc furnace
Secondary steel making: Ladle process – deoxidation, argon stirring, desulphurization, inclusion shape control, principles of degassing methods; Basics of stainless steel manufacturing
Continuous Casting: Fluid flow in the tundish and mould, heat transfer in the mould, segregation, inclusion control

The important topic of the Mechanical Metallurgy section of the GATE Metallurgical Engineering Syllabus 2022 are – 
Strain tensor and stress tensor, Representation by Mohr’s circle, elasticity, stiffness and compliance tensor, Yield criteria, Plastic deformation by slip and twinning
Dislocation theory: Edge, screw and mixed dislocations, source and multiplication of dislocations, stress fields around dislocations; Partial dislocations, dislocation interactions and reactions
Strengthening mechanisms: Work/strain hardening, strengthening due to grain boundaries, solid solution, precipitation and dispersion
Fracture behaviour, Griffith theory, linear elastic fracture mechanics, fracture toughness, fractography, ductile to brittle transition
Fatigue: Cyclic stress strain behaviour – low and high cycle fatigue, crack growth
Mechanisms of high temperature deformation and failure; creep and stress rupture, stress exponent and activation energy

The important topic of the Manufacturing Processes section are – 
Metal casting: Mould design involving feeding, gating and risering, casting practices, casting defects
Hot, warm and cold working of metals: Metal forming – fundamentals of metal forming processes of rolling, forging, extrusion, wire drawing and sheet metal forming, defects in forming
Metal joining: Principles of soldering, brazing and welding, welding metallurgy, defects in welded joints in steels and aluminum alloys
Powder metallurgy: production of powders, compaction and sintering
Non-destructive Testing (NDT): Dye-penetrant, ultrasonic, radiography, eddy current, acoustic emission and magnetic particle inspection methods

es, there will be negative marking in the examination. Negative marking depends on the type and marks of questions. For NAT questions there will be no negative marking but for 1 or 2 marks ½ and 2/3 marks will be deducted respectively for wrong answers. 

GATE Syllabus typically requires at least 6 months to complete, if the candidate studies for at least 3 hours a day. However, GATE Metallurgical Engineering Syllabus can be completed within 2 months if the candidate dedicates a lot of time and effort.
