Material Science Tuition Online for Engineering Students
Materials Science and Engineering for degree students: bonding and crystal structures, defects, mechanical properties, phase diagrams, heat treatment and the main classes of materials.
Founder & Head of School, Afterkelas
Afterkelas tutors Material Science online for university and diploma engineering students. Tutors run live classes, 1-to-1 or in small groups, on how structure explains properties, phase diagrams and the calculations your course examines.
What a first Material Science course covers
The core topics of a first university course in materials science and engineering. Each university sets its own order and depth, so the tutor works from your course outline.
Core topics
14 topics- Atomic structure and bonding
- Crystal structures
- Imperfections in solids
- Diffusion
- Mechanical properties: stress, strain and hardness
- Dislocations and strengthening mechanisms
- Failure: fracture, fatigue and creep
- Phase diagrams, including the iron-carbon system
- Phase transformations and heat treatment
- Metal alloys
- Ceramics
- Polymers
- Composites
- Corrosion and degradation
Structure explains properties
Material Science links what happens at the scale of atoms to how a part behaves. Bonding and crystal structure explain stiffness, dislocations explain why metals bend before they break, and phase diagrams explain what heat treatment does to steel. Once those links are clear, the course reads as one connected story and is easier to revise.
Where marks are lost
Calculations lose marks to units, especially MPa against GPa and millimetres against metres, as the worked problem below shows. Phase diagram questions lose marks to misreading the axes or the lever rule. Explanations lose marks when they name a mechanism, such as solid solution strengthening, without saying how it works.
Lab reports on tensile or hardness tests are assessed as the student's own work; tutors explain the theory and the analysis behind them.
Working from your course outline
Each university sets its own order and depth, so the tutor starts from your course outline, tutorial sheets and past papers, and practises the question types your course examines.
A question, worked through
A stress and strain problem. Checking the stress against the yield strength comes before using Hooke's law.
Question
A steel rod 10 mm in diameter and 2.0 m long carries a tensile load of 15.7 kN. The steel has a Young's modulus of 200 GPa and a yield strength of 250 MPa. Find the stress, check whether the rod yields, and find its elongation.
- Cross-sectional area A = π × (0.005 m)² = 7.85 × 10⁻⁵ m².
- Stress σ = F ÷ A = 15 700 N ÷ 7.85 × 10⁻⁵ m² = 2.00 × 10⁸ Pa = 200 MPa.
- 200 MPa is below the 250 MPa yield strength, so the rod deforms elastically and Hooke's law applies.
- Strain ε = σ ÷ E = (200 × 10⁶) ÷ (200 × 10⁹) = 1.0 × 10⁻³, so the elongation is 1.0 × 10⁻³ × 2.0 m = 2.0 mm.
Answer Stress 200 MPa, no yielding, and an elongation of 2.0 mm.
Frequently asked questions
Is Material Science mostly memorisation?
Less than it looks. There are terms to learn, but most marks go to explaining why a structure gives a property, reading phase diagrams and doing short calculations, all of which improve with practice.
Do you help with lab reports?
With the theory and the analysis behind them, yes. The report is assessed as your own work, so the tutor does not write any part of it.
When should Material Science tuition start?
Early in the semester, while bonding and crystal structures are taught, since the properties chapters build on them.
How much does Material Science tuition cost?
The fee depends on the format (1-to-1 or a small group), how many classes a week and the tutor, so there is no single figure. Send an academic advisor the university, the course code and the course outline on WhatsApp, and you will get the current packages and a quote, usually within one working day.
