Materials Scientist roadmap

Stage 1 of 3 · about 16 weeks

Foundations

Understand how atoms, bonding and crystal structure produce the properties of metals, ceramics and polymers, and do the math and coding to work with data.

1. 1

   Atomic structure, bonding and crystal structure

   Every property you will ever measure, such as strength, conductivity or brittleness, starts with how atoms are bonded and arranged. Metals deform because planes of atoms can slip; ceramics crack because ionic and covalent bonds resist slip. If you understand this, later topics become explanations instead of facts to memorize.

2. 2

   Mechanical properties and the tensile test

   Testing mechanical strength, ductility and failure is a core daily task. The stress-strain curve is the language you will use with engineers and customers.

3. 3

   Phase diagrams and heat treatment basics

   Phase diagrams tell you which phases exist at a given composition and temperature, so they let you predict what happens when you heat, cool or alloy a material. The iron-carbon diagram is behind nearly every steel decision.

4. 4

   Math and data skills: calculus, statistics, Excel, Python

   You will fit curves, model diffusion and judge whether a difference between two samples is real. Python and Excel are on the standard software list for this job, and statistics keeps you from fooling yourself.

5. 5

   Lab safety and scientific record keeping

   Labs involve chemicals, furnaces, high voltage and loads. Good safety and a clean notebook protect you and make your results trustworthy and repeatable.

Then 2 more stages (about 72 weeks in all) with lessons, drills, projects, 6 interview questions with strong answers and free resources.
