In this episode, we explore one of the most important concepts in materials science and failure analysis — the Ductile-to-Brittle Transition (DBTT)
In this video, we explore:
- Why temperature changes fracture behavior
-Why some steels become brittle in cold weather
-How alloying and carbon content affect transition temperature
-Why structural steels are kept low in carbon

In this video, we dive into the Introduction to 𝐌𝐢𝐥𝐥𝐞𝐫 𝐈𝐧𝐝𝐢𝐜𝐞𝐬, one of the most important concepts in Material Science and Crystallography.

We clearly explain:
• What Miller indices are
• Miller indices of directions
• Miller indices of planes

In this video, we break down Gibbs Phase Rule, essential phase diagram terminologies, and the different types of phase diagrams you’ll encounter in Materials & Metallurgical Engineering.

What You Will Learn in This Video:

✔️ What is Gibbs Phase Rule and how to use it
✔️ Key phase diagram terminologies (phase, component, degree of freedom, invariant reaction, etc.)

✔️ Types of phase diagrams (binary isomorphous, eutectic, peritectic, etc.)

In this video, we’ll learn how to determine the Atomic Packing Factor (APF) of an BCC crystal structure ; one of the most important concepts in Materials Science and Engineering.

You Will discover:
• The geometry of the BCC crystal structure
• How to determine the atomic radius relation in BCC
• Step-by-step APF calculation with visualization
• Why BCC has a lower APF than FCC

Welcome back to Materials Codex!
In this lesson, we simplify the fundamentals of phase diagrams ; ideal for Materials & Metallurgical Engineering students who want a clear understanding of microstructures and cooling rate.

In this video, you’ll learn:

● What phase diagrams are and why they matter
● How microstructures form during heating and cooling
● How cooling rate affects the final microstructure
● How to interpret phases, boundaries, and critical lines
● Real engineering examples of phase transformations
