Why is the surface of an implant so important?
In biomaterials engineering, it’s easy to fall back on the intuition derived from traditional materials science: since an implant must withstand loads, not corrode, not…

Why Does Metal Break? An Introduction to Failure Analysis
A crack in a metal component is almost never merely a sign of damage. For an engineer, it is a trace of the history of…

GD&T in Practice
In many companies, GD&T (Geometric Dimensioning and Tolerancing) is often treated as a more difficult, more “formal” version of traditional drafting. When people see symbols,…

Designing stainless steel structures
Stainless steel is increasingly used in construction, not only as cladding or architectural details, but also as a fully-fledged load-bearing material. Its advantage is high…

Other non-ferrous metal alloys
Although materials science most often refers to steels and alloys of aluminum and copper, many key technical applications are based on more specialized non-ferrous metal…

Steels and alloys with special properties
Steels and alloys with special properties are designed when the durability of a component is no longer determined solely by classic mechanical parameters, and one…

Alloying elements in iron-carbon alloys
Carbon steel can achieve a very wide range of properties through heat treatment, but in many applications this is still not enough. The introduction of…

Phase equilibrium systems of alloys
In pure metals, the course of transformations is usually easy to grasp: melting and solidification occur at a single, precisely defined temperature, as do some…
