The melting point is one of the most consulted properties in the choice of a material, but also one of the most misunderstood. It's often confused with the maximum operating temperature or with softening. Furthermore, different parameters are sometimes compared, such as the melting point of metals...

What is steel made of? The short answer is: iron and carbon. The complete one opens up a whole world. Steel is a metal alloy composed of over 95% iron, but it's the remaining elements that determine its characteristics.
Understanding the composition of steel means understanding why an S355 behaves...

Copper alloys are one of the most versatile groups of materials available to designers: they combine copper’s conductivity and corrosion resistance with mechanical strength and machinability that pure copper could never achieve. There are hundreds of standardised grades, from free-machining brasses...

The tensile test is the most widely used mechanical test in the world for characterising materials. A single test provides the data that every engineer uses on a daily basis: elastic modulus, yield strength, tensile strength and ductility.
In this article, we examine what the tensile test is, how...

The iron-carbon diagram is one of the most important tools in metallurgy and metallic materials design. It is used to understand how steels and cast irons behave as a function of temperature and carbon content.
Understanding the iron-carbon diagram is essential for choosing the correct material,...
