Fuels are substances that release heat energy during combustion due to the oxidation process that occurs. In order for a substance to serve as fuel, it is important that it has a high calorific value, which is most affected by the carbon content. Sulfur has a very small effect on this characteristic of the fuel but is considered as a negative compo...

Formability is the ability of a material to deform without fracturing, and the assessment of this property depends on various factors such as temperature, deformation speed, and stress state. There are two main approaches to determining formability: one is based on testing different materials under controlled stress conditions, and the other on dev...
