ABSTRACT
This article focuses on iron-carbon alloys, such as steels and cast irons, and their significance in the field of metallurgy. The iron-carbon diagram is presented as an essential tool for understanding the various phase transformations of alloys based on temperature and carbon content. Steels are ferrous alloys suitable for hot shaping, while cast irons are characterized by eutectic solidification. The constituent phases of steels, such as ferrite, cementite, and perlite, are discussed in detail, along with their impact on the mechanical properties of steels. The size of the ferritic grain is also addressed, including factors influencing its formation. Lastly, the phenomenon of aging in steels is explained, highlighting the differences between natural and artificial aging, as well as the preventive measures to be taken.

INTRODUCTION
Iron-carbon alloys, particularly steels and cast irons, play a central role in metallurgy. Understanding the properties and transformations of these alloys is essential for many aspects of materials engineering. In this article, we will explore the main concepts related to iron-carbon alloys, with a focus on steels. We'll start by looking at the iron-carbon diagram, which provides an overview of the phase transformations of alloys as a function of temperature and carbon content. Next, we'll look at the different constituent phases of steels and their implications for mechanical properties. Finally, we look at the phenomenon of steel ageing and the preventive measures that can be taken to counteract this process.
