Here's a detailed feature on "Tratamientos Térmicos de los Aceros" (Thermal Treatments of Steels) by José Apraiz Barreiro:
Introduction
Thermal treatments are a crucial process in the production of steel, as they can significantly impact the microstructure and properties of the material. José Apraiz Barreiro, a renowned expert in the field, has written extensively on the topic of thermal treatments of steels. In his work, "Tratamientos Térmicos de los Aceros," he provides an in-depth analysis of the various thermal treatment processes used to modify the properties of steels.
Types of Thermal Treatments
Apraiz Barreiro identifies several types of thermal treatments commonly used in the steel industry:
Austenitization and Quenching
Apraiz Barreiro discusses the importance of austenitization, a process in which the steel is heated to a temperature above the critical temperature (Ac3), causing the microstructure to transform into austenite. Quenching, or rapid cooling, is then used to transform the austenite into martensite, a hard and brittle microstructure.
Microstructural Changes
The author explains how thermal treatments can modify the microstructure of steels, leading to changes in their properties. The main microstructural changes that occur during thermal treatments are: Tratamientos Térmicos de los Aceros by José Apraiz

The book " Tratamientos Térmicos de los Aceros " by José Apraiz Barreiro
is a fundamental technical reference for metallurgy and industrial engineering. It covers the principles and practical applications of heating and cooling processes used to alter the internal structure of steel to improve mechanical properties like hardness and toughness. Core Content and Topics
Based on various editions, including the 700+ page 10th edition, the book typically includes:
Fundamental Principles: Introduction to phase transformations and the Iron-Carbon (Fe-C) diagram.
Critical Temperatures: Detailed study of the transformation points essential for effective heat treatment.
Microscopic Constituents: Analysis of austenite, ferrite, pearlite, martensite, and bainite.
Cooling Curves: Use of TTT (Time-Temperature-Transformation) diagrams for both isothermal and continuous cooling. Key Treatment Types:
Annealing (Recocido): Softening the steel for better machinability and removing internal stresses.
Normalizing (Normalizado): Refining the grain structure to a standard state.
Hardening (Temple): Increasing hardness through rapid cooling; includes study of hardenability (templabilidad) and the Jominy test. For each defect
Tempering (Revenido): Reducing the brittleness of hardened steel while maintaining strength.
Thermochemical Treatments: Surface hardening techniques such as Nitriding (Nitruración) and carburizing. Where to Find the PDF and Physical Copies

Instead of abstract curves, Apraiz provides real data for cooling rates in:
This data allows engineers to select quenchants without guesswork.
The most celebrated section is on defects. Apraiz Barreiro includes macros and micrographs showing:
For each defect, he prescribes cause and remedy—a lifesaver for heat treat shop floor supervisors.
Before diving into the technical content, it is essential to understand the author. Jose Apraiz Barreiro was a Spanish industrial engineer and a pioneering educator in the field of metallography. His work emerged during a critical period when the Spanish steel industry was modernizing in the mid-20th century.
Unlike purely academic authors, Apraiz Barreiro had extensive hands-on experience in foundries and heat treatment plants. This practical background allowed him to write a book that balances theoretical rigor with real-world applicability. He understood that a metallurgist doesn’t just need phase diagrams—they need to know how to avoid warping a crankshaft during quenching.
While many textbooks show the Fe-C diagram, Apraiz Barreiro takes time to explain why each line exists. He relates the A1, A3, and Acm lines directly to industrial hardening practices. For instance, he emphasizes the risk of overheating hypoeutectoid steels—a mistake that leads to grain coarsening.
