The book "Technology of heat treatment" by Mikhail Sitkevich is a fascinating and deep immersion in the world of metallurgy and materials science, which will become an indispensable tool for both students and professionals in this field. If you are interested in processes that determine the properties of metals and alloys, or want to learn more about how heat treatment affects the mechanical characteristics of materials, then this book is for you. Known for his scientific work and practical experience in the field of metallurgy, Sitkevich offers readers not only theoretical knowledge, but also practical recommendations that will help to better understand how heat treatment affects the structure and properties of materials. The book covers a wide range of topics, ranging from the basic principles of heat treatment to modern methods and technologies used in industry. It examines processes such as hardening, annealing, normalization and others, as well as their impact on the strength, hardness and plasticity of metals. One of the key themes of the book is the relationship between heat treatment and the microstructure of materials. Sitkevich explains in detail how different processing modes can change the structure of metals at the microscopic level, which in turn affects their performance. Readers will be able to learn how to choose the right heat treatment modes depending on the type of material and the requirements for the final product. The book will be especially useful for students of technical specialties, engineers and specialists in the field of materials science, as well as for anyone interested in modern metalworking technologies. If you are fond of metallurgy, engineering or just want to expand your knowledge of materials, "Technology of heat treatment" will be a real find for you. It will help you not only to master the theoretical foundations, but also to put them into practice, which is especially important in a rapidly changing technological world. The author's style is distinguished by clarity and accessibility, which makes complex scientific concepts understandable even for beginners. Sitkevich skillfully combines scientific data with practical examples, which allows readers to better assimilate the material. His previous works, such as Metallurgy and Metal Processing Technologies and Fundamentals of Materials Science, have also been recognized for their depth and practical focus. The topics raised in the book address not only technical aspects, but also broader issues such as sustainable development and ecology in metallurgy. Sitkevich raises important questions about how modern heat treatment technologies can contribute to reducing the negative impact on the environment and improving production efficiency. This makes the book relevant not only for professionals, but also for all those interested in sustainable development and ecology. Thus, the "Technology of heat treatment" is not just a textbook, but a real encyclopedia of knowledge for anyone who wants to deepen their knowledge in the field of metallurgy and materials science. This book will be your reliable companion in the study of heat treatment and will help you become a true expert in this important field. Do not miss the opportunity to discover a world where science meets practice, and where every process matters.
