This work, written with clarity and accuracy, will be a real discovery for students, graduate students and anyone who is interested in materials and their behavior under the influence of various forces. Sergei Ivanovich Gubkin, a well-known Russian scientist and author of many works in the field of materials science, offers the reader a unique look at the processes occurring in metallic substances. In his book, he examines the theoretical basis of metal flow by analyzing how various factors, such as temperature, pressure, and structure, affect their behavior. It’s not just a textbook — it’s a veritable encyclopedia of knowledge in which every page is filled with valuable data and examples. The book will be of interest not only to specialists in the field of materials science, but also to those who are fond of physics, engineering and even the history of science. If you are a student studying physics or engineering, or just like to understand how the world around you is arranged, the Theory of the Flow of Metallic Matter will become an indispensable source of information for you. It will also attract the attention of professionals working in the field of mechanical engineering, metallurgy and other related disciplines. Gubkin raises many topical topics related to the behavior of metals. It explores how different operating conditions can change the properties of materials, and how these changes can be taken into account when developing new technologies. This book not only enriches the reader’s knowledge, but also makes one think about how important it is to take into account the physical properties of materials in modern production and scientific research. The author's style is distinguished by clarity and accessibility, which makes complex concepts understandable to a wide audience. Gubkin uses many examples from practice, which allows the reader to better absorb the material and see its application in real life. His previous works, such as Metals and Their Properties and Fundamentals of Materials Science, have also been recognized for their scientific rigor and practical relevance.[citation needed] The book “The Theory of the Flow of Metal Material” is not just a set of theoretical calculations, but a whole world in which physics and engineering are intertwined, creating new opportunities for science and technology.
