Heat treatment is a very important basic process in the machinery industry and plays a very important role in improving the quality and extending the service life of mechanical products. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled through heat treatment. Therefore, the heat treatment of steel plays an important role in metal heat treatment.
Today I recommend this book "New Edition of Isothermal Heat Treatment of Steel". The book only provides a general introduction to the traditional common heat treatment processes. It also introduces the main types of isothermal heat treatment processes and the corresponding heat treatment characteristics, process specifications, steps and application effects. A key introduction was made, and the cooling medium in isothermal heat treatment, especially the cooling medium commonly used in actual industrial production, was analyzed and introduced. The mechanical properties obtained by different workpieces after isothermal heat treatment were also introduced in detail. .
As early as 1964, Mr. Liu Yunxu summarized his theory and experience in heat treatment teaching, scientific research and production work, and combined the types, characteristics and effects of foreign advanced isothermal heat treatment processes with the actual industrial conditions of our country at that time, and compiled Published the book "Isothermal Heat Treatment of Steel". This book was widely praised by readers after its publication and was reprinted many times in 1966 and 1973. It played a positive role in promoting the development of my country's steel isothermal heat treatment industry.
In recent years, due to the emergence of some new materials and new technologies, as well as the in-depth technical exchanges with foreign countries, my country's steel heat treatment technology has made great progress. In order to better promote the research, development and application of advanced isothermal heat treatment technology in my country and promote the cultivation of innovative talents in China's heat treatment industry, Ms. Liu Cheng summarized the development and application practice of steel isothermal heat treatment technology at home and abroad for more than 50 years. , based on the original "Isothermal Heat Treatment of Steel", a "New Edition of Heat Treatment of Steel" was compiled.
"New Edition of Steel Heat Treatment" is rich in content and combines theory and practice. It introduces the detailed steps of the isothermal heat treatment process of various steel types and mechanical components commonly used in the machinery industry, and adds the development results of innovative isothermal heat treatments, such as , austempering of Aubert ductile iron, super bainite low-temperature isothermal quenching, Q-P, Q-P-A and Q-P-T heat treatment, etc., and also introduced the problems existing in the application of the new process in industrial practice. Therefore, this book is based on the principle of providing effective services for actual industrial production, with the goal of expanding innovative theories for those engaged in the heat treatment industry, and with the goal of cultivating the professionalism of young heat treatment successors. Through a large number of process examples and diagrams, this book is intended for the general public Readers are provided with a reading and learning experience that is rich in knowledge, has a broad vision, is forward-looking, and integrates theory and practice. I believe this book will bring new impetus to the steel heat treatment industry across the country.
