Available in PDF, EPUB and Kindle. Book excerpt: The world of steel is amazingly diverse and so complex that it is not easy to keep track of in practice. In the form of portraits of selected steels and steel groups, this world of steel is to be brought closer to the reader; compact, understandable, informative, structured with examples from practice and suitable for reference. Hot work tool steels are a group of alloyed steels with high hot strength suitable for tools. These can withstand surface temperatures of more than 600 °C in use. For this purpose, they are optimally adapted to the most diverse requirements, especially for tools used in hot forming and die casting. Important are the chemical compositions, methods of production and processing as well as their properties or the material data of hot work tool steels, which are briefly and clearly presented in this book. The contents · The history of hot work tool steels · Designations, chemical compositions, grades, microstructure and properties · Production (melting and powder metallurgy), heat and surface treatments The target groups Trainees in metal professions Students, practitioners, engineers in steel production, forming and production technology, in steel, metal and tool construction and in the steel trade

This book was released on 2018-07-15 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is study on tool steel pacification and heat-treatment for all type of wear resistance steel and specially our D3 steel. Supported with value review. This research “theoretical and experimental” in Effect of Heat-treatment “hardening temperature, tempering temperature, and cooling rate“ in the Mechanical property “Hardness”, and Microstructure transformation on Tool Steel, all type of wear resistance steel, and specially D3 steel. The research study heat-treatment for two pieces of D3 die steel "Working at cone pulleys for nail manufacture" to modify there mechanical properties. The classification its type, properties and set on condition effect on it was discussed. Two set of experiments were done one to determine the effect of austenitization temperature and tempering temperature on the mechanical properties "hardness" and another "the basic one" to discuses improving its mechanical properties from view of microstructure transformations "type, amount, and properties" for each heat-treatment stage. This study was APPROVED as my BS graduate project from Metallurgy Engineering Collage, Cairo University 2001, and published after addition in experimental review at 2018.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tool steels serve a large range of applications in hot and coId working of metals as well as injection moulding of plastics or light alloys. Ledeburitic tool steels are mainly used in coId working operation where an extremely high wear resistance is requested. Therefore, these steels present coarse and very hard primary alloyed (Iedeburitic) carbides. Non-ledeburitic tool steels have a still wider range of use in hot working and especially in warm or hot injection moulding. The carbides in these steels are very fine secondary microcarbides. For these two categories of steel, the industrial need is to optimise the compromise between high mechanical resistance levels and better response to both static and cyclic loadings. For ledeburitic tool steels, numerical modelling of realistic microstructures is able to calculate the stress distributions and concentrations resulting from the heterogeneity in terms of carbide size, shape and distribution, as well as the topological characteristics of the fracture surface. The report outlines the development of analytical and numerical models leading to predict the influence of microstructure on fracture toughness of ledeburitic tool steels. This prediction is compared to experimental results on forged bars from ingots and HIPed powder metallurgy products. Although the comparison of sensitive parameters between experimental, analytical and numerical results is not always consistent, the agreement existing on the favourable role of net-like structure of primary carbides and on the increase of toughness with the fracture surface roughness offers the possibility to use numerical modelling to find the optimal microstructure.

Available in PDF, EPUB and Kindle. Book excerpt: The properties of steels depend critically on their microstructure. By examining the mechanical properties of steels in conjunction with microstructure, the first edition gave a clear description of the development and behavior of these materials - the very foundation of their widespread use. This new edition more explicitly links this theory with applications while retaining the style and purpose of its predecessor.

This book was released on 2022-03-25 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances are continuously being made in applying the coatings and surface treatments by different techniques to reduce the damages from tribology. Engineers need more detailed information to compare the capability of each coating process in wear resistant and lubrication applications. It is also important to focus on the concepts of tribology in various applications such as the manufacturing process, bio implants, machine elements, and corrosive environments. The need for a comprehensive resource addressing these findings in order to improve wear resistance is unavoidable. The Handbook of Research on Tribology in Coatings and Surface Treatment evaluates the latest advances the fabrication of wear-resistant and lubricant coatings by different techniques and investigates wear-resistant coatings and surface treatments in various applications such as the automobile industry. Covering a wide range of topics such as lubricant coatings and wearable electronic devices, it is ideal for engineers, industry professionals, researchers, academicians, scholars, practitioners, instructors, and students.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High-chromium martensitic steels are one of the basic creep-resisting construction materials used for the modernization of old and the construction of new power units. During the service under creep conditions, the metastable microstructure of martensitic steels undergoes gradual degradation. The rate of degradation mostly depends on the operating temperature, but it is also affected by stresses. The changes in the microstructure of martensitic steels have an influence on the decrease in their mechanical properties, including creep resistance. The knowledge and description of the changes in the microstructure of steels working under creep conditions allow extending the time of safe operation of the elements of power systems. The paper presents and describes the main mechanisms of degradation of 9-12%Cr martensitic steels on the basis of the independent studies and literature data.
