Special Issue Information

Dear Colleagues,

New materials and new processing techniques have been of importance for promoting human society, especially in an era where high-tech industries are becoming a vital measurement of a nation's competitiveness and sustainable development, they also have been the core driving force for vehicle, ship, aerospace and other traditional manufacturing industries.

Hot forming is the latest manufacturing technology, combining the traditional heat treatment technology and the cold stamping technology, which has drawn universal attention from the national industrial policy, industrial circles and academia. It presents broad development prospects and long-term vitality. The numerical simulation method has become an indispensable and important tool for the successful application of hot forming technology in complex industrial products. Nowadays, hot forming is mainly used in the automotive industry, but this technology can be expected to be widely used in other industries, especially in shipbuilding, high-speed train and civil construction. Thus, this Special issue welcomes articles devoted to these industrial fields.

Papers that employ the symmetry or asymmetry concept in their methodologies in the fields of Hot Forming and Numerical Simulation are welcomed. Articles and reviews devoted to the theoretical foundations, associated numerical simulation methods and their applications for the hot forming of metal material are also welcome.  Last but not the least, submissions devoted to different aspects of hot forming and numerical simulation are encouraged.

Please note that all submitted papers must be within the general scope of the Symmetry journal.

The production of ultra-high strength automotive components requires a multi-directional approach. Hot stamping combines both forming and heat treatment processes to obtain a usually martensitic structure of complicated shaped automotive parts. The preparation for production using hot stamping must involve the latest methods of numerical analysis of both temperature changes and forming, which are applied for an increasing range of materials used. In this paper, the current state of knowledge about the basics of hot stamping, used technological lines, and the current state of material used with applied heat treatments and possible coatings have been reviewed. Moreover, the numerical modeling process has been described. The most important aspects of process automation, including the use of digital twins for simulation and optimization of operational kinetics of the robots accomplishing the production process, analysis and minimization of time of production cycles, and searching for weak operational points of the control systems and for real time visualization of operation of complete line, are considered. The digital twins and corresponding numerical models enable the symmetrical design of real production lines. The details of heat treatment profiles with so called tailored zone heat treatment are provided. Hot stamping is a dynamically developing technology as evidenced by the increasing range of materials used, also from the 3rd generation of advanced high strength (AHSS) steels. It starts to combine forming of symmetric or asymmetric elements with more complex heat treatment processes as required for dual phase (DP) stainless steels or the newest generation of high-strength and ductile medium-manganese steels.
