Fundamentals & Basics
The Intensive Training Module A constitutes the foundation of all following PHS-related trainings and coachings. It therefore must be successfully completed before continuing on to any other training. Participants are typically engineers, technicians, and foremen in the fields of production and quality assurance, as well as maintenance, production planning and control, marketing and sales, and tool design and manufacturing.
As indicated in the figure, the training contents are divided into 3 topical units.
Contents. An overview of the historical development, the current state-of-the-art, as well as numerous examples of PHS applications will be given. Market developments are indicated. The expectations of different OEMs for future PHS application will be explained.
Aims & Targets. Participants will obtain a comprehensive overview of more than four decades of development in PHS technology, ultimately putting the training group on the same page regarding their perception of technological contents and market expectations.
UnitA1:Fundamentals of Heat Treatment and Hot Forming
Contents. The fundamentals of heat treatments for steel and steel forming at high temperatures as well as selected aspects of press hardening applications will be provided in a combination of seminars and practical experience. This will include lab internships, which deal with the central mechanisms of plastic deformation. In particular, these seminars focus on the basic influence of heat on phase transformations, microstructures, and mechanical properties, as well as on the forming behavior, formability and flow stress. Similarly, questions about high temperature tribology will be answered.
Aims & Targets. Using their acquired knowledge and skills, participants will be able to set defined properties for selected steels that are suitable for heat treatment processes. They will further understand the influence of thermal processing on forming conditions. Fundamental principles of heat treatment of steel will be elaborated.
UnitA2:Basics of Industrial Hot Stamping
Contents. A major challenge in press hardening is processing safely and reliably, while efficiently combining heat treatment and forming. The different process variations of the press hardening process will be explained in detail in the seminar from a process-oriented, technological point of view as well as from a material-oriented, technological point of view. In the presentations, the individual properties of different material processing systems will be taken into account. The creation of functionally graded, press hardened components using strategies that are time-dependent and have locally variable temperature controls is comprehensively explained. The influence of different material processing systems when in contact with selected tool steels and the influence of coatings on the tribological system design will also be of interest.
This knowledge will be reinforced by practical work experience in the laboratory by performing extensive press hardening trials. Questions which concern the selection of appropriate methods for thermal process control will also be addressed.
Aims & Targets. The participants will gain the ability to reliably handle and utilize the latest material processing systems, which are essential for press hardening body panels under mass production conditions. Based on their acquired knowledge, participants will be capable of making appropriate process parameter choices for different material systems as well as for functionally graded PHS parts in terms of adjusting defined mass and/or property gradation patterns. Methodological skills on through-process monitoring of interdependent process and part characteristics will be available.
