A kutatási téma leírása:
In recent years, as competition in the market intensifies, there has been a growing need to develop and apply new advanced materials. This is particularly valid for the sheet metal forming processes. This need is mainly enhanced by the automotive industry as one of the main target field of sheet metal products. For many years, the application of conventional cold rolled steels dominated the production of automotive part production especially the so-called Body in White elements. However, in the recent decades, the automotive industry faces with very contradictory demands and requirements: better performance with lower consumption and less harmful emissions, more safety and comfort; these are hardly available simultaneously with conventional materials and conventional manufacturing processes. The fulfillment of these often contradictory requirements are the main driving forces in the automotive industry and thus in the material and process developments in sheet metal forming, as well. To meet these manifold requirements the application of light weight construction principles has an important role. To reduce the weight of automobiles and simultaneously assure the increased safety requirements higher strength metallic materials have to be applied. But it is also well-known that by increasing the strength of materials the formability is significantly decreasing: however the formability of automotive parts is regarded as one of the key issue in car manufacturing.
During the recent decades significant developments can be observed in the application of both high strength steels and various light metal alloys. In this respect, among the high strength steels the application of various dual-phase steels, trip steels, while among the light metals the aluminum alloys are the best examples to meet the above requirements. The aim of this research topic is the investigation of different high strength material candidates first of all from the point of formability in sheet metal forming.
The Department of Mechanical Technology of the University of Miskolc has been researching this topic for many years. Currently, international and collaborative research is being carried out on basic and applied research to promote the industrial introduction of these high strength materials with enhanced formability. The main goal of this PhD research is to determine the formability limits of these materials in various technological processes.
Part of the research can be carried out with international and domestic industrial partners of the related project.
