摘要：
Aluminum alloys offer a great potential for lightweight construction. By application of Tailored Heat Treated Blanks (THTB), the feasibility of complex car parts out of aluminum alloys can be enhanced decisively. To extend the process window for forming of aluminum, a large scale area has to be heat treated. Accordingly, this paper deals with the large scale heat treatment via laser radiation. Thereby, a multi-path heating strategy is developed and discussed. In order to get a sharp transition area, different cooling methods and the influence on the heat distribution is qualified as well. In this context, the temperature and hardness are measured. (C) 2010 Published by Elsevier B.V.
