Development of the technology for press-forming of energy-absorbing elements made of 7075 aluminum alloy

Autor: K. Jaśkiewicz, Mateusz Skwarski, Paweł Kaczyński

Publikováno v: Journal of Manufacturing Processes. 50:676-683

The following paper presents the influence of the cooling rate of 7075 aluminum alloys on the strength properties and microstructure of press-formed products. The material minimum cooling rate of 30 °C/s, allowing to obtain a supersaturated solid so
