Active Disk Building in a local HI-Massive LIRG: The Synergy between Gas, Dust, and Star Formation [PDF]

, 2010
HIZOA J0836-43 is the most HI-massive (M_HI = 7.5x10^10 Msun) galaxy detected in the HIPASS volume and lies optically hidden behind the Milky Way. Markedly different from other extreme HI disks in the local universe, it is a luminous infrared galaxy ...

Warm forming of 7075 aluminum alloys

Procedia Engineering, 2017
Abstract The paper presents forming results of the drawpiece made of T6 temper 7075 aluminum alloy. The development of new, state-of-the-art forming methods by scientific and research centers is mainly driven by increasing demand for lightweight construction materials characterized by superior mechanical properties. As an example, new forming methods
