fractured. Key words: 2219 aluminum alloy; tungsten inert gas arc welding; partially melted zone; fracture behavior 1 Introduction Precipitation hardening 2219 aluminum alloy has been widely used in welded cryogenic fuel tanks due to its outstanding mechanical properties over a wide temperature range from -250 °C to 250 °C [1]. Friction stir welding (FSW) of 2219 aluminum alloy is a pioneer method......

the strength and wear resistance of aluminum alloy parts in automotives. Long duration time as well as long pre-sputtering time are required for plasma nitriding of aluminum or its alloys only with the thickness of a few micrometers. New plasma inner nitriding is proposed to realize the fast-rate nitriding of aluminum alloys. Al-6Cu alloy is employed as a targeting material in order to demonstrate......
