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......

of the two structures under axial loading were analyzed. The results show that absorbed energy under axial loading of tapered thin-walled tube, tube with diaphragms and tube with honeycomb-diaphragm is 73.2, 133.2 and 221.0 kJ, respectively. The use of diaphragms increases the absorbed energy of thin-walled tube by 82.0%, while the common use of honeycomb and diaphragms improves the absorbed energy......
