Dynamic fracture of Ti-6Al-4V alloy in Taylor impact test REN Yu1, TAN Cheng-wen1, 2, ZHANG Jing1, WANG Fu-chi1 1. School of Materials Science and Engineering, Beijing Institute of Technology... February 2010; accepted 19 April 2010 Abstract: The dynamic fracture behaviors of Ti-6Al-4V alloy at high strain rate loading were investigated systemically through Taylor impact test, over the range......
types of impact were examined through experiments. The impact energy of a striker was applied on the fixed aluminum foam having a thickness of 25 mm while increasing its impact by 2 J at each strike from 6 J to 16 J. The results show that the impact energies from 6 J to 12 J could not penetrate aluminum foam. However, the aluminum foam applied with the impact energy of 12 J incurred severe damages......

Little research has been......
Comparison of Impact Properties for Carbon and Low Alloy SteelsO.H.Ibrahim摘 要:The impact properties of hot rolled carbon steel(used for the manufacture... ferrite/pearlite phases,while that of the quenched and tempered low alloy steel contained bainite structure.Impact properties were determined for both steels by instrumented impact testing......
Trans. Nonferrous Met. Soc. China 22(2012) 2334-2342 Effect of microstructure on impact toughness of magnesium alloys HUANG Zheng-hua, QI Wen-jun, XU Jing Guangzhou Research Institute of Nonferrous... investigated. Meanwhile, the impact toughness was tested and then the relationship was discussed. The results show that as-cast microstructure is refined gradually with increasing the RE content. Mg-Zn-RE new......
