| 1 | Metal Fabrication by Additive Manufacturing Using Laser and Electron Beam Melting Technologies显示文摘Selective laser melting (SLM) and electron beam melting (EBM) are relatively new rapid, additive manufac- turing technologies which can allow for the fabrication of complex, multi-functional metal or alloy monoliths by CAD-directed, selective melting of precursor powder beds. By altering the beam parameters and scan strategies, new and unusual, even non-equilibrium microstructures can be produced; including controlled microstructural architectures which ideally extend the contemporary materials science and engineering paradigm relating structure-properties-processing-performance. In this study, comparative examples for SLM and EBM fabricated components from pre-alloyed, atomized precursor powders are presented. These include Cu, Ti–6Al–4V, alloy 625 (a Ni-base superalloy), a Co-base superalloy, and 17-4 PH stainless steel. These systems are characterized by optical metallography, scanning and transmission electron microscopy, and X-ray diffraction. | Lawrence E. Murr Sara M. Gaytan Diana A.

| 2 | Short lessons in basic life support improve self-assurance in performing cardiopulmonary resuscitation显示文摘BACKGROUND:There are several reasons why resuscitation measures may lead to inferior results:difficulties in team building,delayed realization of the emergency and interruption of chest compression.This study investigated the outcome of a new form of in-hospital cardiopulmonary resuscitation(CPR) training with special focus on changes in self-assurance of potential helpers when faced with emergency situations.METHODS:Following a 12-month period of CPR training,questionnaires were distributed to participants and non-participants.Those non-participants who intended to undergo the training at a later date served as control group.RESULTS:The study showed that participants experienced a significant improvement in selfassurance,compared with their remembered self-assurance before the training.Their self-assurance also was significantly greater than that of the control group of non-participants.CONCLUSION:Short lessons in CPR have an impact on the self-assurance of medical and non-medical personnel. | Mario Kobras Sascha Langewand Christina Murr Christiane Neu Jeannette Schmid | 2016 | World Journal of Emergency Medicine2016,7,4: | 7 |

| 4 | Nanoscale deformation of multiaxially forged ultrafine-grained Mg-2Zn-2Gd alloy with high strength-high ductility combination and comparison with the coarse-grained counterpart显示文摘Cold processing of magnesium(Mg) alloys is a challenge because Mg has a hexagonal close-packed(HCP)lattice with limited slip systems, which makes it difficult to plastically deform at low temperature. To address this challenge, a combination of annealing of as-cast alloy and multi-axial forging was adopted to obtain isotropic ultrafine-grained(UFG) structure in a lean Mg-2Zn-2Gd alloy with high strength(yield strength: ~227 MPa)-high ductility(% elongation: ~30%) combination. This combination of strength and ductility is excellent for the lean alloy, enabling an understanding of deformation processes in a formable high strength Mg-rare earth alloy. The nanoscale deformation behavior was studied via nanoindentation and electron microscopy, and the behavior was compared with its low strength(yield strength: ~46 MPa)-low ductility(% elongation: ~7%) coarse-grained(CG) counterpart. In the UFG alloy, extensive dislocation slip was an active deformation mechanism, while in the CG alloy, mechanical twinning occurred.The differences in the deformation mechanisms of UFG and CG alloys were reflected in the discrete burst in the load-displacement plots. The deformation of Mg-2Zn-2Gd alloys was significantly influenced by the grain structure, such that there was change in the deformation mechanism from dislocation slip(non-basal slip) to nanoscale twins in the CG structure. The high plasticity of UFG Mg alloy involved high dislocation activity and change in activation volume. | K. Li V.S.Y.Injeti P. Trivedi L.E. Murr R.D.K.
