| 1 | Enhancing strength and ductility of AlSi10Mg fabricated by selective laser melting by TiB_(2)nanoparticles显示文摘In the metallic components fabricated by the emerging selective laser melting(SLM)technology,most strategies used for strengthening the materials sacrifice the ductility,leading to the so-called strengthductility trade-off.In the present study,we report that the strength and ductility of materials can be enhanced simultaneously by introducing nanoparticles,which can break the trade-off of the metallic materials.In the case of in-situ nano-TiB_(2)decorated AlSi10Mg composites,the introduced nanoparticles lead to columnar-to-equiaxed transition,grain refinement and texture elimination.With increasing content of nanoparticles,the strength increases continually.Significantly,the ductility first increases and then decreases.Our results show that the ductility is controlled by the competition between the crack-induced catastrophic fracture and ductile fracture associated with dislocation activities.The first increase of ductility is mainly attributed to the suppression of crack-induced catastrophic fracture when TiB_(2)nanoparticles present.With the further increase of TiB_(2)nanoparticles,the subsequent decrease of ductility is mainly controlled by dislocation activities.Thus,the materials will exhibit the optimum strength and ductility combination in a certain range of TiB_(2)nanoparticles.This study clarifies the physical mechanism controlling ductility for nano-TiB_(2)decorated Al Si10Mg composites,which provides the insights for the design of structural materials. | Y.K.Xiao H.Chen Z.Y.Bian T.T.Sun H.Ding Q.Yang Y.Wu Q.Lian Z.Chen H.W.Wang | 2022 | Journal of Materials Science & Technology2022，，14： | 2 |

| 6 | Resonant Scattering of 22Na+p by Thick-Target Inverse Kinematic Method显示文摘22 Na is one of the most important yet debatable cosmic γ-ray emitters. The relative short half-life of 22 Na (T1/2=2.6 a) and the delayed 1.275 MeV γ-ray indicate that the 22Na may be a very sensitive probe to the nova outburst, especially for the nearby ONe novae from the Sun. | WANG You-bao JIN Sun-jun SU Jun YAN Sheng-quan LI Yun-ju GUO Bing LI Zhi-hong BAI Xi-xiang LIU Wei-ping H.Yamaguchi S.Kubono D.Kahl J.Hu H.S.Jung J.Y.Moon T.Teranishi H.W.Wang H.Ishiyama H.Iwasa H.Komatsubara | 2012 | Annual Report of China Institute of Atomic Energy2012，，1： | 0 |
| 7 | 用逆运动学厚靶方法研究22Na+p共振散射显示文摘正22Na是最重要但又有争议的宇宙γ射线发射体之一,其相对较短的衰变寿命(T1/2=2.6a)及其缓发的1.275MeVγ射线,使其有可能成为太阳系附近ONe新星爆发的灵敏探针。在新星形成过程中随温度提高有两种模式,即20Ne(p,γ)21Na(β+)21Ne(p,γ)2Na或20Ne(p,γ)21Na(p,γ)22Mg(β+)22Na可生成22Na, | 王友宝 金孙均 苏俊 颜胜权 李云居 郭冰 李志宏 白希祥 柳卫平 H.Yamaguchi S.Kubono D.Kahl J.Hu H.S.Jung J.Y.Moon T.Teranishi H.W.Wang H.Ishiyama N.Iwasa H.Komatsubara | 2012 | 中国原子能科学研究院年报2012，，1： | 0 |
