| 1 | Effect of heat treatment on LPSO morphology and mechanical properties of Mg-Zn-Y-Gd alloys显示文摘The mechanical properties and microstructure were investigated under different Zn content and heat treatment conditions in a Mg-Zn-YGd cast alloy.A part of the long period stacking order(LPSO)phases transformed to W-M^ZnaRE?phases with an increase in Zn content from 0.9 at.%to 1.8 at.%,and the ultimate tensile strength(UTS)increased from 229 MPa to 248 MPa.With solution treatment at 480°C,the content of the LPSO phase and strength sharply decreased in the Mg-1.8Zn-0.8Y-0.8Gd alloy,whereas this change was not significantly observed in the Mg-0.9Zn-O.8Y-O.8Gd alloy.After solution treatment,the elongation significantly improved and the UTS sharply decreased in both alloys.The lamellar and filminess LPSO phases were observed with aging treatment at 200℃.Moreover,the strengthening efficiency of lamellar and filminess LPSO phases was lower than that of the block LPSO phases.Therefore,the UTS of the T6 state was lower than that of the as-cast alloy. | Hongxin Liao Jonghyun Kim Taekyung Lee Jiangfeng Song Jian Peng Bin Jiang Fusheng Pan | 2020 | Journal of Magnesium and Alloys2020，8，4： | 14 |
| 2 | Tailoring strength-ductility balance of caliber-rolled AZ31 Mg alloy through subsequent annealing显示文摘Recently,multi-pass caliber rolling has been shown to be effective for Mg alloys.This study investigated the effect of subsequent annealing on the mechanical properties of a caliber-rolled AZ31 Mg alloy to modulate the strength-ductility relationship.This annealing gave rise to different trends in mechanical properties depending on the temperature regime.Low-temperature annealing(T≤473 K)exhibited a typical trade-off relationship,where an increase in annealing temperature resulted in increased ductility but decreased strength and hardness.Such a heat treatment did not degrade the high strength-ductility balance of the caliber-rolled alloy,suggesting that the mechanical properties could be tailored for different potential applications.In contrast,high-temperature annealing(T>473 K)caused a simultaneous deterioration in strength,hardness,and ductility with increasing annealing temperature.These differences are discussed in terms of the varying microstructural features under the different investigated annealing regimes. | Taein Kong Byung Je Kwak Jonghyun Kim Jeong Hun Lee Sung Hyuk Park Ji Hoon Kim Young Hoon Moon Hyun Sik Yoon Taekyung Lee | 2020 | Journal of Magnesium and Alloys2020，8，1： | 10 |

| 5 | Uniaxially crumpled graphene as a platform for guided myotube formation显示文摘Graphene,owing to its inherent chemical inertness,biocompatibility,and mechanical flexibility,has great potential in guiding cell behaviors such as adhesion and differentiation.However,due to the two-dimensional(2D)nature of graphene,the microfabrication of graphene into micro/nanoscale patterns has been widely adopted for guiding cellular assembly.In this study,we report crumpled graphene,i.e.,monolithically defined graphene with a nanoscale wavy surface texture,as a tissue engineering platform that can efficiently promote aligned C2C12 mouse myoblast cell differentiation.We imparted out-of-plane,nanoscale crumpled morphologies to flat graphene via compressive straininduced deformation.When C2C12 mouse myoblast cells were seeded on the uniaxially crumpled graphene,not only were the alignment and elongation promoted at a single-cell level but also the differentiation and maturation of myotubes were enhanced compared to that on flat graphene.These results demonstrate the utility of the crumpled graphene platform for tissue engineering and regenerative medicine for skeletal muscle tissues. | Junghoon Kim Juyoung Leem Hong Nam Kim Pilgyu Kang Jonghyun Choi Md Farhadul Haque Daeshik Kang SungWoo Nam | 2019 | Microsystems & Nanoengineering2019，5，1： | 2 |
