Realizing high work hardening and thus elevated strength–ductility synergy are prerequisites for the practical usage of body-centered-cubic high entropy alloys(BCC-HEAs).In this study,we report a novel dynamic strengthening mechanism,martensitic twinning transformation mechanism in a metastable refractory element-based BCC-HEA(TiZrHf)Ta(at.%)that can profoundly enhance the work hardening capability,leading to a large uniform ductility and high strength *** from conventional transformation induced plasticity(TRIP)and twinning induced plasticity(TWIP)strengthening mechanisms,the martensitic twinning transformation strengthening mechanism combines the best characteristics of both TRIP and TWIP strengthening mechanisms,which greatly alleviates the strengthductility trade-off that ubiquitously observed in BCC structural *** characterization,carried out using X-ray diffraction(XRD)and electron back-scatter diffraction(EBSD)shows that,upon straining,α”(orthorhombic)martensite transformation,self-accommodation(SA)α”twinning and mechanicalα”twinning were activated *** electron microscopy(TEM)analyses reveal that continuous twinning activation is inherited from nucleating mechanical{351}type I twins within SA“{351}”typeⅡtwinnedα”variants on{351}twinning plane by twinning transformation through simple shear,thereby accommodating the excessive plastic strain through the twinning shear while concurrently refining the grain ***,consistent high work hardening rates of 2–12.5 GPa were achieved during the entire plastic deformation,leading to a high tensile strength of 1.3 GPa and uniform elongation of 24%.Alloy development guidelines for activating such martensitic twinning transformation strengthening mechanism were proposed,which could be important in developing new BCC-HEAs with optimal mechanical performance.

马里兰州塞西尔县的Dominion电气公司的野猫生存区设施（WPGF）将需要使用宾夕法尼亚州兰开斯特县Conowingo水库的水源。野猫活动点原水供应项目（WPRWS）包括建设苏格兰汉纳河畔的新泵房，竖井进水井和运输管道，将从水库抽水供WPGF使用。采用微型隧道铺设供应／返回管道，管材为直径830R，60in的T-7Pemlalok钢套管，施工由Bradshaw建筑公司于2016年6月完成，与其对应的项目六年前在河对岸完成施工。Bradshaw还建造了永久的54ft深的竖井，由于空间限制，开始需要296in衬板支撑，并在开挖完成后进行喷浆衬砌．微型隧道施工的地层条件复杂，从竖井至诺福克南部铁路下方为岩层，从水库底下开始转变为非常柔软的细粒冲积层。采用微型隧道法的主要原因是水体下的非常软的淤泥和粘土，是浮选壳体，设计人员需要改装套管以对付那些浮力。本文将讨论承包商建设竖井和微隧道作业的规划和施工计划，制造商对T-7Permalok钢管套管所需特殊规定，以及各个方面如何协调共同成功完成一个项目。
