ABSTRACT Attracting talent to public administration is a highly relevant issue of practical concern and scholarly debate. Building on unique survey data of 424 individuals who switched jobs to join public administration, this study explores public employer attractiveness in a multi‐incentive setting, accounting for the experiences of a less explored ...

Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Thermal Effect Mechanism and Surface Topography of the Micro-EDM Workpiece [PDF]
微细电火花加工具有可以非接触加工、三维加工能力以及设备简单、可实施性强、加工性能与材料硬度强度无关等优点。这种方法能加工处理的材料非常广泛,不仅可以加工各种性能优良的金属、合金,还可以加工陶瓷、硅等半导体材料。因此,微细电火花加工在复杂微小零件的制作中有着独特的优越性,也得到了广泛的应用。目前,微细电火花加工的理论研究和工艺研究还存在很多问题,尤其在蚀除过程中,现在普遍采用普通电火花的加工机理来说明。微细电火花加工具有放电时间短、放电通道半径小及能量密度高等特点,所以其放电过程与普通电火花明显不同。因此,

Ti49.3Ni50.7 shape memory alloy is highly biocompatible but difficult to machine due to its complex thermo‐mechanical behavior. An enhanced Wire EDM process was developed using a Taguchi L18 design, GRA, and Random Forest with Bayesian optimization. The optimized parameters achieved a surface roughness of 1.298 μm and a material removal rate of 2.537 ...

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...

The densification process of Li6PS5Cl powders with varying particles size distributions reveals differences in smaller and larger distributions. Higher strain is revealed for the smaller particle size distribution from X‐ray diffraction. Discrete element method simulations uncover that the reason for the higher strain is not the particle size itself ...

Ta‐Mo‐Cr‐Ti‐Al refractory high‐entropy alloys show atmosphere‐dependent oxidation performance based on Cr:Ti ratios. Cr‐rich compositions excel in dry oxygen through continuous chromia formation, while Ti‐rich alloys perform better in humid conditions due to reduced chromium volatilization and hydrogen uptake effects.
