Advanced Engineering Materials, EarlyView.Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories
Advanced Engineering Materials, EarlyView.Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...

Advanced Engineering Materials, EarlyView.A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Fiber-reinforced geopolymer composites: A review
Cement & Concrete Composites, 2020 There is a burgeoning interest in the development of geopolymers as sustainable construction materials and incombustible inorganic polymers. However, geopolymers show quasi-brittle behavior.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Assessment of Depth Contact Endurance of Surface-Hardened Gears
Механика машин, механизмов и материаловThe main factors determining the performance of highly stressed surface-hardened gears of transmissions of energy-consuming machines are the parameters of a hardened layer, especially the behavior of hardness distribution over its thickness. The existing

Dielectric behaviour of hardened cementitious materials
Advances in Cement Research, 1997 The dielectric behaviour of mature Portland cement pastes prepared at water/cement ratios 0·3 to 0·7, and pastes containing various percentages of silica fume at water/cement ratio 0·3 was investigated over a frequency range of 1 MHz to 1·5 GHz. The value of dielectric constant is water content dependent.
