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 ...

Results in Physics, 2018 Quality defects of fracture surface are easily produced in the fracture splitting process of connecting rod. At present, the resulting mechanism of this type of defect is lacking in evidence and there is no effective control method.

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

Aircraft body-axis rotation measurement system [PDF]
, 1983 A two gyro four gimbal attitude sensing system having gimbal lock avoidance is provided with continuous azimuth information, rather than roll information, relative to the magnetic cardinal headings while in near vertical attitudes to allow recovery from ...

Agenda Control in the Bundestag, 1980-2002 [PDF]
, 2006 We find strong evidence of monopoly legislative agenda control by government parties in the Bundestag. First, the government parties have near-zero roll rates, while the opposition parties are often rolled over half the time.

Constant-roll inflation: confrontation with recent observational data
, 2017 The previously proposed class of phenomenological inflationary models in which the assumption of inflaton slow-roll is replaced by the more general, constant-roll condition is compared with the most recent cosmological observational data, mainly the ...

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...
