Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Environmental changes during secondary succession in a tropical dry forest in Mexico
, 2011 Vegetation and environment change mutually during secondary succession, yet the idiosyncrasies of the vegetation effect on the understorey environment are poorly understood. To test whether the successional understorey environment changes predictably and

Operation and recovery of a seasonally-loaded UK waste stabilisation pond system [PDF]
, 2013 An intermittent discharge waste stabilisation pond system was trialled for treatment of a seasonal wastewater load from a campsite. The system showed rapid acclimatisation to incoming load, with chlorophyll-a exceeding 700 mg l?1 within 2 weeks and ...

Experimental characterization of a reversible heat pump for hybrid and electric vehicles
Advances in Mechanical Engineering, 2019 The most performant system for heating in electric and hybrid vehicles is the heat pump. This study proposes a heating system with a reversible heat pump, which works as a conventional air conditioning system in cooling mode and in heating mode it uses a
