Characteristic points of roll contact curves of a two-roll module [PDF]
E3S Web of ConferencesCalculation formulas for finding characteristic angles that determine characteristic points of roll contact curves are obtained. It is established that external forces acting on the roll, the angular velocity of the roll, the feed rate of the material ...

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 ...

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

BASED ON THE NUMERICAL SIMULATION OF COLD ROLL-BEATING FORMING RESIDUAL STRESS RESEARCH
Jixie qiangdu, 2019 When the load to be lifted after cold roll-beating forming the residual stress will appear, in order to effectively control its impact on the forming precision, now the relationship between roll-beating depth and the residual stresses were studied ...

Journal of Advanced Mechanical Design, Systems, and ManufacturingThe increasingly demanding service conditions for aviation spiral bevel gears necessitate higher machining accuracy of the tooth surfaces. The conventional constant roll ratio, a critical parameter governing the relative motion between the cradle and the

Elastic Convection in Vibrated Viscoplastic Fluids
, 2006 We observe a new type of behavior in a shear thinning yield stress fluid: freestanding convection rolls driven by vertical oscillation. The convection occurs without the constraint of container boundaries yet the diameter of the rolls is spontaneously ...

Holography for inflation using conformal perturbation theory [PDF]
, 2012 We provide a precise and quantitative holographic description of a class of inflationary slow-roll models. The dual QFT is a deformation of a three-dimensional CFT by a nearly marginal operator, which, in the models we consider, generates an RG flow to a
