Constitutive model and dynamic deformation behavior of 800 MPa grade cold-rolled dual phase steel
工程科学学报, 2016 The Hopkinson experiment system was used to do the dynamic tensile experiment of 800 MPa grade cold rolled dual phase steel (DP800). The strain rate was determined as 500, 1000 and 2250 s-1 By comparing the experimental results, both the yield strength ...

Optimal control of multiphase steel production
Journal of Mathematics in Industry, 2019 An optimal control problem for the production of multiphase steel is investigated that takes into account phase transformations in the steel slab. The state equations are a semilinear heat equation coupled with an ordinary differential equation, that ...

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Productivity and transition in Swedish iron and steel, 1870-1940 [PDF]
, 2007 This paper would like to analyse how Swedish iron and steel entrepreneurs reacted to the strains of increasing competition on world markets which affected the industry between 1870 and 1940. It implicitly searches for readjustments taken by the sector

First test of a high voltage feedthrough for liquid Argon TPCs connected to a 300 kV power supply
, 2016 Voltages above a hundred kilo-volt will be required to generate the drift field of future very large liquid Argon Time Projection Chambers. The most delicate component is the feedthrough whose role is to safely deliver the very high voltage to the ...
