摘要： Method for joining of at least two unweldable materials, non-weldable directly to each other with thermal joining processes in a lap joint configuration, where a two step sequence is used consisting of a first step to apply a thermomechanical or mechanical surface protection layer on the surface of an unweldable material and a second step, where a thermal joining process is used to joint the sprayed layer with an applied layer sheet.

摘要： The invention relates to a method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned between at least two metallic layers. At least one of the metal layers is shaped into a three dimensional layer, and the metal layers are in direct mechanical contact to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions in a subsequent manufacturing process.

摘要： A method for partial hardening of an austenitic steel by utilizing during cold deformation the TWIP (Twinning Induced Plasticity), TWIP/TRIP or TRIP (Transformation Induced Plasticity) hardening effect. Cold deformation is carried out by cold rolling at least one surface of the steel with forming degree (Φ) of 5≤Φ≤60% in order to achieve in the steel at least two consecutive areas with different mechanical values in thickness, yield strength (Rp0.2), tensile strength (Rm) and elongation, having a ratio (r) between the ultimate load ratio (ΔF) and the thickness ratio (Δt) of 1.0>r>2.0, and in which the areas are mechanically connected to each other by a transition area having a thickness that is variable from the thickness of the first area in the deformation direction to the thickness of the second area in the deformation direction.

摘要： The present invention relates to a method for manufacturing a complex-formed component by using austenitic steels in a multi-stage process where cold forming and heating are alternated for at least two multi-stage process steps. The material during every process step and a component produced has an austenitic microstructure with non-magnetic reversible properties.

摘要： A method for manufacturing a component with high work hardening rate made of a material having an austenitic microstructure. A cold work hardened material for a component is heat treated to create at least one softened area with high ductility and lower strength than the initial high strength material by heat treating a part of the component material required for the softened area. Also, a use of the component.

摘要： A method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned between at least two metallic layers. At least one of the metal layers is shaped into a three dimensional layer and the metal layers are material closured to each other by a tack weld on the metallic contacts between the metallic layers to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions.
