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.

A cooling system including a first sheet steel item having a first surface configured to accommodate one or more objects to be cooled, and a second surface joined to a first surface of a second sheet steel item forming a shell. The items may be joined by a weld, a rivet or a plurality thereof. At least one of the second surface of the first sheet steel item and the first surface of the second sheet steel item may be formed to produce one or more conduits for forming one or more channels, whereby said joining forms said channels for coolant in a space between the second surface of the first sheet steel item and the first surface of the second sheet steel item.

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.

The invention relates to a supporting housing for a battery compartment of electric drive vehicles by using flat metallic sheets as deep-drawn shells which are fitted into each other whereby at least one double-floor is created into which a passive and partly integrated thermal management system for cooling and heating is integrated. The invention also relates to the integration of further functionality-elements like sensors for status measurement are integrated into the 'double-floor' and connected with the battery management system.

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 (&#x3a6;) of 5&#x2264;&#x3a6;&#x2264;60% in order to achieve in the steel at least two consecutive areas with different mechanical values in thickness, yield strength (R), tensile strength (Rm) and elongation, having a ratio (r) between the ultimate load ratio (&#x394;F) and the thickness ratio (&#x394;t) of 1.0&#x3e;r&#x3e;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.

The present invention relates to a method for manufacturing a component of austenitic TWIP or TRIP/TWIP steel. A flat product () is deformed by achieving at least one indentation () on at least one surface of the flat product () in order to have in the deformed product () areas of a high strength steel embedded in a matrix of a ductile material. The invention also relates to the use of the component where areas of a high strength steel embedded in a matrix of a ductile material are required in the same component.
