Abstract: This invention provides methods of treatment for welded products by pulse impact energy, preferably ultrasonic, at original production, during the active life period for maintenance and after failure in a repair stage to improve the strength at the weld sites and to fashion stress patterns that reduce stress centers and micro-stress defects. The basic method steps are nondestructive in nature, inducing interior pulse compression waves that temporarily plasticize the metal to relax stresses and redistribute stress patterns in a gradient of metallic grain structure between a higher strength substantially grainless white layer at the weld seam to an internal base metal region in the welded body. Thus, a renewed longer life span and higher strength weld joint regions are generated in welded products.

Abstract: The present invention pertains to a method for modifying the structure of near-surface thin material layers in solids, to be applied inter alia for crystallizing amorphous materials and modifying the crystal structure of semiconductors, high temperature supraconductors and non conductors. The inventive method consists in exposing the solid material to short and powerful steep-sloped laser impulses, thereby generating on the exposed surface a plasma which triggers a pressure wave or a chock wave penetrating the material to be modified. The energy density of the laser impulses must be high enough to generate the plasma, but not so high as to cause an ablation of the exposed material layer. The effect obtained using said method is particularly useful when the generated plasma is to be inertially confined by covering the surface to be exposed with a material which lets the laser rays through.

Abstract: An Al—Si coated press hardening component, wherein the Al—Si coating comprises a low-Al content ferrite layer with an Al content of less than 5 wt % and a thickness of greater than 5 μm, and having a maximum bending angle of the Al—Si coated press hardening component is greater than 65°.

At the same time, the hot stamping process of the present invention can take into account or optimize the microstructure of the steel substrate to further improve the bendability and tensile property of the whole material.

Abstract: A method of generating twin lamellas in a metal body includes the steps of introducing the metal body into a chamber, filling the chamber with a cooling medium having a temperature that will enable generation of twin lamellas in the metal body upon deformation thereof, and deforming the metal body while the latter is surrounded by the cooling medium. The cooling medium surrounds the metal body upon deformation of the latter is in a gaseous state. The present disclosure also relates to a device for generating twin lamellas in the metal body, the device including a chamber, a chamber inlet connected to a cooling medium source, and a deformation device arranged to deform the metal body. The deformation device is positioned inside the chamber so that the metal body will be surrounded by the cooling medium in a gaseous state while being deformed by the deformation device.
