[Object] There is provided a long structural member made of metal, which has a substantially gutter-shaped cross section and is excellent in load transfer properties when an impact load is applied.

[Solution] A structural member made of metal, formed so as to extend long in a predetermined direction, and having a gutter bottom, two ridges continuing to both ends in a width direction of the gutter bottom, and two vertical walls continuing to the two ridges, includes an outward continuous flange continuously formed at least along the gutter bottom, the ridges, and the vertical walls at an end in the predetermined direction, in which a width of the gutter bottom is reduced as a distance from the end having the outward continuous flange becomes larger.

A method may be used to produce a component that includes at least two different materials. The method may involve providing a hardenable planar or preformed steel sheet or steel profile, completely or partially heating the steel sheet or steel profile to the austenitic temperature, inserting the heated steel sheet or steel profile into a first tool for hot forming and/or press hardening the steel sheet or steel profile to give a completely or partially hardened steel workpiece. In the course of the hot forming and/or press hardening at least one jog is made in the steel sheet or the steel profile. The jog may serve for fastening at least one second material thereto.”

Method of manufacturing a metal structural component (E) for a vehicle, comprising the steps of a) providing a planar blank (B); b) cutting out the blank (B) to create an opening (A) having a first portion (Q) and wherein the first portion (Q) of the opening A) has a second length (lt) in a first transverse direction (T); c) welding a patch (P) to the blank (B) so as to cover the opening (A), the patch (P) being made of the metal having greater ductility than the material of the blank (B); d) stamping the assembly formed by the blank (B) and the patch (P) to obtain the component (E).

A vehicle body includes a roof rail elongated along a longitudinal axis, and first and second bows each connected to the roof rail. A brace includes a base, a first arm and a second arm. The base is elongated along the longitudinal axis, with the first arm extending from the base along the first bow and fixed to the first bow, and the second arm spaced from the first arm and extending from the base along the second bow and fixed to the second bow.

A hybrid structural assembly for a motor vehicle includes a casting and a structural inlay. The casting includes a plurality of structural components joined together in a casting process to form structural load paths and extending in a plurality of directions in a 3D space. The casting includes a cast-allowable alloy material. The structural inlay is secured to at least one of the structural components. The structural inlay includes a material having at least one of a higher ductility and a higher toughness than the cast-allowable alloy material.

An Al-plated steel sheet includes: a steel sheet; an Al plating layer which is formed on one surface or both surfaces of the steel sheet and contains at least 85% or more of Al by mass %; and a surface coating layer which is laminated on the surface of the Al plating layer and contains ZnO and one or more lubricity improving compounds.

A vehicle body front reinforcement assembly includes: a front side beam connected to a front of a dash panel; a side sill connected to a side end portion of a floor panel; and a torque box extending from the dash panel to the side end portion of the floor panel and connecting a rear end of the front side beam to a front end of the side sill, wherein the side sill includes: a side sill coupler coupled to a rear end of the torque box; and a side sill extension connected to a rear end of the side sill coupler and extending towards the rear of a vehicle, and wherein the side sill coupler is made of a material having a lower tensile to strength than the material of the side sill extension.

The present invention provides a pillar member of a vehicle, which is characterized by comprising: a pillar main body portion; and a connecting and joining portion provided on both ends of the pillar main body portion and coupled to a vehicle body. The pillar main body portion and the connecting and joining portion are consecutively formed. The connecting and joining portion includes: a first connecting and joining portion provided on one side of the pillar main body portion; and a second connecting and joining portion provided on the other side of the pillar main body portion so as to face the first connecting and joining portion. The pillar main body portion is consecutively formed through a roll forming technique in a region between the first connecting and joining portion and the second connecting and joining portion, and has an odd number of closed cross section portions formed therein.

A cast-in insertion member out of which a core inserted during casting of cast portion can easily be pulled, and production method thereof are provided. Inside covering portion is formed to cover the interior of one end of pipe. During the casting, inside covering portion is interposed between the inner surface of the one end of pipe and the outer surface of the tip of the core put into pipe, so that a bite between pipe and the core by contraction of pipe due to molding shrinkage of cast portion can be prevented. Inside covering portion includes tapered surface on the side of recess, which gradually widens from the one end to the other end of pipe. After molding of cast portion, tapered surface making contact with the outer surface of the tip of the core gradually widens in the direction opposite to that of putting the core into pipe.

The vehicle underbody structure (20) includes a floor panel (24) and an underbody reinforcement element (26), the underbody reinforcement element (26) including at least a front transversal beam (112a, 112b) and a rear transversal beam (114), the transversal beams (112a, 112b, 114) extending parallel to each other and being attached to the floor panel (24). The front transversal beam (112a, 112b) and the rear transversal beam (114) are made of a press hardening steel having a tensile strength higher than or equal to 1300 MPa.
