摘要： A controlled thermal coefficient product manufacturing system and method is disclosed. The disclosed product relates to the manufacture of metallic material product (MMP) having a thermal expansion coefficient (TEC) in a predetermined range. The disclosed system and method provides for a first material deformation (FMD) of the MMP that comprises at least some of a first material phase (FMP) wherein the FMP comprises martensite randomly oriented and a first thermal expansion coefficient (FTC). In response to the FMD at least some of the FMP is oriented in at least one predetermined orientation. Subsequent to deformation, the MMP comprises a second thermal expansion coefficient (STC) that is within a predetermined range and wherein the thermal expansion of the MMP is in at least one predetermined direction. The MMP may be comprised of a second material phase (SMP) that may or may not transform to the FMP in response to the FMD.

摘要： A production method for a steel component includes preparing a patchwork material including steel sheets that are laid one on another, at least one of overlap surfaces of the steel sheets including a zinc-based plating layer, heating the patchwork material, and performing hot stamping on the patchwork material heated to form the steel component in which a joint part between the steel sheets is disposed in a bent area. When tout denotes a sheet thickness of a steel sheet located on an outer side in the bent area, and tin denotes a sheet thickness of a steel sheet located on an inner side, tout/tin≥1.1 is satisfied. The joint part is disposed in a ridge portion or at a position in a vicinity of the ridge portion, and the position satisfies d/tin

摘要： A Z-shaped attachment element for use in building construction is disclosed. The Z-shaped attachment element is made from a single piece of sheet metal that is first cut and then bent to form the Z-shaped cross-sectional profile. The Z-shaped attachment element comprises: an elongated upper flange; an elongated lower flange, wherein the upper and lower flanges are spaced apart and substantially parallel to each other; an elongated middle web section between, and connected to, the upper and lower flanges along respective upper and lower lengthwise bends (wherein the middle web section is diagonal in relation to the position of the upper and lower flanges, thereby defining a generally Z-shaped cross-sectional profile); and a plurality of notches formed along the lower lengthwise bend and into the lower flange and the adjoining middle web section, but not into the upper bend or the upper flange, of the Z-shaped sheet metal attachment element.
