    摘要： A syntactic metal foam composite that is substantially fully dense except for syntactic porosity is formed from a mixture of ceramic microballoons and matrix forming metal. The ceramic microballoons have a uniaxial crush strength and a much higher omniaxial crush strength. The mixture is continuously constrained while it is consolidated. The constraining force is less than the omniaxial crush strength. The substantially fully dense syntactic metal foam composite is then constrained and deformation worked at a substantially constant volume. This deformation causes at least work hardening and grain refinement in the matrix metal. The resulting deformed syntactic metal foam composite has an energy absorption capacity that is at least 1.5 to 2 or 3 times or more the energy absorption capacity of the precursor substantially fully dense syntactic metal foam composite.

    摘要： The invention is directed to a method for caulking a caulking member such as a caulking nut or a caulking bolt to a metal plate. The metal plate is arranged on a die having a caulking protrusion formed on an end surface thereof, the caulking member is arranged on the metal plate while a position of a caulking recess portion of the caulking member is aligned with the caulking protrusion, and a punch is brought closer to the die so that the caulking member is pressed against the metal plate. While an upper surface of the metal plate in a position opposite to the caulking recess portion is restricted by a downward protruding portion of the punch or by the caulking member, the metal plate is plastically fluidized into the caulking recess portion, so that the caulking member is caulked without boring a hole in the metal plate.

    摘要： The manufacturing method comprises the steps of: carrying out one or more forming operations so as to give the desired geometry to the part; and subjecting the part thus formed to a single heat treatment having only a stress relieving treatment, which is preferably carried out at a temperature in the range from 530° C. to 580° C. for a time in the interval from 45 to 60 minutes and is followed by cooling of the part in air. By virtue of the formed part being subjected to a stress relieving heat treatment, the residual stress state due to the initial forming process and to the bead welding, if any, is eliminated or at least significantly reduced.

    摘要： A method of forming a shaped product from an initial blank comprises subjecting the initial blank to a hot forming and press hardening operation to form the shaped product with substantially a uniform first tensile strength. Subsequently, the shaped product is at least partially immersed into a fluidized bed that is maintained within a known range of operating temperatures. While the shaped product is immersed into the fluidized bed, a first region of the shaped product is heated selectively to above a known temperature. The first region is then cooled, such that the first region attains a second tensile strength that is substantially less than the first tensile strength.
