摘要： The present invention in one or more embodiments provides a vehicle roof structure which includes a cast node including a pillar portion for receiving a pillar and a roof-rail portion for receiving a roof rail, the roof-rail portion having first and second ends, which may have a closed first cross-section and a closed second cross-section, respectively. The closed first cross-section may be different from the closed second cross-section such that the first and second ends are to receive two individual roof rails of different dimensions. The closed first cross-section may be larger in opening dimension than the closed second cross-section, when the first end is positioned closer to a front of the vehicle than the second end.

摘要： A high fatigue strength aluminum alloy comprises in weight percent copper 3.0-3.5%, iron 0-1.3%, magnesium 0.24-0.35%, manganese 0-0.8%, silicon 6.5-12.0%, strontium 0-0.025%, titanium 0.05-0.2%, vanadium 0.20-0.35%, zinc 0-3.0%, zirconium 0.2-0.4%, a maximum of 0.5% other elements and balance aluminum plus impurities. The alloy defines a microstructure having an aluminum matrix with the Zr and the V in solid solution after solidification. The matrix has solid solution Zr of at least 0.16% after heat treatment and solid solution V of at least 0.20% after heat treatment, and both Cu and Mg are dissolved into the aluminum matrix during the heat treatment and subsequently precipitated during the heat treatment. A process for heat treating an Al—Si—Cu—Mg—Fe—Zn—Mn—Sr-TMs alloy comprises heat treating the alloy to produce a microstructure having a matrix with Zr and V in solid solution after solidification.

摘要： A process of heat treating an Al—Si—Cu—Mg—Fe—Zn—Mn—Sr-TMs alloy, where the TMs include Zr and V, includes heat treating the alloy to produce a microstructure having a matrix with Zr and V in solid solution after solidification. The solid solution Zr, in wt. %, is at least 0.16%, the solid solution V, in wt. %, is at least 0.20% after heat treatment, and Cu and Mg are dissolved into the matrix during the heat treatment and subsequently precipitated during the heat treatment. The composition of the alloy, in wt. %, includes Cu between 3.0-3.5%, Fe between 0-0.2%, Mg between 0.24-0.35%, Mn between 0-0.40%, Si between 6.5-8.0%, Sr between 0-0.025%, Ti between 0.05-0.2%, V between 0.20-0.35%, Zr between 0.2-0.4%, maximum 0.5% total of other alloying elements, and balance Al.

摘要： A method of manufacturing a part includes melting, rapidly solidifying and consolidating pre-alloyed powders using an additive manufacturing process. The method provides a finished part with a microstructure with at least one non-equilibrium phase. The pre-alloyed powders can be powders of aluminum alloyed with iron and molybdenum, and the additive manufacturing process forms a near-net shaped part that can be finished with techniques such as machining, polishing and drilling, among others. The additive manufacturing process can be a laser melting technique such as selective laser melting or laser metal deposition and an average dendrite arm spacing of the rapidly solidified and consolidate pre-alloyed powders is less than 1.0 μm. Finished parts formed from the aluminum alloy powders alloyed with iron and molybdenum exhibit enhanced strength at elevated temperatures such as an ultimate tensile strength greater than 400 MPa at 300° C. and greater than 350 MPa at 350° C.
