The present disclosure relates to extrusion coating systems, extrusion coated substrates, and processes for making the same. In some aspects, extrusion coating systems as described herein may include an at least partially insulated outlet wall, which may facilitate production of coated substrates exhibiting a very desirable surface texture and appearance. Coated substrates of the present invention may be utilized in a variety of end applications, including, but not limited to, interior and exterior construction materials for homes, buildings, and furniture.

Laminate BMG-fiber feedstock and parts made from one or more fiber layers and two or more bulk metallic glass (BMG) layers are described herein. The hot formed BMG-fiber laminates have vastly superior strength, ductility and use parameters as compared to the fiber or BMG alone as well as to conventional metal-fiber weaves. Methods of formation for both the BMG-fiber laminate and for near-to-net parts made therefrom are also provided.

A high performance laminated aluminum alloy manufacturing method includes: combining and fixing a front plate, a middle plate, and a rear plate, performing hot roll-bonding to obtain a laminated aluminum alloy; conducting solid solution and quenching treatment on the laminated aluminum alloy; carrying out underwater stirring friction treatment on the quenched laminated aluminum alloy; after aging heat treatment, the laminated aluminum alloy with high ballistic resistance and high interfacial bonding strength is obtained. The method uses underwater stirring friction treatment on quenched laminated aluminum alloy to break the original interlayer structure, forming a three-dimensional spatial structure composed of a stirring zone and a structural interlocked zone, and the interlayer bonding strength of the laminated aluminum alloy is greatly improved. The underwater stirring friction processing treatment of quenched aging strengthened aluminum alloy is beneficial for refining grain size, and promoting aging precipitation, which improves the ballistic resistance of laminated aluminum alloy.
