摘要： This invention is related to retention of mechanical properties in high strength steel at reduced thicknesses and which mechanical property performance is also retained at relatively high strain rates. These new steels can offer advantages for a myriad of applications where reduced sheet thickness is desirable. In addition, the alloys herein are those that retain useful mechanical properties after introduction of a geometric discontinuity and an accompanying stress concentration.

摘要： This disclosure is directed at methods for mechanical property improvement in a metallic alloy that has undergone one or more mechanical property losses as a consequence of shearing, such as in the formation of a sheared edge portion or a punched hole. Methods are disclosed that provide the ability to improve mechanical properties of metallic alloys that have been formed with one or more sheared edges which may otherwise serve as a limiting factor for industrial applications.

摘要： This disclosure deals with a class of metal alloys with advanced property combinations applicable to metallic sheet production. More specifically, the present application identifies the formation of metal alloys of relatively high strength and ductility and the use of one or more cycles of elevated temperature treatment and cold deformation to produce metallic sheet at reduced thickness with relatively high strength and ductility.

摘要： The present disclosure is directed and formulations and methods to provide non-stainless steel alloys having relative high strength and ductility. The alloys may be provided in sheet or pressed form and characterized by their particular alloy chemistries and identifiable crystalline grain size morphology. The alloys are such that they include boride pinning phases. In what is termed a Class 1 Steel the alloys indicate tensile strengths of 630 MPa to 1100 MPa and elongations of 10-40%. Class 2 Steel indicates tensile strengths of 875 MPa to 1590 MPa and elongations of 5-30%. Class 3 Steel indicates tensile strengths of 1000 MPa to 1750 MPa and elongations of 0.5-15%.

The glass forming alloy may include 43.0 atomic percent to 68.0 atomic percent iron, 10.0 atomic percent to 19.0 atomic percent boron, 13.0 atomic percent to 17.0 atomic percent nickel, 2.5 atomic percent to 21.0 atomic percent cobalt, optionally 0.1 atomic percent to 6.0 atomic percent carbon, and optionally 0.3 atomic percent to 3.5 atomic percent silicon. Furthermore, the glass forming alloy includes between 5 % to 95 % by volume one or more spinodal glass matrix microconstituents which include one or more semi-crystalline or crystalline phases at a length scale less than 50 nm in a glass matrix.
