摘要： A method of applying a metallic alloy overlay including providing an iron based feedstock powder including 10 to 75 weight percent iron and manganese, 10 to 60 weight percent of chromium, 1 to 30 weight percent of an interstitial element selected from boron, carbon, silicon or combinations thereof, 0 to 40 weight percent of a transition metal selected from molybdenum, tungsten or combinations thereof and 1 to 25 weight percent niobium. The method also includes providing an electrode including at least 50 weight percent iron and depositing a weld overlay with the feedstock powder and the electrode to create a metallic alloy exhibiting a grain size in the range of 1,000 mum or less.

摘要： The present disclosure is directed and formulations and methods to provide alloys having relative high strength and ductility. The alloys may be provided in seamless tubular 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 700 MPa to 1400 MPa and elongations of 10-70%. Class 2 Steel indicates tensile strengths of 800 MPa to 1800 MPa and elongations of 5-65%. Class 3 Steel indicates tensile strengths of 1000 MPa to 2000 MPa and elongations of 0.5-15%.
