Abstract: A method for determining one or more material conditions of a hysteretic ferromagnetic material and/or a nonhysteretic material can include interrogating the hysteretic ferromagnetic material and/or the nonhysteretic material with an input time varying magnetic field and detecting a magnetic response and/or acoustic response over time from the hysteretic ferromagnetic material and/or the nonhysteretic material. The method can also include determining a time dependent nonlinear characteristic of the received magnetic response and/or acoustic response and correlating the time dependent nonlinear characteristic of the received magnetic response or acoustic response to one or more material conditions of the material.

Abstract: Provided is a method of utilizing a nondestructive evaluation method to inspect/screen steel components (like plates), steel metal pipes, and seam welds and girth welds of the pipes to identify material phases and assess material qualities. The method includes: providing a DC magnetic field from a magnet to a steel plate, pipe, or weld composed of at least one hysteretic ferromagnetic material followed by scanning the plate, pipe, or weld and recording magnetic responses from two or more suitable sensors disposed at locations with different magnetic field strengths in the regions of interest configured to receive magnetic responses; and correlating all the said received magnetic responses to one or more material qualities and/or material phases of the plate, pipe, or weld. The one or more material qualities includes regions of higher hardness, regions of metal loss, regions of surface cracks, amount of undesirable phases, and combinations thereof.

Abstract: Methods disclosed herein include using additive manufacturing to create a joint between a first metallic material and a second metallic material that is different from the first metallic material, wherein the porosity of the joint is less than about 0.1 percent by volume measured according to ASTM B-962. The additive manufacturing can be performed such that no intermetallic brittle phase forms between the first metallic material and the second metallic material.
