Patent granted for a sheet or strip of ferrous alloy
A recently granted patent (Publication Number: US11767583B2) describes a sheet or strip of cold rolled and annealed ferrous alloy with specific composition and properties. The composition of the material consists of various weight percentages of different elements. The patent claims that the material should have a specific texture component, defined by the crystallographic orientation of the grains. This texture component should have an angular disorientation of less than 15° from a specific orientation.
Additionally, the patent specifies certain ranges for the element cobalt (Co) in the material. The cobalt content should be between 10% and 35% in the sheet or strip.
The patent also mentions that the material should have a specific volume fraction of grains. The volumetric fraction of the grains should not exceed 30% of the material.
Furthermore, the patent includes several additional claims related to the composition and properties of the sheet or strip. These claims involve specific weight percentages of other elements, such as nickel (Ni), chromium (Cr), and aluminum (Al), as well as specific ranges for the grain size and the presence of certain phases.
Finally, the patent describes the use of the sheet or strip in a transformer magnetic core. The core is made up of stacked or rolled-up sheets, and at least some of these sheets should be made of the aforementioned material.
In summary, the granted patent describes a specific composition and properties for a sheet or strip of cold rolled and annealed ferrous alloy. The material should have a particular texture component, specific ranges for cobalt content, and limitations on the volume fraction of grains. The patent also includes additional claims related to the composition and properties of the material, as well as its use in a transformer magnetic core.
