Disclosed is an alloy which comprises, as alloy elements, at least the following (in % by weight): manganese, in particular from 10%-16%, very particularly preferably from 12% to 15%, chromium, in particular from 3% to 10%, very particularly preferably from 5% to 8%, aluminum, in particular from 1% to 6%, very particularly preferably from 2% to 4%, titanium, in particular from 1% to 6%, very particularly preferably from 2% to 4%, nickel, in particular nickel as balance, very particularly preferably nickel-based.

Described is a magnetocaloric regenerator comprising one or more materials containing cobalt, manganese and boron and optionally carbon.

A sample composed of a nickel-based metal is immersed in a corrosive solution (aqueous solution containing an acid and sodium chloride). The sample that has been immersed in the corrosive solution is exposed to a flame of engine oil, and further heated. By immersing the sample in the particular corrosive solution, a Ni-enriched phase which is deficient in additional elements and in which the Ni concentration increases is formed in a surface layer region of the sample. By exposing the sample having the Ni-enriched phase to the flame of the engine oil, components in the engine oil are activated and brought into contact with the sample to form a low-melting point phase in the surface layer region of the sample. By heating the sample having the low-melting point phase to melt the low-melting point phase and resolidifying the low-melting point phase, particles and the like can be formed depending on the type of material of the sample. The ease of the generation of particles can be evaluated by using simple equipment instead of an engine for testing.

A turbine component having a face-centered cubic ferromagnetic damping coating with high damping loss attributes applied in a non-molten solid state.

For a steel sheet for hot pressing having a coating layer to prevent scale formation, adhesion of metals to heating equipment is reduced, liquid metal embrittlement cracking during hot press forming is prevented, and excellent post-painting corrosion resistance is achieved. A coated steel sheet for hot pressing includes: a base steel sheet; and a coating layer of 7 m to 20 m in thickness provided on both sides of the base steel sheet, wherein the coating layer is made of Ni or a Ni-based alloy, and a Zn content in the coating layer is 0 mass % to 10 mass %.

A method for manufacturing a strip having a variable thickness along its length, comprising the steps: an initial strip of constant thickness is provided; homogeneous cold rolling of the initial strip along its length in order to obtain an intermediate strip of constant thickness along the rolling direction; flexible cold rolling of the intermediate strip along its length in order to obtain a variable thickness strip, having, along its length, first areas with a first thickness (e+s) and second areas with a second thickness (e), less than the first thickness (e+s), continuous annealing of the strip.

The plastic deformation ratio generated, after an optional intermediate recrystallization annealing, by the homogeneous cold rolling and the flexible cold rolling steps in the first areas is greater than or equal to 30%.

Provided is a steel sheet for hot pressing that has excellent suitability for high-speed heating, resists liquid metal embrittlement cracking, and has excellent paint adhesion after hot pressing. A steel sheet for hot pressing comprises: a base steel sheet; and a coating layer of 0.5 m to 6.0 m in thickness provided on both sides of the base steel sheet, wherein the coating layer is made of Ni or a Ni-based alloy, and a Zn content in the coating layer is 0 mass % to 30 mass %.
