摘要： A metal can include a metallic substrate and an alloy coating. The alloy coating may have a higher entropy than the entropy of the metallic substrate. The alloy coating may coat an external surface of the metallic substrate. The metal coated by the higher entropy alloy on an external surface of the metallic substrate may serve to increase resistance of the metal to hydrogen-induced cracking in a downhole environment.

摘要： A composite material has a plate shape and has a first surface and a second surface. The second surface is opposite to the first surface. The composite material includes a plurality of first layers and at least one second layer. The first layers and the second layer are alternately layered along a thickness direction of the composite material such that the first layers are located at the first surface and the second surface. Each of the first layers is a layer including copper. The second layer is a layer of a molybdenum powder compact impregnated with copper. A compressive residual stress of 50 MPa or less acts on each of the first layer located at the first surface and the first layer located at the second surface.

摘要： The present invention relates to the technical field of material processing and provides a method for making a metal material composite, including: contacting a first surface of a first plate with a second surface of a second plate; placing the first plate and the second plate in a recess in a circumferential direction of a first roller such that a third surface of the second plate contacts a bottom wall of the recess in a circumferential, the third surface being opposite the second surface, the first plate having a greater hardness than the second plate; and controlling a first roller and a second roller to rotate, thereby rolling to combine the first plate and the second plate into a composite plate, where a fourth surface of the first plate contacts a surface of the second roller and the fourth surface is opposite the first surface during the rolling. According to the method for making a metal material composite in the present invention, flashings and burr on the side edges of a composite plate are avoided by placing the first plate and the second plate in a recess for machining.

摘要： A method produces a steel sheet having a microstructure including, in area fraction, 20% to 50% intercritical ferrite, 10% to 20% retained austenite, 25% to 45% tempered martensite, 10% to 20% fresh martensite, and bainite. The sum of tempered martensite and bainite is between 30% and 60%. A cold-rolled steel sheet provided includes 0.18% ≤C≤0.25%, 0.9% ≤Si≤1.8%, 0.02% ≤Al≤1.0%, with 1.00% ≤Si+Al≤2.35%, 1.5% ≤Mn≤2.5%, 0.010% ≤Nb ≤0.035%, 0.10% ≤Cr≤0.40%. The steel sheet is annealed to obtain 50% to 80% austenite and 20% to 50% of ferrite, quenched at a cooling rate between 20° C/s and 50° C/s to between Ms-50° C. and Ms-5° C., heated to a partitioning temperature between 375° C. and 450° C. and maintained at the partitioning temperature for at least 50s, then immediately cooled to room temperature.

摘要： It is an object to provide a substrate for epitaxial growth having a metal base material laminated with a copper layer. On a surface of the copper layer, an area occupied by crystal grains having crystal orientations other than a (200) plane present within 3 μm from the surface can be less than 1.5%. A surface roughness along a same direction as a rolling direction per unit length of 60 μm when measured by AFM can be Ra1
