The present invention relates to a 3D-printed cobalt-based alloy product comprising carbon, tungsten and chromium with very good mechanical and thermal properties as well as a method of preparing the 3D-printed product and a powder alloy. The alloy has a high carbon content leading to high carbide content but small and evenly distributed carbides. A method facilitating 3D printing of high carbide content alloys such as the present alloy is also disclosed.

A steel sheet has a predetermined chemical composition and a metal structure represented by, in area fraction, polygonal ferrite: 40% or less, martensite: 20% or less, bainitic ferrite: 50% to 95%, and retained austenite: 5% to 50%. In area fraction, 80% or more of the bainitic ferrite is composed of bainitic ferrite grains that have an aspect ratio of 0.1 to 1.0 and have a dislocation density of 8×10.sup.2 (cm/cm.sup.3) or less in a region surrounded by a grain boundary with a misorientation angle of 15° or more. In area fraction, 80% or more of the retained austenite is composed of retained austenite grains that have an aspect ratio of 0.1 to 1.0, have a major axis length of 1.0 μm to 28.0 μm, and have a minor axis length of 0.1 μm to 2.8 μm.

A high-strength coatings and methods of fabrication to yield single-crystal-like nickel containing nanotwins and stacking faults.

A thermal insulation member is directly or indirectly sandwiched between a first object and a second object and thereby suppresses or interrupts heat transfer between the first object and the second object. The thermal insulation member comprises: a first main surface opposed to the first object; and a second main surface positioned on the opposite side from the first main surface and opposed to the second object. The thermal insulation member has a porous structure of ceramic having pores. ZrO.sub.2 particles and different type material exist on surfaces of the ZrO.sub.2 particles form a skeleton of the porous structure. The different type material includes at least one selected out of SiO.sub.2, TiO.sub.2, La.sub.2O.sub.3, and Y.sub.2O.sub.3.

There is provided a metal member capable of effectively preventing a coating layer from peeling off from a base. The metal member in an embodiment is a metal member that is used in a solid-oxide type electrochemical stack, and includes: a base formed of ferritic stainless steel; and a metal film provided on the base, in which the metal film includes a first metal layer containing Co and a second metal layer made of Mn, and is a stack in which the first metal layer and the second metal layer are sequentially stacked from the side of the base.

A steel sheet is provided with a coating having at least one layer of zinc and a top layer of paint applied by cataphoresis. The zinc layer is deposited by a jet vapor deposition process in a deposition chamber maintained at a pressure between 6.Math.10.sup.−2 mbar and 2.Math.10.sup.−1 mbar. A fabrication method and an installation are also provided.

An operable panel for an appliance includes a metallic outer wrapper having a perimetrical wrapper edge that partially defines a perimetrical breaker channel, an inner liner and a plurality of corner brackets disposed proximate the perimetrical wrapper edge. Each corner bracket cooperates with the perimetrical wrapper edge to fully define the perimetrical breaker channel. A trim breaker is adhered to the metallic outer wrapper and the corner brackets at the perimetrical breaker channel and having a liner channel that receives a portion of the inner liner. The trim breaker extends between the inner liner and the outer wrapper. An insulation material is disposed within an insulating cavity defined between the inner liner and the outer wrapper.
