Ceramic matrix composite components and methods for fabricating ceramic matrix composite components are provided. In one example, a ceramic matrix composite component includes a ceramic matrix composite body. The ceramic matrix composite body includes a layer-to-layer weave of ceramic fibers and a layer of 1-directional and/or 2-directional (1D/2D) fabric of ceramic fibers disposed adjacent to the layer-to-layer weave. When stressed, the ceramic matrix composite body forms a relatively high through-thickness stress region and a relatively high in-plane bending stress region. The layer-to-layer weave is disposed through the relatively high through-thickness stress region and the layer of 1D/2D fabric is disposed through the relatively high in-plane bending stress region.

A method for forming a connection such as an electrical connection, to a fiber material electrode element comprises moving a length of the fiber material relative to a pressure injection stage and pressure impregnating by a series of pressure injection pulses a lug material into a lug zone part of the fiber material to surround and/or penetrate fibers of the fiber material and form a lug strip in the lug zone. The fiber material may be a carbon fiber material and the lug material a metal such as Pb or a Pb alloy. Apparatus for forming an electrical connection to a fiber material electrode element is also disclosed.

A die cast component includes an insert element with a plurality of form-fitting elements which are designed for the form-fitting connection of the insert element with a casting material. A ratio of a component wall thickness to a wall thickness of the insert element is a maximum of 4.

A method for increasing the fatigue strength of a tubular semifinished product for a medical implant, such as a stent or a cardiac valve, which includes providing a tubular semifinished product formed from a bioresorbable magnesium alloy, iron, or an iron-based alloy; and applying pressure at a temperature equal to, or less than, 420 C., internally against an inner surface of the tubular semifinished product such that the outer circumference of the tubular semifinished product is subject to plastic deformation by at least 0.2%.

Provided is a titanium cast product made of commercially pure titanium, the titanium cast product being produced by electron-beam remelting or plasma arc melting, comprising: a melted and resolidified layer in a range of 1 mm or more in depth at a surface serving as a surface to be rolled, the melted and resolidified layer being obtained by adding one or more kinds of stabilizer elements to the surface and melting and resolidifying the surface. An average value of stabilizer element(s) concentration in a range of within 1 mm in depth is higher than stabilizer element(s) concentration in a base material by, in mass %, equal to or more than 0.08 mass % and equal to or less than 1.50 mass %. As the material containing the stabilizer element, powder, a chip, wire, or foil is used. As means for melting a surface layer, electron-beam heating and plasma arc heating are used.
