Abstract
The invention provides a component or composite part, such as a divertor plate for the “first wall” of a fusion reactor, adapted to endure a high thermal load, which is made, at least in some sections, of tungsten or a tungsten alloy. In accordance with the invention, the sections are not constructed massively from tungsten or a tungsten alloy, but rather are made as a laminated packet, in order to improve the susceptibility to fissures.
Claims7
A composite product for enduring high thermal stress comprised of at least two sections of a particle-reinforced alloy comprised of 0.3-5 volume % lanthanum oxide and the remainder tungsten, wherein the sections are formed together as a laminated packet in abutting relation in a mechanically and thermally stable manner.
A composite product for enduring high thermal stress comprised of at least two sections of a tungsten alloy,
- wherein the sections are formed together as a laminated packet, and
- wherein the product is actively cooled with a cooling agent conducting tube comprised of copper or a copper alloy, which conducting tube is surrounded on all sides by said laminated packet.
A composite product for enduring high thermal stress comprised of at least two sections of a tungsten alloy,
- wherein the sections are formed together as a laminated packet, and
- wherein the product is a divertor plate for use as a first wall in a fusion reactor.
A composite product for enduring high thermal stress comprised of at least two sections of tungsten, wherein the sections are formed together as a laminated packet in abutting relation in a mechanically and thermally stable manner, and wherein the product is actively cooled with a cooling agent conducting tube comprised of copper or a copper alloy, which conducting tube is surrounded on all sides by said laminated packet.
