<p>A method of forming internal high temperature barriers in structural metals is provided. The barriers prevent movement of boundaries and dislocations inside the structural metal, and make structural metals creep-resistant at high homologous temperatures. The method comprises providing a first layer of structural metal, such as tungsten, molybdimum or rhenium, implanting ions, such as potassium, into this layer, and layering a second layer of structural metal on the ion-implanted first layer to form a laminated product. The steps of implanting and layering can be repeated an arbitrary number of times.</p> |
