Abstract

The present invention provides a method of diffusion bonding a first article containing a thermally activated expansion agent to a second article. The first article and the second article are placed adjacent to each other at a bonding area. The first article and the second article are constrained such that contact is maintained between the first article and the second article at the bonding area. The constrained articles are then heated at a temperature that causes the first article to expand, creating pressure between the articles at the bonding area.
