Book Description
Crystallographic changes in several irradiated metal boride systems were studied by x-ray diffraction techniques. Three structures were investigated quite extensively and a fourth examined in a cursory manner. Irradiation damage can be related to structure. The relationship does not depend primarily upon the crystal system, but rather upon the strength of the structure bonds. The metal diborides with their tightly bonded hexagonal structures are most resistant to radiation damage. The hexaborides on the other hand, have a loosely bonded cubic structure and arc extensively damaged by radiation. The tetraborides are intermediate in bond lengths and also are intermediate in structure damage. A very limited study was made of irradiated dodecaborides. This face-centered cubic structure has an intermediate bond length between metal and boron atoms but a long bond length between metal atoms. The damage to this structure was apparently quite extensive as determined from the limited data available. (auth).

Radiation Effects in Borides, Part I - Helium Release and Swelling in Irradiated Borides

Book Description
The principal objective of the work being reported was to irradiate a variety of borides in order to assess the relationship of crystal structure to helium retention and structural changes. A secondary objective was to compare the irradiation behavior of powders and dense solids. Another objective was to compare the behavior of borides with similar crystal structures but having metal atoms with vastly different absorption cross-sections, for example, zirconium and hafnium diborides.

Book Description
During the post-irradiation examination of borides it was discovered that the samples which had been irradiated as powders had sintered into firmly bonded bodies. This radiation sintering occurred at temperatures hundreds of degrees below that required to produce similar interparticle bonding by the application of heat alone., This report discusses the results of the postirradiation examination of some of these borides which were irradiated as powders and compares the results of our observations with the reports of simiiar radiation sintering occurring in other materials.
