Abstract
Described herein are methods of forming a neutron shielding material. Such material may comprise a powder blend comprising a first component comprising a blend of a first metal particle and a first ceramic particle; and a second component comprising a reinforcing chip, the reinforcing chip comprising a second ceramic particle dispersed within a chip metal matrix.
Claims20
A method of forming a neutron shielding material comprising:
- a) mixing together a first metal particle having a first grain growth temperature;
- a first ceramic particle;
- and a reinforcing chip to form a powder blend;
- and
- b) sintering the powder blend into a billet and extruding the billet at a hot-work temperature;
- wherein the reinforcing chip comprises a second ceramic particle homogeneously dispersed within a chip metal matrix having a second grain growth temperature;
- wherein the first metal particle is virgin aluminum powder;
- and
- wherein the hot-work temperature is lower than both of the first and second grain growth temperatures.
