<p>A method of manufacturing a metal component from metal powder comprises preparing (12) a metal powder, providing (14) gallium on at least part of the surface of at least some of the metal powder particles, encapsulating (16) the metal powder in a container, evacuating (18) the container to remove air and/or gas from the container, sealing (20) the container, hot isostatically pressing (22) the container to consolidate the metal powder particles to produce the metal component and removing (24) the container from the metal component. The process is used to produce gas turbine engine metal components, for example turbine discs with improved fatigue properties.</p> |
