Abstract
A method of forming or treating an article or preform (10) and an article or preform made according to the method are provided. The method includes the step of providing around at least part of the article or preform (10) a generally tubular element (14) whose effective cross-section tends to reduce on extension, and applying an extension load to the tubular element (14) thereby to apply a compression load to the exterior of the article or preform to aid consolidation thereof.
