Abstract

Metals such as titanium alloy blanks which are subject to contamination by air at elevated temperatures are precision formed into desired shapes in a controlled environment. The metal worksheet and a shaping member are located within an enclosure. An inert gas environment is provided in the enclosed area. The metal worksheet is heated to a suitable forming temperature and stretched substantially in excess of its original surface area under tensile stress from a fluid pressure loading and formed into the desired shape by interaction with the shaping member. Novel sealing arrangements for the enclosed area of the forming apparatus are provided.
