WINDOW FOILS FOR ELECTRON BEAM PROCESSORS

摘要

A window foil for use in an electron beam processor comprising a heat-treatable titanium alloy that provides excellent cold formability and incrased yield strength as well as high creep resistance at elevated temperatures. The improved creep resistance at high temperatures assures prolonged window foil service. In particular, alpha-beta titaniums and beta titaniums (alloys) that are heat-treatable are of interest to this invention.
