Interface Separation-Lubrication Substances for Isothermal Forging at 1300F to 1500F.
Abstract
A program to develop and formulate separation-lubrication compositions for isothermal forging of beta titanium alloys in the temperature range from 1300F to 1500F was successfully completed. Several hundred compositions were chosen at the start of the program, mostly of the vitreous-phase-particulate type, containing boundary film additives or stable semi-abrasives. The field was narrowed to 28 low friction (LFC) types, 12 controlled friction (CFC) types and 8 molten salt (MSC) types. These were further evaluated through quantitative measurement of their application, fusion, stability, densification, accumulation and adhesion characteristics. Optimum combinations of these factors were selected through a simplified multifactor desirability analysis and eight final compositions were selected for further evaluation of their friction reducing properties through ring compression forging at the Westinghouse hot die isothermal forging facility at Wright-Patterson Air Force Base. These compositions included three of the LFC type, one CFC type and one molten salt type for service at the low end of the temperature range (near 1350F) on ferrous alloy dies, and three LFC type for service on nickel alloy dies at the high end of the thermal range (near 1500F).
