| Abstract: | In this paper the superplastic tensile deformation process in Titanium alloy is controlled optimally by single-chip microcomputer. Its optimization principles and control method are discussed. The hardware and software computer control system is presented. The test results have shown thai the superplasticity in Ti-15-3 Titanium alloy is raised remarkabaly by means of process optimized of superplastic deformation, which is a useable optimal deformation pattern. |
