摘要：

Analytical and numerical models of linear friction welding of Ti6Al4V (numbers indicate wt.%) are established to predict temperature rises during the initial phase of the process. which is of importance in forming sound welds. Both model predictions are compared with experimental data. The numerical model is used to explain the physical conditions that control the ability to weld under certain process conditions. The effects of the exothermic reaction of titanium with oxygen during the extrusion phase are also discussed. (C) 2000 Elsevier Science S.A. All rights reserved.
