Friction Hydro Pillar Riveting - Alternative Joining Technique for 3.17mm Ti-6Al-4V Sheet

摘要

This paper reports on preliminary results obtained during exploratory research, investigating the feasibility of employing Friction Hydro Pillar Processing principles as an alternative technique for producing riveted joints in 3.17mm Ti-6A1-4V sheets. Influence of process parameters was investigated to understand material flow during the plasticisation phase. An understanding of joint performance from a macrostructural and hardness point of view was established and forms part of the data presented. Process energy was quantified in relation to rotational speed. The data presented will assist in guiding the overall research objective to determine the feasibility of Friction Hydro Pillar Riveting as a suitable alternative high integrity joining process for the Aerospace industry.
