Research output: Contribution to journalArticlepeer-review


Planar impact experiments were performed on Ti6Al4V specimens (where the composition is in approximate weight per cent) subjected to different heat treatmetns in order to determine their spall strengths and fracture mechanisms. The technique used was based on recording the spall signal with an embedded manganin stress gauge. The experimental results show that heat treatments can change the spall strengths of this alloy only slightly. The smoothness of spall surfaces depends on the heat treatment through the variations in microstructure. The spalling mechanism consists of void nucleation, growth and coalescence to form dimpled facets (macrovoids) at different levels, which are then connected by shearing. No relation could be found between spall strength and spalling mechanism.
