A New Technique for Testing Dynamic Tensile Behavior of Metals at Elevated Temperatures 2005-01-1414

A high-temperature tensile impact experimental technique, based on a rapid-contact heating method, is developed to test specimen at temperatures up to 1073K. High-strain-rate tensile responses of commercially pure titanium at elevated temperature are investigated. The testing results show that the yield stress and ultimate tensile stress all decrease with increasing temperature, while the fracture strain decreases with increasing temperature at the temperature range 25 °C<t<350 °C, and increases with increasing temperature t>350 °C.
