In Situ Electrochemical Behavior of Titanium Alloys (T40, T64) Under 4 He 2+ Irradiation

Abstract : The (α+β)‐ (T64) and a‐titanium (T40) alloys are considered as good candidates materials for primary component circuit of mobile or stationary nuclear power plant owing to their advantageous combination of properties, i.e. low elasticity modulus, high resistance to impact loading, high strength, low density and low thermal expansion coefficient. 4He2+ irradiation has been performed on titanium alloys in water at the ARRONAX cyclotron (66.5MeV) up to a dose of 70kGy at room temperature. This work describes water radiolysis effects on titanium alloys by structural studies (XRD, SEM). It also shows an in situ electrochemical study of titanium alloys behaviors (under 4He2+ irradiation) with corrosion rate determination. Two different behaviors were observed, a decrease of corrosion rate for T40 (>200nm/y for 40kGy) and an increase for T64 (up to 1.2μm/y for 25kGy).
