Nondestructive material reliability evaluation for Cu-alloy of combustion chamber

Abstract

The aim of this research is to evaluate high temperature damage of combustion chamber made of Cu-Cr-Zr alloy using eddy current testing (ECT) techniques based on AMR sensor. The cracks in a simulated combustion chamber can be detected by multi-frequency ECT technique. Also the relative conductivity of damaged copper alloy specimens both at room temperature during tensile testing and at high temperature of fatigue and creep testing were related to the applied damage with micro cracks.
