| Abstract Scope |
An iron-chromium-aluminum (FeCrAl) Kanthal® APMT alloy is one of the candidate cladding material for water reactors to serve as a substitute for zirconium-based alloys with enhanced accident tolerance and improved high-temperature properties along with oxidation/corrosion resistance. In this study, serrated yielding behavior resulting from the dynamic strain aging (DSA) of FeCrAl APMT alloy is investigated over the temperature range (298 – 973 K) and strain rates [10^(-3)-10^(-5) sec^(-1)] using uniaxial tensile tests followed by microstructure examinations for the as-received and deformed samples. Temperature and strain rate effects on tensile properties and serration types are evaluated along with critical strains for serrated flow. |
