... of ASTM B409. The average hardness of the undamaged and damaged sleeve material measured in the laboratory using a Vickers hardness tester was found to be 174 HV 3 and 170 HV 3 which is within the range specified in ASTM B 409 UNS N08800 for plate material. It was also observed that at the mid...
