Dynamic fracture toughness and charpy transition properties of a service-exposed 2.25Cr-1No reheater header pipe
Article Abstract:
The evaluation of the dynamic fracture toughness and Charpy transition properties of a 16 mm thick 2.25Cr-1Moreheater header pipe exposed at 813 K for 120,000 h by instrumented impact test (IIT) is presented. The method presented for estimating dynamic fracture toughness from IIT of Charpy specimens give reliably conservative results without the need for precracking.

Modeling studies to predict stresses in composite floor tubes of black liquor recovery boilers
Article Abstract:
The results of finite element modeling studies undertaken to make an analysis of the composite floor tubes of recovery boilers used by the pulp and paper industry are presented. The results indicate that the stresses in the tubes can be determined with the help of the mismatch in the coefficient of thermal expansion between the carbon steel and the clad material.

Improvement of vibration damping capacity and fracture toughness in composite laminates by the use of polymeric interleaves
Article Abstract:
The type of multifunctionality in composite laminates that involves the functions of structural vibration damping and delamination resistance is focused. Polymeric interleaves can be used between the composite laminae to simultaneously improve the vibration damping capacity and interlaminar fracture toughness in composite laminates.
