Navy C-Ring test parts were made of AISI 1022, 4320, 8625, and CF8M steels and heat treated in a designed experiment to evaluate the commercial heat treatment distortion simulation software DANTE. The parts were machined and then measured with a CMM for original dimensions. The parts were then heated and subsequently quenched in two different immersion orientations in agitated water. Temperatur...

Assessment of creep damage and residual creep life of a cast HP 40 Nb Mod. Reformer tube was performed, wherein the experimental Larson–Miller diagram and area fraction of creep voids were adopted. The state of damage of the tube in service was metallographically analyzed by using light and electron microscopy. Samples from the serviced reformer furnace tube were cut and prepared for void exami...

Hypereutectic High Chromium Cast Iron (HHCCI) is a new type of corrosion-wear-resistant material developed from ordinary high chromium cast iron by increasing the and carbon content often used in abrasive environments where wear corrosion interact. The resistance HHCCI related to number, size, shape distribution carbides microstructure matrix. This paper reviews research progress improving vari...

S. Rešković, I. Jandrlić, University of Zagreb, Faculty of Metallurgy, Sisak, Croatia, F. Vodopivec Institute of Metals and Technology, Ljubljana, Slovenia Using thermal imaging camera during tensile testing of low carbon and Nb microalloyed steel influence of testing rate on start of plastic deformation was investigated. The results showed that the onset of plastic flow is significantly differ...
