Abstract In this study, Fire assessment of a fuel tank was done via laboratory experiments and replica test. Laboratory experiments were done on pieces from the tank to simulate the actual fire temperatures and cooling rates. Twelve pieces from the tank were used for the investigations. The samples are subjected to four different temperatures of 1000, 850, 738 and 700 C were tested and cooled in furnace, air and water in each case. All samples after the heating at each of the above-mentioned temperatures and cooling in furnace, air and water were polished to study the microstructure and the hardness. The results showed the suitability of fire assessment via comparisons of the in-situ replica and the laboratory specimens. The results showed that the laboratory and replica microstructures showed no difference or heat damages at 700 C temperature and cooling conditions in air. |
