| Abstract: | Based on the center-temperature curves of the 7050 aluminum alloy specimen recorded during its cryogenic treatment, surface heat transfer coefficient of specimen during its cryogenic treatment is solved by means of inverse heat conduction method. Temperature field of 7050 aluminum alloy during its cryogenic treatment is calculated with ANSYS program .The obtained center-temperature curve are compared with experimental ones with a good agreement between them. The results also show that temperature field and the heat-transfer are non-linear. |
