Magnesium alloys have a high mechanical rigidity and an extremely low density. They attract car manufacturers to meet the standards US EPA CAFE (Corporate Average Fuel Economy), and to replace many materials, such as copper alloys, cast irons and steels, and also aluminum alloys. Recently, mechanical and thermal properties of magnesium alloys with rare earth elements and Zn have been studied in scientific...
In this work we have developed a model to determine the thermal effusivity of the defects that occur in steel. We used a non-destructive pulsed thermography to know the thermal properties of defects, which need certain industrial sectors. On the basis of a solution of the heat equation in one dimension, and using the finite element method; we calculated by simulation the surface temperatures of defective...
The infrared thermography technique developed in the present study was successfully applied to determine the scale thicknesses in the steel pipe. By finite element method we have calculated the infected pipe surface temperature. We have developed a model for estimation the thickness scale on the inner surfaces pipe. Pipe dimensions and scale layer are taken as geometrical parameter. We have studied...
