The samples with the size of 50mm×13mm×1.5mm were cut from two type of steel materials.
The results of the corrosion rates of the two materials under different temperatures are shown in Fig. 3.
By changing CO2 partial pressures, the corresponding corrosion rates of the two materials are plotted in Fig. 6.
Fig.7 shows the corrosion morphology of the two materials under different carbon dioxide concentration at 200℃.
It shows that the two materials still uniformly corroded in a carbon dioxide environment.

Materials and methods The experimental program was carried out at the Civil Engineering laboratory of University of Minho and involved the characterisation of 8 low cost meshes made of different materials and 9 mortars with different compositions.
The particle size distribution of the earth based mortars and constituent materials is given in Fig. 2.
Hydraulic lime was chosen, since this binder is expectedly more compatible with earthen materials.

Materials The materials used in this study were two duplex (AISI 2205 grade) stainless steels, supplied by Roldán S.A.
Shot peened bars of both materials designated D2205hsp (hot ribbed) and D2205csp (cold ribbed) were also tested.
The different values for the stress amplitude used were established taking into account previous studies conducted with these same materials [6].
