The left chart in Fig. 1 is the new-type continuous air-cooling transformation curves[1] of 25 MnCrNiMo type structural steel.
Fig.1.
Fig. 2, 3 and 4 are established based on air-cooling diameters (see Fig. 1).
The oil and water-cooling diameters of X-coordinate in Fig.1 can be called equivalent diameters.

Results The complete list of experimental results is shown in table 1.
The difference between these two and geometry 1 and 4 is extreme.
Geometry 4 with the symmetric pocket led to a profile with 3870 mm length (vavarage,4 = 7.68 mm/s) and geometry 1 with the asymmetric pockets led to a profile length of 2870 mm (vavarage,1 = 5.7 mm/s).

Quartz glass (15 × 10 × 1 mm) and commercially pure Ti (CP-Ti) (10 × 10 × 1 mm) were used as substrate.
The Rdep increased with increasing Tsub, and showed a maximum value of 1.25 × 10-8 m s-1 for Ca-Ti-O films and 6.0 × 10-9 m s-1 for Ca-P-O films at Tsub = 1073 K.
The Ea of 70 kJ mol-1 for Ca-Ti-O film and 80 kJ mol-1 for Ca-P-O film in the present study can also suggest a chemical reaction limited process in the low Tsub region [11].
