1 The average decarburization time is 20 minutes and the average treatment time is 29 minutes.

2 The results show that both are caused by decarburization in heat tret - ment.

3 In niobium alloy containing carbon occurs decarburization in case of contamination by oxygen at higher temperature.

4 The RH process control model includes static decarburization model, dynamic decarburization model, temperature model, alloy minimum cost model, and composition prediction model.

5 Decarburization shall be determined by microscopic examination as described in BS 6617 : Part 1.

6 Is hardness tested on a surface that has been ground to remove decarburization?

7 The effect of rare - earth elements to prevent oxidation and decarburization heat treating salt bathshas been discussed.

8 There is tight ( or thin and highly adherent ) scale and decarburization, at least in certain areas.

9 A new dynamic mathematical model to represent the processes of decarburization and degassing in RH vacuum refining units were developed.

10 Therefore, based on these experiments, it can be deduced that the transfer ability of electron in slag phase is of great importance to decarburization reaction at low carbon level.

11 Its solution depends mainly on the solution circulation pump ( Decarburization large pump ) to provide.

12 As with AOD, the benefit of using PMS is that the decarburization end-point can be more accurately determined.

13 Quenching crack propagation characteristics of the organizations on both sides without decarburization phenomenon significant difference between crack and materials and forging cracks.
