Kinetics of Strain Aging Behavior of API 5L X65 and API 5L B Steel Types on Long-Term Operations
The kinetics of strain aging behavior of API 5L X65 and API 5L B steel types on long-term operations were studied. Pre-strain was applied to the two steel types and the process was continued with the aging process at various temperatures and over various time periods. Mechanical properties data...

| description | The kinetics of strain
aging behavior of API 5L X65 and API 5L B steel types on long-term operations
were studied. Pre-strain was applied to the two steel types and the process was
continued with the aging process at various temperatures and over various time
periods. Mechanical properties data were used to determine activation energy
levels. The results showed that API 5L B steel has a lower activation energy
level than API 5L X65 steel through the identification of yield strength value,
which is 13.7 kJ compared to 24.87 kJ, which means that API 5L B steel is more
susceptible to strain aging than API 5L X65 steel. Predictions of long-term
mechanical properties which are verified through tensile testing showed that
the appropriate parameters to observe and predict the strain-aging behavior are
implemented by evaluating the changes in yield strength, which gives the
minimum value for the average margin of error for API 5L X65 steel and API 5L B
steel, i.e. 0.3% and 0.45%, respectively. On the other hand, prediction value
parameters, such as elongation, toughness and the Vickers hardness have an
average margin of error range between 2.6 to 5.06%. |
