Increasing phase transformation rate in advanced high strength steel applications
This work has focused on study of the Quenching and Partitioning (Q&P) process by assessing involved mechanisms, microstructure and mechanical properties, aiming at an acceleration of phase transformation rate to shorten the process time in addition to improving properties in service to the industry.

In the first part, this technique has been tested directly after laser welding. Results showed that Q&P not only can reduce the risk of brittle martensite formation after welding but also shortened the post welding treatment time in comparison with regular methods.
In the second part, application of Q&P for bearing steels to evaluate the feasibility, limitations and advantages of this method, has been investigated. The promising results have shown that this method can be applied successfully and save a lot of time, cost and energy.
