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 shortens the post welding treatment time compared to 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.
