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.
