We aim to continue the same success in 2021. I would like to briefly talk about what we have done in terms of digital conversion in this process. First of all, with the consultancy of my dear teacher, my dear friend Dr. Lütfi Apillioğlu, we started the lean trans- formation, which is an indispensable part of digital transformation. By demolishing the walls between the departments in our factory, we eliminated the silo logic in our com- pany. We have taken very important steps in terms of reducing our costs by reducing waste in every area, we invested in a warehouse system that can integrate into a digital system that makes vertical storage in- stead of our manual warehouse system that covers a lot of space, we got rid of unnecessary stocks. In the name of digitalization in production, we started to use our Product Data Management (PDM) system more effectively, we invested in the Project Management System MANAGE software, which can be integrated into our design system. When the integration is completed, we will be able Dear Readers, to plan our workflows much more effectively, track re- In order to communicate better with you, we pub- al-time engineering studies and project revisions, and lished the first issue of our magazine in July 2020, make significant improvements in our delivery times. under the conditions of the new type of Corona I would like to thank Armada company, which made Virus epidemic that left its mark on 2020 and put the us come a long way in the adaptation of MANAGE whole world in great uncertainty. software to our company in a short time.

Introduction Regarding to the rapid development in aviation industry, the components of the system requires high tem- perature and pressure endurance during its service life. For this reason, thermo-physical properties and the creep-rupture characteristics of the components strongly depend on the microstructure of the alloy [1]. In order to achieve precise control- ling of the process, fine grains, and homogenous microstructure, the se- lection of the heat treatment method is important [2].
