Beschreibung
Zusammenfassung:	The application provides a thermal treatment method of Y7 aerofoil girder profiles. The method comprises the step of carrying out quenching treatment on Y7 aerofoil girder profiles. Temperature of the quenching treatment is 490-510 DEG C, and heat preservation time of the quenching treatment is 300-350 min. As the Y7 aerofoil girder profiles are special-shaped profiles and the maximum wall thickness is large, three-dimensional mechanical property of the Y7 aerofoil girder profiles is stable and high by optimizing quenching temperature and quenching time of the thermal treatment method.
