Steam turbine blade, method of manufacturing the same, steam turbine power generating plant and low pressure steam turbine |
| abstract |
There is provided a steam turbine blade made of Ti-base alloy comprising an α+β type phase in which a difference of a tensile strength is small between a blade portion and a dovetail portion, a tensile strength at a room temperature of the dovetail portion is equal to or more than 100 kg/mm 2 and a suitable toughness is commonly provided together with a strength, as a steam turbine blade having a length of 43 inch or more, a method of manufacturing the same, a steam turbine power generating plant and a low pressure steam turbine. In the steam turbine blade having a blade portion and a plurality of fork type dovetails, wherein the blade is made of Ti-base alloy structured such that a length of the blade portion is equal to or more than 52 inches with respect to a rotational speed 3000 rpm of the blade or equal to or more than 43 inches with respect to the rotational speed 3600 rpm, and a tensile strength at a room temperature of the dovetail is equal to or more than 100 kg/mm 2 , preferably equal to or more than 110 kg/mm 2 and equal to or more than 96% of the tensile strength at the room temperature of the blade portion. |
