  • Method for producing a turbine engine part, and resulting mould and intermediate blank
    Patent number: 9969035
    Abstract: The invention relates to a method for producing multiple metal turbine engine parts, comprising steps consisting in: a) casting a metal alloy in a mold in order to produce a blank (3); and b) machining the blank in order to produce the parts, characterized in that the blank obtained by casting is a solid polyhedron having first and second sides (30a, 30b) and third and fourth sides (30c, 30d), in which the third and fourth sides extend between the first and second sides, flaring apart from the first side towards the second side, first at a first angle and subsequently at a second larger angle, and said at least one part is machined in the blank.

  • Method for producing turbine engine parts, and resulting blank and mould
    Patent number: 9844843
    Abstract: The invention relates to a method for producing multiple metal turbine engine parts, comprising steps consisting in: a) casting a metal alloy in a mold in order to produce a blank (3); and b) machining the blank in order to produce the parts, characterized in that the blank obtained by casting is a solid polyhedron with two generally trapezoidal opposing sides (30a, 30b), and the parts are machined in the blank.

  • NICKEL ALLOY
    Publication number: 20140241936
    Abstract: The invention relates to a nickel alloy derived from René 125, but with reduced levels of certain elements (Zr, B, P, S, Si and, to a lesser extent, Ti and Hf) in order to limit the appearance of cracks upon solidification in a moulding process. Specifically, 4.80%?Al?5.00%, 1.48%?Hf?1.52%, 2.28%?Ti?2.33%, 0.005%?B?0.01%, 1.77%?Mo?1.97%, and Zr?0.007%. Other elements can have levels that match those of René 125.
