  • Patent number: 11548828
    Abstract: A ceramic matrix composite includes a substrate which contains a fibrous body made of silicon carbide fiber, and a matrix which is formed in the substrate, and which contains silicon carbide and a silicon material made of silicon or a binary silicon alloy.
    Type: Grant
    Filed: November 20, 2018
    Date of Patent: January 10, 2023
    Assignee: IHI Corporation
    Inventors: Akihiro Sato, Shingo Kanazawa, Yuuya Nagami, Ryoji Kakiuchi
  • Patent number: 10961161
    Abstract: A production method of a ceramic matrix composite is consisted of: forming a ceramic compact including one or more of a reinforcement fiber and a powder, each including SiC; attaching an ingot of a ternary or more multicomponent Si alloy including Y onto the ceramic compact; and infiltrating the alloy into the ceramic compact by heating up to a temperature at which the alloy melts.
    Type: Grant

  • Patent number: 6966956
    Abstract: A Ni-based single crystal super alloy capable of improving strength by preventing precipitation of a TCP phase at high temperatures may be obtained by a Ni-based single crystal super alloy having a composition consisting of 5.0-7.0 wt % Al, 4.0-8.0 wt % Ta, 2.9-4.5 wt % Mo, 4.0-8.0 wt % W, 3.0-6.0 wt % Re, 0.01-0.50 wt % Hf, 2.0-5.0 wt % Cr, 0.1-15.0 wt % Co and 1.0-4.0 wt % Ru in terms of its weight ratio, with the remainder consisting of Ni and unavoidable impurities. Preferably, the composition of Co in the Ni-based single crystal super alloy is limited to 0.1-9.5 wt %.
