  • Patent number: 10081856
    Abstract: A method for the practice-oriented, operationally reliable production of castings of an AlCu alloy which consists of Cu:, Mn:, Zr:, Fe:, Si:, Ti:, V:, remainder Al and unavoidable impurities. A melt which has been melted according to this alloy formula is kept at temperature for several hours and then mixed vigorously at least once. Thereafter, the melt is cast in portions into the respective casting which is then solution annealed at temperature for several hours. The casting is quenched from the solution anneal temperature to a maximum temperature of 300° C., at a specified cooling rate which the casting passes through during quenching. The casting is then artificially aged for several hours at 150-300° C. Finally, the casting is cooled to room temperature.

  • Patent number: 10066278
    Abstract: A method for forming an austempered iron composition with a nanoscale microstructure includes a step of heating an iron-carbon-silicon alloy with silicon to a first temperature that is lower than A1 for the iron-carbon-silicon alloy. The iron-carbon-silicon alloy is then adiabatically deformed such that the temperature of the iron-carbon-silicon alloy rises to a second temperature which is sufficient to form proeutectoid ferrite and austenite. The iron-carbon-silicon alloy is cooled to a first austempering temperature. The iron-carbon-silicon alloy is then heated to a second austempering temperature that is greater than the first austempering temperature to form a dual phase microstructure. Characteristically, the dual phase microstructure includes proeutectoid ferrite and ausferrite.

  • Patent number: 10053759
    Abstract: In one aspect, a method of computationally designing a near-? transformation-induced plasticity (TRIP) titanium (Ti) alloy is provided. A thermodynamic database of Ti alloys is created. The data of the thermodynamic database is tailored for martensitic transformations in the Ti alloys near room temperature. Then an overall composite of the near-? TRIP Ti alloy may be obtained by adjusting a reference overall composite of a reference near-? Ti alloy based on the tailored data in the thermodynamic database. In certain embodiments, an annealing temperature of the near-? TRIP Ti alloy may be determined such that a MS?(ct) temperature of the near-? TRIP Ti alloy is about room temperature. In certain embodiments, the near-? TRIP Ti alloy is Ti-8Al-1V-1Sn-1Zr-0.6Mo-0.9Fe-0.1Si-0.1O by weight percentage. In certain embodiments, the near-? TRIP Ti alloy may be cooled at a cooling rate greater than 20° C./min after annealing to inhibit formation of grain-boundary ? (GB-?) phase.
