Definitions

  • the invention relates to a state of the art, such as that found in Young-Won Kim, High-Temperature Ordered Intermetallic Alloys IV, "Recent Advances in Gamma Titanium Aluminide Alloys", Symposium Nov. 27-30, 1990, Boston, Measure USA (MRS Proc. Vol. 213, pp. 777-794).
  • Material produced using the method according to the invention certainly has a better strength than a correspondingly produced material based on a coarse powder (alloy Ti48Al3Cr), but without mixing with the fine-grained powder (alloy Ti48Al2Cr2Nb), if the proportion of coarse-grained powder is at least 5- times and at most 100 times the proportion of fine-grained powder in percent by weight.
  • a particularly good strength is obtained when the proportion of coarse-grained powder is about 7 to 20 times, preferably 10 times, the proportion of fine-grained powder in percent by weight.
  • Correspondingly good values were also determined for the creep behavior at temperatures around 700 to 800 ° C.
