Definitions

  • the melting point of aluminum is low in general and typically the heat resistance is not necessarily sufficient. As such, in order to conduct the expanding use as described above, the heat resistance of aluminum alloy must be improved. From such viewpoints, various proposals for aluminum alloys have been made, which include the descriptions relevant to the following patent literature, for example.
  • Such a raw material is subjected to heat treatment, plastic working, hot plastic working or other appropriate treatment thereby to result in that Zr and Ti having been solid-solved in supersaturated state finely precipitate as an Al-(Zr, Ti) series intermetallic compound phase.
  • hot plastic working (working process) is efficiently performed because capable of both the feature creating and precipitating the second compound phase at the same time.
  • Tensile test was performed for a test piece cutout from each sample, and strength and ductility at room temperature and strength at 300 degrees C (no pre-heating) were measured. Results thereof are shown together in Table 1. Note that the tensile test was performed in compliance with JIS Z2241, each strength shown in Table 1 is a breaking strength, and each ductility is a percentage elongation of distance between reference points from the time of starting test to the time of breaking.
