Figure 1 Coefficients of expansion of INCOLOY alloy 909 and. other high strength alloys,INCOLOY alloy 909,Mechanical Properties. In the age hardened condition INCOLOY alloy 909 has high mechanical properties at room temperature and retains much of. its strength at temperatures to about 1200 F 650 C All mechanical properties reported here are for material given the. standard heat treatment, Solution treat at 1800 F 980 C 1 hr air cool plus age harden at 1325 F 720 C 8 h furnace cool at 100 F 55 C h. to 1150 F 620 C 8 h air cool, Table 5 gives tensile properties of INCOLOY alloy 909 at room temperature and at 1200 F 650 C The effects of. temperatures to 1400 F 760 C on tensile properties are shown in Figure 2 Major decreases in strength do not occur until. temperatures over 1200 F 650 C where age hardening begins to lose its effectiveness. Previously developed low expansion superalloys may be susceptible to grain boundary oxygen embrittlement at high. temperatures and consequent poor notch bar rupture strength Special processing or long over aging heat treatments are. needed to alleviate the problem INCOLOY alloy 909 achieves primarily through its silicon content good notch rupture. properties with conventional processing and heat treatment Typical rupture strength of INCOLOY alloy 909 is shown in. Figure 3 The notch bar tests conducted at 1000 F 540 C showed strength levels comparable to those obtained with. smooth bar tests, An indication of the resistance of INCOLOY alloy 909 to stress accelerated grain boundary oxidation is shown in Figure. 4 which compares creep crack growth rates for INCOLOY alloy 909 and INCOLOY alloy 903 The tests were conducted with. fatigue precracked specimens in air at 1000 F 540 C INCOLOY alloy 903 is another low expansion superalloy similar in. composition to INCOLOY alloy 909, Stress rupture test conditions can greatly affect the measured rupture strengths of low expansion superalloys Alignment.
of the specimen during testing is especially significant. INCOLOY alloy 909 also offers improved low cycle fatigue strength compared to INCOLOY alloy 903 Notched Kt. 2 0 low cycle fatigue tests were conducted in air at 1000 F 540 C at 20 cpm under load control The results shown in Figure. 5 illustrate the vastly improved notched LCF strength of INCOLOY alloy 909. Room temperature mechanical properties of INCOLOY alloy 909 after extended 1000 h exposure to high temperatures. are given in Table 6 The test results indicate that no deleterious phases were formed during the exposure period.

Cycles to Failure, Figure 5 Low cycle fatigue strengths of INCOLOY alloys 909 and. 903 at 1000 F 540 C,INCOLOY alloy 909,Corrosion Resistance. INCOLOY alloy 909 contains no chromium because the. presence of that element would increase thermal expansion. 10 1 rate The absence of chromium however makes the alloy. more susceptible to oxidation in high temperature, atmospheres In some applications INCOLOY alloy 909. may require a protective coating to prevent excessive. oxidation Figure 6 compares INCOLOY alloy 909 with. INCONEL alloy 718 19 chromium in a cyclic oxidation. test at 1200 F 650 C, A characteristic of INCOLOY alloy 909 is that unlike.

1000 F 540 C in air,INCOLOY alloy 909,Fabrication, INCOLOY aloy 909 has good fabricability and can be formed machined and welded by conventional procedures for nickel. alloys In most operations its behavior is similar to that of INCONEL alloy 718. Hot Forming Machining, The temperature range for hot forming of INCOLOY alloy INCOLOY alloy 909 is machined by conventional practices. 909 is 1600 F to 2050 F 870 C to 1120 C The following for high strength nickel alloys The tooling and procedures. sequence is recommended to achieve an optimum given for Group D 2 alloys in the Special Metals publication. combination of tensile and rupture properties Machining on the website www specialmetals com. 1 Initial forging after the metal has been heated to should be used Rough machining should be done with the. 1940 F to 2050 F 1060 C to 1120 C material in the annealed condition. 2 Intermediate forging with 25 reduction after a,heating temperature of 1825 F to 1925 F 995 C to. 1050 C A warm work and reheat sequence at this Welding. stage will produce grain refinement a lower, recrystallization temperature and improved INCOLOY alloy 909 is readily welded by the gas tungsten. properties in the finished product arc process General information on surface preparation. 3 Finish forging with 20 to 25 reduction after a joint design and welding technique is available in the. heating temperature of 1800 F to 1875 F 980 C to publication Joining on the Special Metals website. 1025 C The temperature of the workpiece should www specialmetals com. be lower than 1750 F 955 C during most of the Specific welding recommendations may be obtained. finishing operation from Special Metals,Hot formed material should not be cooled by water.
