Definitions

This invention relates to multiphase nickel base alloys, particularly to one having a unique combination of greatly improved strength below about 1700D F., coupled with high strength at 1700-1800 F.
FIG. 1 is a graphical comparison of some tensile strength properties of the alloy of this invention, designated as S15, with the strongest commercially available alloys;
FIG. 2 is a graphical comparison of the 0.2% yield strength properties of the alloy of this invention, designated as S-IS, with the strongest commercially lavailable alloys;
FIG. 3 is a graphical comparison of stress rupture properties of the alloy of this invention, designated as S15, with the strongest commercially available alloys.
alloying elements and their ranges have been carefully selected to provide an improved a-lloy of unexpected strength properties particularly in the range below 1700 F. while maintaining a high strength level between 1700- 1800 F.
Ni3(Al, Ti) In order to obtain maximum strength characteristics in a nickel base alloy including the elements Ti and Al, it would ybe desirable to include as much Al and Ti as possible to form Ni3(Al, Ti). However there is a composition limitation. In order to obtain high temperature strength between 1700-1800 F. without regard to other properties in other ranges, the Al ordinarily should be about 2 to 31/2 times the Ti content. It the Ti is increased at the expense of Al, lower temperature strength is gained but at a loss of higher temperature strength. This was recognized by notingvthat the solution temperature of Ni3(Al, Ti) was higher with higher Al/Ti ratios. Also it has been recognized that if the Ti content is below 1.5%, lower temperature strength is lost. For example, referring to FIGS.
Al/Ti ratio is high.
lt is also to be noted how the low temperature strength is less than the alloy of this invention. The same reduction in properties can be seen in lthe stress rupture comparison of FIG. 3. Both effects are due to the high Al/ Ti ratios in Alloy A.
the stress rupture strengths are represented by the comparison of stress with a time-temperature parameter shown at the horizontal coordinate.
Ni3(Al, Ti) is required in the careful and critical balance of the elements of the alloy of this invention.
the formulae listed above are important features of this invention in view of the fact that the Ti level is maintained within the range of 1.5 +4%. If the nickel content is less than that given by the formulae, the phase NiAl may be formed in preference to Ni3(Al, Ti) with a consequent great loss in medium and elevated temperature properties.
the element cobalt which aids in ductility, has been added within the range of 7-16 weight percent. It wouldl the proper balance of elements, the range has been SetV at 7-l6 weight percent. A higher percentage would bek included at a sacrice of the nickel content thus to form less Nis (Al, Ti) for precipitation hardening; a lower percentage does not have a signicant effect on ductility. At Al and Ti levels lower than that of the alloy of this invention an addition of higher percentages of cobalt is possible, but the unique characteristics of this alloy is lost.
the chromium included in the alloy has its principal eiect as an aid to oxidation resistance. It has been found that a minimum of 8 weight percent is required to improve the oxidation resistance. However if chromium is increased to too high a level, for example as high as 20 weight percent or more, the chromium is added at lthe expense of nickel and it drops the nickel below the minimum essential inthe above listed formula. ThereforeV it is essential to balance the chromium and cobtalt content with the required amount of nickel. Because more cobalt is required for ductility purposes, the chromium content is maintained as low as possible in order to be able to allow the addition of more cobalt without detracting trom the nickel content. In addition, high levels of chromium favor formation of sigma phase which causes great loss of ductility.
MBC carbide is a high molybdenum carbide stable to higher temperatures and is not dissolved until about 2150 F.
the low molybdenum M23C6 carbide is soluble in the 19004950o F. temperature range and would be formed with lower molybdenum and higher chromium.
lt is the intention of the alloy of this invention to form the higher molybdenum, lower chromium MGC carbide.
molybdenum is added at the expense of nickel. No real advantage has been found in adding higher molybdenum percentages although some strengthening is achieved from higher percentages of molybdenum in some solution hardening type of alloys.
the ⁇ solution hardening value of molybdenum reaches the maximum at about 4-5 weight percent; however it is the intention of this alloy to include molybdenum at higher levels to assure the formation of MSC carbide.
MggCG may form (less than 5.5% Mo) the same as in Alloy B shown in the drawing and having a nominal composition, by weight, of 4.5% Al, 3.5% Ti, 18% Co, 15% Cr, 4.5% Mo, 0.12% C, 0.01% B, balance Ni.
Alloy B shown in the drawing and having a nominal composition, by weight, of 4.5% Al, 3.5% Ti, 18% Co, 15% Cr, 4.5% Mo, 0.12% C, 0.01% B, balance Ni.
Tungsten has been included in the alloy of this invention within the range of l-3 weight percent because it has been recognized that the properties of nickel base material can be increased by such an addition. However below 1% no appreciable improvement was recognized. Although the elements W and Mo are sometimes considered equivalent from a solution hardening point of view, the substitution of l-3 weight percent molybdenum for the 1 3 weight percent tungsten does not have the same effect on the alloy of this invention as does the tungsten inclusion. Molybdenum and tungsten act individually in this case, las would be expected on a theoretical basis. Over 3 weight percent W does not further improve properties, but merely decreases ductility.
Columbium is included in the alloy of this invention, because in addition to being a solution hardener, it is a more successful carbide former than titanium. This means that columbium rather than titanium will selectively form car-bides with the carbon thus the titanium is free for the more important action in the Ni3(Al, Ti). Thus the alloy of this invention obtains a double benefit from the inclusion of columbium.
the inclusion of above 2 weight percent columbium within the range of the alloy of this invention begins to embrittle the ralloy by too much solution hardening.
columbium may also form an Ni3Cb precipitation hardening phase which has a lower solution temperature than does the Ni3(Al, Ti). Therefore the columbium range for the alloy of this invention is maintained below 2% to avoid displacement of Al and Ti from the Ni3(Al, Ti).
the element boron has been included in nickel base lalloys of this type, a particular and critical minimum amount has been recognized. At least 0.003 weight percent boron must be included in wrought materials to help prevent carbide precipitation in the grain boundary by performing relatively low melting phases in the grain boundary. Somewhat more, about 0.006 weight percent boron is required in cast alloys. However, above about 0.4 weight percent there is too great an amount of low melting phase formed in the grain boundary which results in a weak material.
the alloy of this invention has been provided a nickel base alloy of improved low temperature strength up to about 1700 F. compared with the best available commercial alloy-s.
the alloy of this invention has at least the same high temperature stress rupture properties available in alloys of this type.
