Description
니켈-베이스 합금(Nickel-base alloy)이 열기관(예를 들면 연소 엔진, 고정 가스터빈, 돌고있는 가스터빈)에 널리 사용되고 있는 것은 잘 알려져 있다. 왜냐하면 니켈-베이스 합금은 700 - 900 ℃의 온도범위에서 견고성이 아주 뛰어나기 때문이다.It is well known that nickel-base alloys are widely used in heat engines (eg combustion engines, stationary gas turbines, spinning gas turbines). This is because nickel-based alloys are very robust in the temperature range of 700-900 ° C.
상기 합금들의 다수는, 700 - 900 ℃의 온도범위에서 견고성 강화를 위해 결정적인 γ′와 γ″상들을 많이 갖고 있다. γ′와 γ″상들의 석출을 위해 주로 합금요소로 알루미늄, 티타늄, 탄탈륨 그리고 니오븀이 사용된다.Many of these alloys have many γ 'and γ ″ phases that are critical for enhanced robustness in the temperature range of 700-900 ° C. Aluminum, titanium, tantalum and niobium are mainly used as alloying elements for the deposition of γ 'and γ ″ phases.
예를 들면 GB-A 929,687은 니켈-크롬-코발트-몰리브덴 합금을 설명하고 있는데 상기 합금에는 2,0 - 3,5 % 티타늄, 0 - 0,8 % 알루미늄 그리고 2 - 5,25 % 니오븀이 첨가되어 γ′와 γ″의 석출을 통해 견고성이 현저히 강화된다.For example, GB-A 929,687 describes a nickel-chromium-cobalt-molybdenum alloy, which contains 2,0-3,5% titanium, 0-0,8% aluminum and 2-5,25% niobium. Firmness is remarkably enhanced by the precipitation of γ 'and γ ″.
이때, 텅스텐은 몰리브덴의 치환요소로서 10 원자 % 까지 허용되며 탄탈륨은 니오븀의 치환요소로서 3 무게 % 까지 추천된다.At this time, tungsten is allowed up to 10 atomic% as the substitution element of molybdenum and tantalum is recommended up to 3 weight% as the substitution element of niobium.
GB-A 1,036,179는 철은 합금요소로서 더 이상 허용되지 않는 것은 예외로 하고, 기본적으로 GB-A 929,687에 제시된 요소들의 한계(limit)만을 설명하고 있다.GB-A 1,036,179 basically describes only the limits of the elements set out in GB-A 929,687, with the exception that iron is no longer allowed as an alloying element.
US-A 4,981,644에서도 니켈-크롬-코발트-몰리브덴 합금이 설명되어 있다. 상기 합금은 티타늄, 알루미늄, 니오븀 그리고 탄탈륨에 의해 석출이 강화되지만 레늄, 몰리브덴, 텅스텐 요소에 관해서는 단지 1,0 - 8,5 %의 총 함유량을 정하고 있다.Nickel-chromium-cobalt-molybdenum alloys are also described in US Pat. No. 4,981,644. The alloy is strengthened by titanium, aluminum, niobium and tantalum, but defines a total content of only 1,0-8,5% for rhenium, molybdenum and tungsten elements.
WO-A 90/03450은 석출을 강화하는 합금을 설명하고 있다. 상기 합금에서는 US-A 4,981,644와 비교하여 볼때, 석출을 강화하는 요소들인 알루미늄(Al), 티타늄(Ti), 니오븀(Nb), 탄탈륨(Ta)를 위해 상한계(upper limit) 뿐만 아니라 하한계(under limit)도 제시된다. 이에 반해 레늄, 하프늄, 바나늄은 단지 상한계만 조절된다.WO-A 90/03450 describes alloys that enhance precipitation. Compared to US Pat. No. 4,981,644, the alloy has not only upper and lower limits for aluminum (Al), titanium (Ti), niobium (Nb) and tantalum (Ta). under limit) is also presented. In contrast, rhenium, hafnium and vananium only have upper limits controlled.
내열성이 높은 합금을 단련 합금(wrought alloy)으로도 사용하기 위하여(예를 들면 내열성이 높은 합금을 변형이 되고 접합될 수 있는 얇은 금속판으로 사용하기 위하여) 혼합크리스탈 강화 합금을 형성하였다. 상기 혼합크리스탈 강화 합금은 예를 들어 알루미늄, 티타늄, 니오븀과 같은 단지 약 2 무게 % 의 석출강화 요소들을 포함한다.Mixed crystal-reinforced alloys were formed to use high heat resistant alloys as wrought alloys (e.g., to use high heat resistant alloys as thin metal plates that can be deformed and bonded). The mixed crystal reinforced alloy contains only about 2% by weight of precipitation hardening elements such as, for example, aluminum, titanium, niobium.
GB-A 1,336,409는 니켈-크롬-코발트-몰리브덴 합금을 설명하고 있다. 상기 니켈-크롬-코발트-몰리브덴 합금에서는 석출강화 요소들인 알루미늄과 티타늄의 합계가 0,8 - 2,1 %로 제한되어 있다.GB-A 1,336,409 describes nickel-chromium-cobalt-molybdenum alloys. In the nickel-chromium-cobalt-molybdenum alloy, the sum of precipitation hardening elements aluminum and titanium is limited to 0,8-2,1%.
US-A 4,877,461에는 대략 비슷한 수준에서 즉, 0,5 - 2,25 % 에서, 하지만 5% 까지의 텅스텐을 첨가한, 크리이프 강도(creep strength)가 향상된 니켈-크롬-몰리브덴-코발트 합금이 설명되어 있다.US-A 4,877,461 describes nickel-chromium-molybdenum-cobalt alloys with improved creep strength at approximately comparable levels, i.e. 0,5-2,25% but with up to 5% tungsten. have.
EP-B 0633 325에는 니켈-크롬-코발트-몰리브덴 합금을 위한 US-A 4,877,461을 근거로 하면서, 알루미늄과 티타늄을 0.5 - 2.0 무게 % 로 제한하고 최대 5 무게 % 텅스텐, 0.7 - 2.5 무게 % 탄탈륨을 첨가한 합금이 공지되어 있다. 상기 합금은 견고성을 위해 유리한 것으로 증명이 되었다.EP-B 0633 325 is based on US-A 4,877,461 for nickel-chromium-cobalt-molybdenum alloys, limiting aluminum and titanium to 0.5-2.0 weight% and up to 5 weight% tungsten, 0.7-2.5 weight% tantalum. Added alloys are known. The alloy proved to be advantageous for robustness.
알루미늄과 티타늄을 0.5 - 2.0 무게 % 로 낮추고 니켈-크롬-코발트-몰리브덴 합금에 텅스텐과 탄탈륨을 첨가함으로써 변형과 접합이 가능한 내열성의 함석 공업재료를 제조하는 것은 가능해 졌지만, 이때 획득한 내열성은 석출강화 합금의 내열성보다 훨씬 뒤처진다.By lowering aluminum and titanium to 0.5-2.0 weight% and adding tungsten and tantalum to nickel-chromium-cobalt-molybdenum alloys, it became possible to produce heat-resistant tin-containing industrial materials that can be deformed and bonded. Much lagging behind the heat resistance of the alloy.
본 발명은 오스테나이트(austenitic)계 니켈-크롬-코발트-몰리브덴-텅스텐 합금에 관한 것이다.The present invention relates to an austenitic nickel-chromium-cobalt-molybdenum-tungsten alloy.
도 1 내지 4는 700℃, 750 ℃, 800 ℃, 850 ℃에서 공지의 합금과 본 발명에 따른 합금의 응력-파열 시험(stress-rupture test)의 결과를 도시한 도면이다.1 to 4 show the results of a stress-rupture test of known alloys and alloys according to the invention at 700 ° C., 750 ° C., 800 ° C. and 850 ° C. FIG.
따라서 본 발명의 과제는, 충분한 산화 저항력에서 내열성과 크리이프 강도를 위한 값들을 개선시켜 물체들의 수명이 현저히 길어지는 니켈-크롬-코발트-몰리브덴 합금을 형성하는 데에 있다. 공업재료는 변형과 용접이 가능한 단련 합금으로서 사용할 수 있어야 한다.It is therefore an object of the present invention to form a nickel-chromium-cobalt-molybdenum alloy, which improves the values for heat resistance and creep strength at sufficient oxidation resistance, which significantly lengthens the life of the objects. Industrial materials shall be available as annealed alloys capable of deformation and welding.

특히 바람직한 오스테나이트계 니켈-크롬-코발트-몰리브덴-텅스텐 합금은(질량 %) 다음과 같은 구성을 갖고 있다:Particularly preferred austenitic nickel-chromium-cobalt-molybdenum-tungsten alloys (mass%) have the following configuration:
탄소: 0.05 내지 0.10 %Carbon: 0.05 to 0.10%
크롬: 21 내지 23 %Chromium: 21-23%

용해과정에서 불가피하게 야기된 불순물들 포함Contains impurities inevitably caused during dissolution
본 발명에 따른 니켈-크롬-코발트-몰리브덴-텅스텐 합금은 종래기술과는 달리 텅스텐의 함유량이 5 질량 % 보다 훨씬 많으며, 내열성과 크리이프 강도를 개선하기 위해 탄탈륨을 첨가하지 않는다. 또한, 0.01 에서 0.10 질량 % 까지의 이트륨을 혼합하는 것은 순환적 산화(cyclic oxidation) 저항력을 향상시킨다.The nickel-chromium-cobalt-molybdenum-tungsten alloy according to the present invention, unlike the prior art, contains much more than 5% by mass of tungsten and does not add tantalum to improve heat resistance and creep strength. In addition, mixing of yttrium from 0.01 to 0.10 mass% improves cyclic oxidation resistance.
탄탈륨을 아주 적게 첨가하고 5 질량 % 까지만의 텅스텐을 첨가한 합금은 혼합 크리스탈 강화에 의해 이루어져야 하는 견고성 퍼텐셜(potential)을 다 이용하지는 않는다. 따라서, 놀랍게도 US-A 4,877,461과 EP-B 0633 325의 내용과는 달리 5 % 이상의 텅스텐 함유량이 견고성 향상을 위해 아주 좋다는 것이 밝혀졌다.Alloys with very little tantalum and up to 5% by mass of tungsten do not fully utilize the robust potential that must be achieved by mixed crystal strengthening. Thus, surprisingly, in contrast to the contents of US Pat. No. 4,877,461 and EP-B 0633 325, it was found that a tungsten content of more than 5% is very good for improving the robustness.
하지만 텅스텐의 첨가는 8.0 무게 % 로 제한된다. 왜냐하면 함유량이 높아지면 온간 가단성(warm malleability)이 주어지지 않기 때문이다.However, the addition of tungsten is limited to 8.0% by weight. Because higher content does not give warm malleability.
본 발명에 따른 니켈-크롬-코발트-몰리브덴-텅스텐 합금은 700 - 900 ℃의온도범위에서 뛰어난 크리이프 강도를 갖기 때문에 특히 다음과 같은 물체에 적합하다:Nickel-chromium-cobalt-molybdenum-tungsten alloys according to the invention have excellent creep strength in the temperature range of 700-900 ° C. and therefore are particularly suitable for the following objects:

상기에 언급한 물체들은 본 발명에 따른 공업재료로 쉽게 제조할 수 있다. 왜냐하면 상기 공업재료는 온간(warm) 연성이 좋을 뿐만 아니라 냉간 가공과정(예를 들면, 얇은 부피에 대한 냉간 압연, 모를 없애기, 프레스 가공에서 골이 지게 하기, 가장자리를 꺾어 구부리기)을 위해 필요한 변형능력을 갖고 있기 때문이다.The above-mentioned objects can be easily produced from the industrial material according to the present invention. Because the industrial material not only has good warm ductility, but also the deformation capacity required for cold working processes (e.g. cold rolling to thin volumes, stripping, corrugation in press work, bending edges). Because it has.
상기 공업재료들은 용접에 좋기 때문에 큰 구성요소들을 접합하는 것도 아무런 문제가 없다.Since the industrial materials are good for welding, there is no problem in joining large components.
도 1 내지 4에 도시된 바와 같이 응력-파열 시험(stress-rupture test)에서 700℃, 750 ℃, 800 ℃, 850 ℃ 에서 이루어진 수명을 근거로 하여, 공지기술에 따른 합금 5 내지 7 보다 본 발명에 따른 합금 1 내지 4이 훨씬 우수한 것을 나타낸다.1 to 4 according to the prior art, based on the service life at 700 ℃, 750 ℃, 800 ℃, 850 ℃ in the stress-rupture test (shown in Figures 1 to 4) It shows that alloys 1 to 4 according to this are much superior.
합금 1 내지 7의 구성은 표 1에 나타나 있다.The configurations of alloys 1-7 are shown in Table 1.
순환적 산화 저항력에 대한 텅스텐의 부정적인 영향을 상쇄하기 위해서 뿐만 아니라 순환적 산화 저항력을 훨씬 좋게 하기 위해, 본 발명에 따른 합금에 이트륨이 혼합된다. 본 발명에 따라, 현저한 향상 효과를 위해 절대적으로 필요한 이트륨의 최소 함유량은 0.01 % 이며, 최대 함유량은 0.10 %로 정해져 있다. 상기 최대 함유량을 초과하면 순환적 산화 저항력이 나빠지게 된다.Yttrium is mixed in the alloy according to the invention not only to counteract the negative effect of tungsten on cyclic oxidation resistance but also to make the cyclic oxidation resistance much better. According to the present invention, the minimum content of yttrium which is absolutely necessary for the remarkable improvement effect is 0.01%, and the maximum content is set at 0.10%. When the maximum content is exceeded, the cyclic oxidation resistance becomes poor.
이트륨의 긍정적인 효과는 도 5와 도 6의 순환적 산화시험에서 700 ℃ 와 800 ℃에서 1000 시간 이상의 시험시간 이상에서 나타나는 아주 적은 질량증가를 통해 증명된다.The positive effect of yttrium is demonstrated in the cyclic oxidation tests of FIGS. 5 and 6 with very small mass gains over 1000 hours of test time at 700 ° C and 800 ° C.
