1226374 五、發明說明（1) 【發明所屬之技術領域】 本發明是關於一種多元合金，特別是關於一種可在高 溫使用之高強度多元合金。 【先前技術】 所謂的合金是指「一種金屬和另一種或者一種以上的 金屬或非金屬互相融合，而具有金屬的各種性質之物 質」。由兩種成分混合製成的合金稱為兩元合金，同理， 由多種成分混合的合金成之為多元合金。傳統上實用合金 系統的開發，皆以一至兩種元素為主要組成元素，以鐵元 素為主，即為一般的鋼鐵材料，如合金鋼、工具鋼和高速 鋼等。或以銘元素為主，則為發展相當成熟之铭合金。廣 泛使用於各領域之超合金材料，則有鐵基合金、鈷基合 金、錄基合金之分。上述之合金成份，主成分的元素皆佔 合金組成原子百分比的4 0 %以上，再依不同的特性需求， 加入其他的輔助元素。 上述之合金設計理念顯然限制了合金成分的自由度， 勢必也會限制合金性能的發展。目前使用於高溫環境的合 金，其種類常依使用溫度高低來選擇，例如碳鋼或低合金 鋼適合使用於攝氏3 7 0度以下、耐熱不銹鋼則通常使用於 攝氏4 2 5度以下。原因為此類合金的強度會隨著溫度升高 而快速劣化，尤其溫度超過攝氏5 0 0度時，其降伏強度大 多低於2 0 0 MPa，而造成使用上的諸多限制。另一種常使用 於高溫者為超合金，超合金可使用於攝氏540度以上，在 一定溫度範圍内，超合金的強度可隨溫度升高不會劣化，1226374 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a multicomponent alloy, and particularly to a high-strength multicomponent alloy that can be used at high temperatures. [Prior art] The so-called alloy refers to "a metal and another or more than one metal or non-metal are fused with each other and have the various properties of the metal". An alloy made of a mixture of two components is called a binary alloy. In the same way, an alloy made of a mixture of multiple components is a multicomponent alloy. Traditionally, the development of practical alloy systems has one or two elements as the main constituent elements, and iron elements as the main components, which are general steel materials, such as alloy steel, tool steel, and high-speed steel. Or the main element is Ming, which is a fairly mature Ming alloy. Superalloy materials widely used in various fields include iron-based alloys, cobalt-based alloys, and base-based alloys. In the above alloy composition, the main component elements all account for more than 40% of the alloy composition atomic percentage, and other auxiliary elements are added according to different characteristics. The above-mentioned alloy design concept obviously limits the degree of freedom of the alloy composition, and will certainly limit the development of alloy properties. At present, the types of alloys used in high temperature environments are often selected according to the use temperature. For example, carbon steel or low alloy steel is suitable for use below 370 ° C, and heat-resistant stainless steel is usually used below 425 ° C. The reason is that the strength of such alloys will deteriorate rapidly with increasing temperature, especially when the temperature exceeds 500 degrees Celsius, its drop strength is much lower than 200 MPa, which causes many restrictions on use. Another type often used at high temperatures is superalloys. Superalloys can be used above 540 degrees Celsius. In a certain temperature range, the strength of superalloys will not deteriorate with temperature.

1226374 五、發明說明（2) 常使用之超合金有鎳基和钻基兩類，其中鎳基超合金被廣 泛應用於需要高強度的高溫元件合金，鈷基合金在攝氏 73 0度至11 00度的條件下，仍具有一定的高溫強度。這類 合金經鍛造處理其降伏強度在攝氏8 0 0度可維持在40 0Mpa 以上。超合金的合金設計理念還是「以單一元素為主要組 成元素」，其主要組成元素，如錄或始，含量約為4 5 %至 7 5 % ，並且再添加絡、始、鎳、鉬、鎢、銳、銘、鈦、 鐵、錳、矽、碳、硼、鍅和釩等6至1 0種次元素來進行改 質’使其能夠增進各種性能以達到南溫使用的目的。這種 以單一元素為主的合金設計思考方式，所可能產生的組合 及發展已到了相當成熟的階段，如欲再提昇其高溫性質亦 很難再有所突破。 【發明内容】 為了製造具有優良高溫使用性質的合金，本發明提供 一種由多種元素所組合而成的高強度多元合金，其跳脫了 傳統合金設計架構，多元合金所包含的每一種主要元素分 別佔總組成的5 %至3 5 %原子百分比，同時高強度多元合 金在高溫下具有高強度的特性。 為達上述目的，本發明之高強度多元合金係以鐵、 I古、錄、鉻、銅和銘作為主要元素，其中，每一種元素分 別佔合金總組成的5 %至3 5 %原子百分比。並且，經過實 際的測試證明，高強度多元合金在高溫下具有優異的高強 度性質。多元合金提供了合金設計上更大的自由度，同時 其成分比例可以針對所需之各種不同性質來加以調整和改1226374 V. Description of the invention (2) Nickel-based and diamond-based superalloys are commonly used. Nickel-based superalloys are widely used in high-temperature component alloys that require high strength. Cobalt-based alloys range from 7300 to 1100 ° C. Under the conditions of temperature, it still has a certain high temperature strength. After forging, this type of alloy can maintain a drop strength of more than 400 MPa at 800 degrees Celsius. The alloy design concept of superalloys is still "with a single element as the main constituent element". Its main constituent elements, such as recording or starting, contain about 45% to 75%, and further add complexes, starting, nickel, molybdenum, tungsten , Sharp, Ming, Titanium, Iron, Manganese, Silicon, Carbon, Boron, Samarium and Vanadium, etc., to be modified by 6 to 10 kinds of sub-elements. This kind of single-element-based design thinking of alloys, the possible combination and development has reached a fairly mature stage, and it is difficult to make further breakthroughs if you want to further improve its high temperature properties. [Summary of the Invention] In order to manufacture an alloy with excellent high-temperature use properties, the present invention provides a high-strength multi-component alloy composed of a variety of elements, which breaks away from the traditional alloy design framework. It accounts for 5 to 35 atomic percent of the total composition. At the same time, high strength multicomponent alloys have high strength characteristics at high temperatures. In order to achieve the above object, the high-strength multi-component alloy of the present invention uses iron, iron, copper, chromium, copper, and metal as the main elements. Among them, each element accounts for 5 to 35 atomic percent of the total composition of the alloy. Moreover, after actual tests, the high-strength multicomponent alloy has excellent high-strength properties at high temperatures. Multiple alloys provide greater freedom in alloy design, and their composition ratios can be adjusted and modified for various different properties required
