英文高手請進 ((20點))

拜託~請幫幫我翻成中文~請不要用翻譯機...因為有專業名詞~翻起來會很怪 >_<

The durability of a tool is a function of many parameters including mechanical and physical properties of the tool material, the nature and parameters of the forming process,

and properties of the material to be formed. In aluminium extrusion, dies suffer complex stress conditions and high temperatures, and consequently, the properties of the die material play a significant role in ensuring the durability of a certain tool [1]. Currently, H-13 tool steel is applied as a die material for aluminium extrusion. In most cases, two

factors limit the lifetime of a die: severe wear in the region of the bearing channel and fracturing in stress concentration areas, the mechanism of which is related to cyclic softening [2]. While wear of the bearing surfaces can be prevented by applying surface hardening techniques, a material possessing higher fatigue resistance should be used to avoid fatigue cracking. In this connection, superalloys are being examined as candidate die materials for aluminium extrusion. For example, it is known that Nimonic alloy PK 37 produced by Norsk Specialmetall AS is successfully used as a material for die inserts in the extrusion of copper and aluminium bronze, resulting in longer lifetime of the tool.

    (註:為了讓閱讀方便,我全用中文寫,有可能需要標示英文術語地方我有用特別顏色,你滑鼠指標浮過這些字你會看到英文提示)模具的耐用度有很多的因素,

    包括模具材料的機械與物理的特性,成型過程的本質與變數,

    還有要成型的材料的特性。在鋁壓出中,

    印模遭受複雜的

    應力狀態與高溫,因此,印模材料的特性在保證一個模具的耐用度上扮演很重要的角色[1]。

    目前,H-13 tool steel (H13 模具鋼)有被應用為鋁壓出的印模材料。在大部份情況,有兩個因素限制著印模壽命:在

    軸承道周圍的嚴重磨損與

    應力集中區的破壞,而這機制與循環軟化有關 [2]。

    軸承面的磨損可以用表面硬化技巧來預防,

    而要預防疲勞裂開則應用有更高的疲勞破裂阻力的材料。因應這關聯,超耐熱合金正受考慮做為鋁壓出的印模材料。舉例來講,我們知道 Norsk

    Specialmetall AS 所製的 Nimonic alloy PK 37 合金被已被成功的用來做銅與鋁青銅的壓出的公模,延伸模具的壽命。

    The durability of a tool is a function of many parameters including mechanical and physical properties of the tool material, the nature and parameters of the forming process, and properties of the material to be formed.

    一件工具的耐用程度取決於所使用的材料,它本身的機械性質及物理性質、成形過程受到影響的變數,以及被成形的材質之特性。

    In aluminium extrusion, dies suffer complex stress conditions and high temperatures, and consequently, the properties of the die material play a significant role in ensuring the durability of a certain tool

    鋁擠成型在擠製過程中,其模具將承受高溫及複雜的壓力情況,因此擠製用的模具所採用的材質拌演一項重要的角色,在以確保其工具成形後的耐用性。

    [1]. Currently, H-13 tool steel is applied as a die material for aluminium extrusion. In most cases, two factors limit the lifetime of a die: severe wear in the region of the bearing channel and fracturing in stress concentration areas, the mechanism of which is related to cyclic softening

    目前,H-13工具鋼普遍被應用於鋁擠成型,影響模具的壽命有2個因素: 容器筒間的嚴重摩擦,以及高壓集中區域的破裂韌性,也就是機械性質中的循環軟化度。

    [2]. While wear of the bearing surfaces can be prevented by applying surface hardening techniques, a material possessing higher fatigue resistance should be used to avoid fatigue cracking.

    當表面硬化處理技術的應用可避免容器筒間的嚴重摩擦同時,耐好的抗疲乏材料也應列入考慮,以防止疲乏斷裂。

    In this connection, super alloys are being examined as candidate die materials for aluminium extrusion. For example, it is known that Nimonic alloy PK 37 produced by Norsk Special metal AS is successfully used as a material for die inserts in the extrusion of copper and aluminium bronze, resulting in longer lifetime of the tool.

    這個2種技術的結合,超合金被使用者當作測試鋁擠成型的材質,例如: 由Norsk Special metal As(特殊金屬製造廠)製造的PK37鎳基合金被成功的應用在擠型模具上的材質,以擠壓成型方式製作出青銅、铝、及紅銅等材質的工具,提昇工具的使用壽命。

    工具的耐久性是許多因素的作用, 包括工具材料的機械特性和物質特性、製造成形過程的本質和其他的因素, 和製造材料的特性。

    在壓製鋁的時侯, 模具會遭受複雜的加壓狀況和高溫, 因而模具材料的特性在保證某一工具的耐久性上扮演一個重大的角色[ 1 ] 。

    當前, H-13 工具鋼被應用在壓製鋁的模具材料。在大部分情況下, 二個因素限制了模具的壽命: 在軸承通道區的嚴重磨損因素和在集中加壓區的斷裂因素, 也就是機械性質中的循環軟化[ 2 ] 。

    雖然軸承表面的磨損可由表面硬化技術而防止, 但是材料擁有的更高的抗勞性應該用來避免金屬疲勞崩裂。

    有了這層關系, 超合金被認為是適合用在壓製鋁的模具材料。例如, Nimonic特殊金屬廠製造出知名的PK 37 鎳合金被成功的應用在壓製銅和鋁銅過程中,注入沖模的材料, 造成工具更長的使用壽命。
