技術說明

一種具常溫及低溫延展性之高溫耐火合金材料及其製造方法、係將多個具有高熔點之體心立方結構金屬元素如鎢、鉭、鉬、鈮、釩與鉻、與該多個高熔點金屬元素之面心立方結構碳化物進行高溫合金製程，由於該高熔點金屬元素之碳化物能夠溶解進入該高熔點金屬元素內，故能夠將該高熔點金屬元素之體心立方結構，進行晶體結構之改變，使該高熔點金屬元素之合金變成為面心立方結構，因此，當該多個高熔點金屬元素及該多個高熔點金屬元素之碳化物經由高溫熔融或相當之製程如機械合金形成一合金材料後，該合金材料係會具有面心立方結構之晶體結構，因此該合金材料即可方便在常溫進行軋延、鍛造、或其他塑變等後續加工製程。 An elevated refractory alloy material that has ambient- and low-temperature ductility and its manufacturing method are that alloying high-melting point body-centered cubic metal elements, such as W, Ta, Mo, Nb, V, and Cr, with their corresponding face-centered cubic carbides so that these said high-melting point metals can dissolve their corresponding elements, and, consequently, the original body-centered cubic structure of the composed alloy can be changed into face-centered cubic structure. Therefore, after the said high-melting point metal elements and the said carbides are melted together at certain proportion at high temperatures or the like method such as mechanical alloying, and form a final alloy material, the said final alloy can possess face-centered cubic crystal structure. Thereby, the said final alloy material can be further worked at ambient temperature by rolling, forging, and other plastic deformation methods.
