摘要:

鈦及鈦合金材料因具有密度小、比強度高、韌性好、無磁性、耐腐蝕性好等優異的綜合性能,在航空、航天、艦船、核電等重要領域及石油、冶金、化工、電力、生物醫學等民用市場有著廣泛的應用。系統闡述了鈦及鈦合金材料的優越性能及廣泛應用，對比分析了近10年來海綿鈦、電解鎳、電解銅、不銹鋼等原材料價格變化趨勢及規律，分析了實現鈦及鈦合金低成本化新的加工方式。利用全壽命經濟性分析的方法，對不銹鋼、銅合金、鎳基合金、鈦及鈦合金在艦艇冷凝管道應用實例的對比分析及不同材料設備經濟綜合性分析，提出了在現有原材料價格、原料產量、加工成本、產品產量的條件下，應大力推廣應用鈦及鈦合金材料。

Abstract:

Because of excellent comprehensive properties, such as low density, high specific strength, good toughness, non-magnetic, excellent anti-corrosion, titanium and titanium alloys were widely used in aviation, aerospace, naval vessel petroleum, metallurgy, chemical industry, electric power, biomedicine and other civil markets. This paper describes the advantages and applications of the titanium and titanium alloy materials，comparatively analyzes the changes of the raw materials prices in recent years, such as titanium sponge, electrolytic nickel, copper alloy and stainless steel, and analyzes the processing pathways to achieve low cost of titanium alloy. Through calculating and analyzing the examples of titanium alloys applications by the life-cycle economic analysis method, the economical efficiency was analyzed about condensate water pipings for naval vessels made by stainless steel, copper alloy, nickel alloy, titanium and titanium alloy. Under the recent conditions in raw materials prices, materials production and processing cost, we should vigorously promote the using of titanium and titanium alloy materials.
