alloying element (【技】为获得具有某些性能的合金而有意识添加于某金属中的其他金属或非金属的统称。: ① Carbon is the significant alloying element in steel and, in general, strength increases but toughness decreases with increasing carbon content. 碳是钢中重要的合金元素。一般而言，随着含碳量的增加，钢的强度提高，而韧性降低。② In such cases greater toughness is obtained by adding small amounts of alloying elements, including manganese, nickel, chromium, molybdenum, niobium and vanadium, individually or in combination, generally in the range of 0 per cent. 1. 0.02 ~ 在这种情况下，提高钢的韧性可以通过添加一种或几种少量的合金元素，例如锰、镍、铬钼、铌、钒等获得，通常情况下添加量为 0.02% ~ 1.0%。); alloy element (①The hardness, toughness and resistance to wear and corrosion of steels can be modified by adding alloy elements, special production processes and heat treatment. 钢的硬度、韧性和耐磨损及耐腐蚀性能可以通过添加合金元素、采用特种生产工艺以及热处理得以改善。② Alloy elements, chemical elements other than carbon, are usually metallic and deliberately added to steel for the purpose of inducing special properties. 合金元素，除碳之外，通常为金属元素，是为使钢具有特殊性能，而有意加人钢中的化学元素。) |
