摘要： A duplex strengthened structural steel that is particularly suitable for demanding applications which require both high yield strength and fatigue properties is provided. The preferred steel alloys of this invention are characterized by both the presence of intermetallic strengthening precipitates like maraging steels, as well as alloy carbide strengtheners as is common with secondary hardening steels. Titanium is substantially absent from the preferred steel alloys of this invention. Thus the formation of nonmetallic inclusions, such as titanium carbonitrides, are alleviated which correspondingly enhances the fatigue properties of the preferred alloys. To compensate for the lack of titanium strengthening precipitates within the alloy, additions of aluminum are provided such that the aluminum forms intermetallic strengthening precipitates with nickel.
摘要翻译：提供了特别适用于需要高屈服强度和疲劳性能的要求应用的双相加强结构钢。本发明优选的钢合金的特征在于金属间强化沉淀如马氏体时效钢的存在，以及与二次硬化钢常见的合金碳化物加强剂。本发明优选的钢合金中基本上不存在钛。因此，减少了诸如碳氮化钛之类的非金属夹杂物的形成，这相应地提高了优选合金的疲劳性能。为了补偿合金中缺少钛强化析出物，提供了铝的添加，使得铝与镍形成金属间强化沉淀。

摘要： A secondary hardening alloy steel composition consisting essentially of about 0.25-0.5% carbon, about 0.5-1.0% manganese, about 1.5-3.0% nickel, about 0-1.0% chromium, about 1.75-2.5% molybdenum, about 0-0.4% vanadium, and an additive selected from about 1-3% aluminum and a combination of at least about 1% aluminum and at least about 1% silicon for a combined Al+Si content of about 2-4%, the balance being iron and impurity elements. The present steel composition has the following characteristics: it exhibits a flat tempering response, it is hardenable upon tempering to a Rockwell C hardness of at least 50, and it has an improved combination of hardness vs. toughness properties after tempering in the secondary hardening range. A method of preparation is also described.
