2.1 Strengthening Mechanism and Features of
“NANOHITEN”
NANOHITEN (NANO: New Application of Nano
Obstacles for Dislocation Movement) is a type of high
tensile strength steel which satisfi es both the abovementioned
hole expansionability and elongation requirements.
In this innovative product, the steel sheet is
strengthened using precipitates refi ned to single nanometer
size. Its features are as follows.
(1) Single phase microstructure using ferrite with excellent
formability as the matrix.
(2) Strengthening by precipitates refi ned to single nanometer
size.
(3) Extremely high thermal stability of precipitates.
(4) Due to the extremely large strength increment achieved
by precipitation hardening, it is possible to avoid use
of Si as a solid solution hardening element.
A schematic diagram of the effect of the microstructure
on the balance of elongation and hole expansionability
is shown in Fi

2.1强化机理及特点
“ NANOHITEN ”
NANOHITEN （纳米：新应用纳米
障碍脱位运动）是一种高
拉伸强度钢satisfi上述两个胚胎
孔expansionability和伸长率的要求。
在这种创新的产品，钢板
加强沉淀再融资内使用单一纳米
大小。其特点如下。
（ 1 ）单相铁素体显微结构与良好的使用
成形的矩阵。
（ 2 ）加强再融资的析出单一纳米医学
大小。
（ 3 ）极高的热稳定性的沉淀物。
（ 4 ）由于非常大的力量实现增量
沉淀硬化，有可能避免使用
硅作为固溶强化元素。
示意图效果的微观结构
平衡伸长和空穴expansionability
图所示。 1 。多阶段，如
铁素体+马氏体（女+男） ，高伸长率，获得
而孔expansionability低;相反，与
单相微结构，如单相贝氏体
钢铁，洞expansionability高，而伸长率为
低的。注意到高伸长和高铁
孔expansionability单相组织，
在NANOHITEN ，洞expansionability提高
同时保持高伸长用铁素体
单相组织。然而，与传统的
方法，这是不容易实现强度为780兆帕斯卡或
较高的单相铁素体钢。
图2显示的结果计算
之间的关系数额沉淀和
增量沉淀硬化常规
沉淀硬化钢与沉淀了
尺寸为10纳米， 1纳米，假定奥罗万，比
mechanism2 ） 。由于强度增量决心
由间隔析出的影响
沉淀物的大小随沉淀内容。
举例来说，当碳量的TiC颗粒沉淀
为0.08 ％ ，大规模，有可能实现降水
硬化了700兆帕如果大小的沉淀物
再融资内为1纳米。在此基础上，其目的在NANOHITEN
是要最大限度地沉淀硬化
再融资的效果宁沉淀单一纳米
