帽构件及其制造方法
摘要：
帽构件(1)包括：顶面部(13)、第1棱线(113)以及两个侧壁(11)。两个侧壁(11)的中央硬度Dc为300HV以上。两个侧壁(11)分别具有软化部(L)和与软化部(L)相邻接的强度过渡部(T)。软化部(L)的硬度Dn比中央硬度Dc低至少8％(Dc-Dn≥0.08Dc)。强度过渡部(T)设于从软化部(L)向一端去0.5mm以上的范围。强度过渡部(T)的硬度Dt在比中央硬度Dc低8％～1％的范围过渡(0.92Dc≤Dt≤0.99Dc)。帽构件(1)还具备两条第2棱线(114)和两个凸缘(14)。
摘要（英）：

A hat member (1) is provided with a top surface part (13), a first ridgeline part (113), and two sidewalls (11). The two sidewalls (11) have a center hardness Dc of 300HV or greater. Each of the two sidewalls (11) has a soft part (L) and a strength transition part (T) adjoining the soft part (L). Hardness Dn of the soft part (L) is less than the center hardness Dc at least by 8% (Dc-Dn>=0.08 Dc).The strength transition part (T) is disposed in a range of 0.5 mm or greater from the soft part (L) toward one end. Hardness Dt of the strength transition part (T) changes in a hardness range from 8%to 1% less than the center hardness Dc(0.92Dc<=Dt<=0.99Dc). The hat member (1) is further provided with two second ridgeline parts (114) and two flanges (14).
