摘要：

?칭템퍼링시에발생하는, 재료의길이방향의열처리치수변동을경감할수 있는냉간공구재료를제공한다. 열간가공에의해연신되어, 탄화물을포함하는어닐링조직을갖고, ?칭템퍼링되어사용되는냉간공구재료에있어서, 이냉간공구재료의상기한열간가공에의한연신방향과평행한단면의어닐링조직중, 연신직각방향에수직인단면의어닐링조직에서관찰되는원 상당직경이 5.0㎛이상인탄화물의, 하기 (1) 식으로구해지는탄화물배향도 Oc의표준편차가 6.0 이상인냉간공구재료이다.단, D는탄화물의원 상당직경(㎛)을, θ는탄화물의근사타원에있어서의장축과상기의연신방향이이루는각도(rad)를각각나타낸다. 그리고, 상기의냉간공구재료를사용한냉간공구와, 그제조방법이다.

摘要（中）：

本发明提供一种能够缓和淬火时产生的材料的长度方向的热处理尺寸的偏差的冷作工具材料。通过热加工拉伸的，具有退火组织，其包括硬质合金，？在寒冷的工具材料被称为回火时，在上述平行于由冷工具材料的热加工的横截面拉伸方向的退火组织，在横截面中的退火组织观察垂直于直角拉伸方向碳化物至少当量圆直径5.0㎛的，以下的（1）冷工具具有6.0度由以下公式确定的碳化物的Oc的取向的一个标准偏差的材料。然而，碳化物d是代表当量直径（㎛），θ表示长轴和角度（弧度）是碳化物的近似椭圆的分别成形，延伸的方向。然后，使用上述冷工具材料的冷工具及其制造方法。

摘要（英）：

?? provides a cold tool material that can be called to reduce the heat treatment dimensional fluctuation in the longitudinal direction of the material produced at the time of tempering. In the cold tool material that is stretched by hot working, annealing used has a tissue comprising a carbide, a ?? is called tempering, annealing of the organization of a cross section parallel with the one stretching direction by the hot working of the cold tool material a cold tool material than the standard deviation of the carbide of the carbide which is not less than the degree of orientation Oc circle equivalent diameter 5.0㎛ observed in the annealed structure of a cross section perpendicular, calculated by the following equation (1) 6.0 to draw a perpendicular direction.

However, D is the circle equivalent diameter (㎛) of the carbide, θ represents the major axis and the angle (rad) is the extending direction of the forming of the approximated ellipse of the carbide, respectively. Then, the cold-tool utilizing the tool of the cold material, a method of manufacturing the same.
