为了弄清韧性奥氏织构对钢铁的影响，研究了具有较强{L}和全部织构成分的奥氏纯铁的力学行为。结果表明，织构对冲击性能有显著影响，平行于断口的{L Oa}组分越强，冲击/冲击转变温度越高。织构样品中Oj单位裂纹路径Lc与晶粒度1a之比大于先前研究中得到的比Oj约2。结果表明，单位裂纹率比晶粒度更能反映组织对材料性能的影响。坚韧的OJ熨斗。讨论了织构试件与随机试件的断口形貌、单位裂纹/板条的差异。本文研究了拉伸试验中的延伸率和宽度的缩减率，以及各向异性是如何由所确定的尺寸引起的，而强度是如何受织构的影响的。
To clarify the e./fect oj texture on the toughness oj iron and steels, mechanical behaviors oj pure irons having a strong { l Oa} < all > textllre component were investigated. It is revealed that the texture has a notable influence on the Charpy impact /lroperties; the stronger the { l Oa} component parallel to the frac ture surface, the higher the im/lact transition temperature. The ratio oj unit crack path lc to grain size la in the textured sample is larger than the ratio oj about 2 obtained in the previous study. It can be coneluded that the unit crack Ilath is more reasonable than the grain size as a characteristic oj the structure affecting on th. toughness oj irons. The difference oj the Jractographic appearance oj unit crack /lath between the textured sample and the random one is discussed. The elongation and the reduction in width in tensile test -,how the /llanar anisotropy due to the priferred orimtatiolls, while the strengtlt is /Wt influenced by the texture under the eX/lerimell tal conditions oj tltis study.
