	4	Grain size altering yielding mechanisms in ultrafine grained high-Mn austenitic steel:Advanced TEM investigations显示文摘The underlying mechanism of discontinuous yielding behavior in an ultrafine-grained(UFG)Fe-31 Mn-3 Al-3 Si(wt.%)austenitic TWIP steel was investigated by the use of advanced TEM technique with taking the plastic deformation mechanisms and their correlation with grains size near the macroscopic yield point into account.Typical yield drop mechanisms such as the dislocation locking by the Cottrell atmosphere due to the presence of interstitial impurities cannot explain the origin of this phenomenon in the UFG high-Mn austenitic TWIP steel.Here,we experimentally revealed that the plastic deformation mechanisms in the early stage of deformation,around the macroscopic yield point,show an obvious association with grain size.More specifically,the main mechanism shifts from the conventional slip in grain interior to twinning nucleated from grain boundaries with decreasing the grain size down to less than 1μm.Our observation indicates that the grain size dependent deformation mechanisms transition is also deeply associated with the discontinuous yielding behavior as it could govern the changes in the grain interior dislocation density of mobile dislocations around the macroscopic yield point.

	12	纳米析出铁素体和贝氏体低碳钢应力应变特性研究显示文摘系统研究了存在纳米尺寸碳化钒析出的铁素体和贝氏体相低碳钢的应力-应变行为。通过奥氏体/铁素体转变并结合相间析出制取组织为铁素体相的试样,通过奥氏体/贝氏体转变,随后进行时效制取贝氏体相试样。两种试样的应力-应变曲线具有几个共同特征:高屈服应力、相对低的加工硬化特性以及足够高的伸长率。根据组织参数计算了溶质原子、晶界、位错和析出物对强度的贡献,并将计算结果与试验测定的应力结果进行对比。溶质原子和晶界强化贡献可以简单地相加,而位错和析出物对强度的贡献大小应表示为两者平方和的平方根。纳米尺寸碳化物在拉伸变形早期阶段可能充当位错增生源的作用,而在变形后期则加速位错湮灭。这种增加型动态回复可能造成铁素体相和贝氏体相这两种钢都具有相当高的伸长率。	Naoya Kamikawa Kensuke Sato Goro Miyamoto Mitsuhiro Murayama Nobuaki Sekido Kaneaki Tsuzaki Tadashi Furuhara	2016	钢铁钒钛2016，37，5：	0
