The purpose of the present article is to make an initial study of themorphology of the upper bainite of 0.55 pet C-Si-Mn-Mo steel,The resultsare obtained through various test methods,such as optical microscope,x-raydiffraction,scanning and transmission electron microscopes,and compact tensiontest.The transformation during tempering affects the mechanical properties ofthe said steel.According to the results of the tests,the said medium carbon alloy steel,after being austenitized at 900℃ for half an hour and cooled in air,showsan upper bainite structure composed of ferrite and 30~35% austenite richin carbon forming parallel interlaced layers,As shown by the simple dilatometermeasurements,when the temperieg tmeperature reaches about 400℃,themicrostructure of the steel contains ferrite,carbide and 5% austenite.Theauthors suggest the name for such a structure-“tempered bainite.”It isfound that the rate of propagation of cracks,da/dN,increases with the increaseof the tempering temperature,maximum value being reached at about 400℃.Scanning electron microscope examination shows that the fractured surfaceschanges from the quasi-cleavage type to the cleavage type.

本文初步讨论的问题:通过光学显微镜、X 射线衍射、电子显微镜(透射和扫描电镜)、紧凑拉伸等试验方法研究了55 SiMnMo 钢在正火状态下的上贝氏体形态,以及回火转变对其机械性能的影响。根据试验,在中碳合金钢中经900℃0.5小时奥氏体化后空冷所出现的上贝氏体由铁素体和30~35%富碳奥氏体片层相间组成。经简易膨胀仪测定,析出碳化物的回火转变温度约为400℃,此时金相组织变为由铁素体、碳化物和5%奥氏体组成,作者称这种形态为回火贝氏体。在发生回火转变时,裂纹扩展速率(da/dN)随回火温度增加而增加,在400℃时达最大值;断口的扫描电子金相从准解理型过渡到解理型。

The quasi-cleavage fracture has been studied in conjunction with the stress

本文试图探讨准解理断裂的本质。联系多晶材料的典型应力一应变曲线,对不同钢的断裂韧度试样的断口分析表明,准解理断裂可以看作是一种过渡的断裂机制。首先,一系列微观解理裂纹在高拉伸应力集中地方生核,然后这些裂纹各自沿着它本身已变形晶粒的解理面上扩展,最后借助于微观塑性聚合方式,这些微裂纹彼此连接。根据上述断裂模型可以认为:解理裂纹与塑性变形间的相互作用是准解理断裂的一种重要性质。借助于断口定量分析方法,有可能把断口形貌和一些力学参数间关系建立起来。

The fracture surfaces of certain fracture toughness specimens have been ex-amined by SEM. With materials fractured in quasi-cleavage mechanism, the meandistance, ξ, from the pre-crack tip to the site where the quasi-cleavage crackstarts is regarded to be a characteristic parameter. It seems that this related toG_(Ic) and can be used as an important parameter characterizing the stress field ofthe plastic zone.

利用扫描电镜对一些断裂韧性试样的断口表面进行了观察.发现:对于遵从准解理机制开裂的材料,从预制裂纹顶端到其前缘的初始准解理开裂源的平均距离ξ是一个特征参数,它不仅与断裂韧度G_(Ic)有学,而且是塑性区应力场的一个重要参量.
