The character of SCC in austenitic stainless steels has been investigated by means of SEM. According to the testing conditions, three kinds of typical micro-features, namely, striation-like markings, river-like patterns, and fan-like patterns were observed from the SCC fracture surface. From the above observation results, it can be concluded that the fracture surface and the direction of SCC propagation possess certain crystallographic character. The atomoc model of crystal lattice was used to explain the formation...

This paper deals with the influence of prestressing on sub-structures and relaxation ability of springs made of 50CrVA oil-tempering wires(OTW) and mechanical heat treating wires (MHTW). Experimental results show that TEM structures of both springs after hot prestressing are tempered lathmartensite. Its main characteristics are black lalternating with white, approximately parallel sub-cells, in which the white strips are alloying ferrite and the fine, narrow black strips are cell walls of sub-structure with...

This paper deals with the influence of prestressing on sub-structures and relaxation ability of springs made of 50CrVA oil-tempering wires(OTW) and mechanical heat treating wires (MHTW). Experimental results show that TEM structures of both springs after hot prestressing are tempered lathmartensite. Its main characteristics are black lalternating with white, approximately parallel sub-cells, in which the white strips are alloying ferrite and the fine, narrow black strips are cell walls of sub-structure with high density of dislocation tangles. The cementite particles are scattered in the black cell walls. On the other hand, after hot or electric prestressing there are more black and dislocation tangles crowding together in the cell sub-structures of MHTW springs than in OTW springs, and in individual areas appear some sub-structures like twined martensite.Before prestressing the stress relaxation of 50CrVA springs at low temperatures consists in general of two stages, but after hot or electric prestressing appears only the second stage. The general equation of stress relaxation curves based on the regression method is ΔP/P_0=a+blnt_R. The loss rate of load (ΔP/P_0)_(10) of both spring is below 2% in 10 years.The stress relaxation process of spring at low temperatures is a combined effect of recovery and dynamic recovery, and it takes place mainly in weaker micro-regions of some sub-grains. The important affecting factors are homogeneity and stability of the sub-structure.

本文研究了强压处理对50C_rVA油淬火钢丝及形变热处理们丝弹簧的组织结构及松弛性能的影响。结果表明,经热或电强压处理后TEM组织是回火板条马氏体,其主要特征是:在某些晶粒微区内出现了黑白相间、大致平行的条状亚结构,其中白条为合金铁素体,窄细条是高位错密度缠结的胞壁,碳化物质点主要分布在胞壁内。形变热处理者有数量较多、黑色密集位错缠结的胞状组织,局部也有类似孪晶的亚结构。未强压时弹簧的低温应力松弛过程一般分为两阶假;经热或电强压处理后只出现松弛的第二阶段。回归直线方程通式为ΔP/P_0=a+blntR,算出两类弹簧工作十年后的负荷损失率<2%。弹簧的低温应力松弛是一个回复和动态回复的综合效应,它在某些晶粒较弱的微区内优先进行。组织和亚结构的均匀稳定是主要影响因素

Four new high manganese steels and their simple, efficient dispersion treatments were developed by improved design of composition and adding SR modification agent. The microstructre, mechanical properties, work-hardening and wear-resistance were investigated systematically. The deformation induced martensite transformation were carried out using X-ray diffraction and TEM. The result show that the as-cast microscructure of the new kinds of steels consists of fine austenite grains, perlite grains and spheroidal carbides. However, the microstructure of dispersion treated steels became solid solution hardened by fine austenite and dispersed spheroidal carbides. Under certain deformation condition the parallel slrapslike ε-martensite and vermicular α-martensite can be obtained. The mechanical properties and capability of work hardening are superior to high manganese steels. The wear-resistance of the dispersion treated steels is 1-3 times higher than high manganese steels, meanwhile the cost of production was decreased by over 20 %. Therefore, the aim of increasing the wear-resistance of high marganese steels was efficiently and economically fulfilled.
