The microstructure changes in the tempering process of a quenched 6Cr4Mo3Ni2WV Matrix steel have been studied by TEM. Special attention has been paidto the observation of the microstuctures near the peak of the hardness-temperingtemperature curve. It is shown that, the secondary hardening of the steel is main-ly brought about by the precipitation of V_4C_3 and M_2C. With the tempering tempera-ture below 450℃ or so, the cementite lathes precipitated at the twin boundariesand {112} planes are fairly stable. However,...

The microstructure changes in the tempering process of a quenched 6Cr4Mo3Ni2WV Matrix steel have been studied by TEM. Special attention has been paidto the observation of the microstuctures near the peak of the hardness-temperingtemperature curve. It is shown that, the secondary hardening of the steel is main-ly brought about by the precipitation of V_4C_3 and M_2C. With the tempering tempera-ture below 450℃ or so, the cementite lathes precipitated at the twin boundariesand {112} planes are fairly stable. However, they are transformed into a meta-stable phase, and finally are replaced by V_4C_3 M_2C and a new fine cementitewhen the tempering temperature is raised to beyond 500℃ This process certainlyleads to an increase in strength (secondary hardening), and what is more, it leadsto a substantial improvement in impact toughness in the meantime. The best impacttoughness is obtained by the time the cementite lathes are completely trans-formed. When tempering in the range of 600-650℃, the V_4C_3, M_ and alsothe fine cementite coalesced to equiaxed particles-M_6C or Cr_7C_3 at the austeniticgrain and sub-grain boundaries, and the impact toughness of the steel drops ac-cordingly.

用电镜薄膜技术研究了6Cr4Mo3Ni2WV基体钢的淬火和回火态的组织结构,着重观察了硬度-回火温度曲线峰值附近的结构,指出合金的二次硬化主要由V_4C_3和M_2C沉淀产生.回火时沿马氏体内孪晶界和{112}晶面析出的片状渗碳体,低于450℃是稳定的,高于500℃是亚稳相,它在回火过程中转变为V_4C_3,M_2C和新的细化渗碳体,这对二次硬化也有贡献;但更主要的是这种转变使合金的冲击韧性α_K值显著提高.在600—650℃亚稳渗碳体的转变区复合转变为M_6C和Cr_7C_3,同时沿原始奥氏体晶界和亚晶界析出连续的等轴M_6C和Cr_7C_3,这一过程又使α_K值下降.

The correlation of the composition, crystal structure, semiconductivity and catalytic activity for CO oxidation of LaMn1-xCuxO3(0≤x≤1) prepared by citric acid complexing method has been studied. The unique crystalline phase was found to be perovskite within the limits 0≤x≤0.6. It was found that the cell size, activation energy of semiconductivity and catalytic activity changed regularly with the variations of composition and all their maximum values appeared at the same composition region (0.3≤x≤0.4), which is close to the transitional region of rhombohedral symmetry to cubic symmetry. The above results have been discussed in respect to the ionic size, valence state, defect, bond strength and the mechanism of CO oxidation etc.
