硬化

The microstructure of hardened layer and formation mechanism were investigated.The microstructure of hardened layer consist of the completely hardened region and the transition region.The completely hardening region is composed of fine acicular martensites,residual austenites and a few dot-like carbonides.From surface to bottom in the hardened layer,the microstructure varies from fine to coar...

结果表明：采用适当的磨削参数可满足该钢所要求的淬火温度，进而获得适宜的淬硬层显微硬度和强化层深度；磨削淬火层由完全硬化区和过渡区组成；完全硬化区主要由细小针状马氏体组成，从表面到里层，组织形貌呈现&细→粗→细&的变化规律，其形成机理是热-力耦合作用影响磨削淬火过程中的奥氏体晶粒大小及其位错密度，并将直接影响转变后的马氏体组织形貌。

During the brightening, the hardened layer should be removed as little as possible because the thickness of plasma carburized layer is only less than 50 μm.

由于不锈钢离子渗碳后的硬化层厚度仅为50μm左右，所以在亮化处理过程中应尽可能减少硬化层的减薄量。

Moreover, in order to make clear whether IV infection touches off the cause and its pathogenesis of artherosclerosis inflammatory reaction. The study also uses IV of type A1 and A3 to infect repeatedly Jimpy mice with E gene defect, to observe AS histology change of Jimpy mice aorta and detect the change of IV antibody and inflammatory reaction medium (eg.TNF-α, IL-1) in Jimpy mice serum and express of monocyte chemotactic factor( MCF-1) and nuclear factor kB in Jimpy mice aorta tissue .

另外，为了弄清流感病毒感染是否是触发动脉粥样硬化炎症反应的发生原因及其机理，本研究还用A1、A3型流感病毒反复感染载脂蛋白E基因缺陷小鼠，观察小鼠主动脉的动脉粥样硬化组织学改变，并检测小鼠血清中流感病毒抗体、炎症反应介质（如TNF-a、IL-1等）变化情况以及小鼠主动脉组织中的单核细胞趋化因子-1（MCP-1）和核转录因子kB表达情况。

After overloading,△ε should be estimated with Hook's law,(2) The quantitative expression of FCIL considering overloading effect are firstly developed for Al-alloy and LAHS steel.

据此提出，对于连续应变硬化材料，FCI超载效应较大，而非连续应变硬化材料的FCI超载效应很小。

Composite and technology of preparing, brushing, stoving of the coatings was determinedby the experiment, composite and technology of preparing, moulding, curing of sodium silicate bonded sand cured by organic ester was also determined too,then the foundry technology test of sleeve made from high chromium cast iron was done.
