The effect of different microstructures of steel 30CrMnSiNi2A on the susceptibility of cadmium embrittlement has been studied and compared under the unique yield strength level. The results show that the tempered martensite exhibits the maximum susceptibility to cadmium embrittlement,while the lower bainite shows the minimum susceptibility.The mixed microstructure of the above two has a susceptibility in between.

The reaction kinetie model for the synthesis of ultrafine TiN powder from vapour phase sys- tem TiCl_4-NH_3-H_2-N_2 in the high frequency plasma reactor was proposed as follows: 1/V((dn_(TiCl_4))/dt)=0.852e~(-63.2·RT)P_(TiCl_4) The majority of factors influenced upon the reaction rate were analysed,so as to provide the theoretical basis for improving quality of TiN powder and for optimizing the design of plasma reactor.

The effects of stress components on nucleation sites and propagation directions of stress cor- rosion cracks in brass were investigated with specimens under mode Ⅱ and mode Ⅲ loadings. The results indicated that under mode Ⅱ loading,stress corrosion cracks nucleated on the site with maximum normal stress component and propagated along the plane perpendieular to the maximum normal stress,under mode Ⅲ loading,the stress corrosion crack was not evident on the 45°plane due to the general corrosion in aqueous solution with high NH_4OH concentra- tion,while stress corroded in aqueous solution with low NH_4OH concentration, numerous cracks with spacings of 10—150μm were found on the 45°plane with maximum normal stress and no stress corrosion cracks was observed on the plane with maximum shear stress.
