Applying calculation method in alloy design should be an important tendency due to its characters of inexpensive cost, high efficiency and prediction. DOS calculations of AuSn, AsSn and SbSn Sn- based alloys have been investigated by employing DV - Xa method, in which different cluster models were adopted to calculate electron structure.It is proved that some regulations must be taken into ac- count in order to carry out alloy design calculation successfully,which are described in this paper in detail.

腐蚀与防护
采用电化学动电位再活化法（EPR）研究了不同固溶处理和敏化处理状态的304L不锈钢晶间腐蚀行为。结果表明，EPR法可灵敏并定量评价304L不锈钢的晶间腐蚀敏感性；测量时，推荐采用1．0mol／L H2SO4＋0．1mol／L KSCN混合溶液；304L晶间腐蚀敏化度随固溶处理时间的延长而减小，随敏化处理时间的延长而增大。
