摘要：

The influence of B and P in Ni-8-15 mass%Sn and Cu-10-80 mass%Ni-8 mass%Sn alloys was investigated by quantitative metallographic methods. Intragranular precipitation was retarded and cellular precipitation was suppressed by the addition of B and P. The suppressing effect depended upon the Ni concentration in the Cu-Ni-Sn alloys and was large in 40-60%Ni alloys. The suppressing effect of P was larger. B and P segregated at the grain boundary and suppressed nucleation and growth of the cell.
