The relations between the non-equilibrium segregation process of P and the change of the texture in Fe-P alloys have been studied by analytical electron microscope and orientation distribution function.It was shown that P segregated preferentialy on the{110}slip planes, the P segregation structures with repeating cycle a=1.582 nm form at 450℃.<001>// ND direction abated.<111>//ND direction heightened.And{111}<110>has a tendancy to transform into{111}<143>texture in recovering process.{111}<143>direction trans- forms into{111}<112>direction after recrystalizing.A model to describe the effects of non-equilibrium segregation structures of P on orientation change was proposed and em- ployed to interpret the experiment results.

Investigation was made of the sputtering rate in glow discharge lamp with relaion to constituent of 25 different specimens of 6 binary systems.namely,Cr-Fe,Bi-Sb,Cu-Zn, Ag-Cu,Al-Zn and Cd-Sn.by measuring mass loss sfter each sputtering under constant Ar pressure and voltage applicd.The correlation.in general,between sputtering rate and concentration of constituent of these non-intermetallic binary alloys obeys the hyperbolic law under steady state,that may be approximately regarded as linear correlation only on certain special condition if the two components of the alloys with similar sputte ringrates.

Glow discharge cathodic sputtering of alloys containing second phase precipitates or injected oxide particles has been observed with energy dispersive X-ray spectrometer and scanning electron microprobe.It was shown that the formation of cones during the sputtering in these alloys is due to masking of the matrix by glow sputtering second phase precipitates or oxide particles.At steady state,the density of cottes were found to be a function of the densities pre- cipitates or oxide particles in bulk alloy.In addition to the changes of local sputtering rate,the electrostatic effect may play a role on the formation fo cones.
