The grain boundary character distribution(GBCD) optimization and its effect on the intergranular stress corrosion cracking(IGSCC) resistance in a cold-rolled and subsequently annealed Fe-18 Cr-17 Mn-2 Mo-0.85 N high-nitrogen nickel-free austenitic stainless steel were systematically *** results show that stacking faults and planar slip bands appearing at the right amount of deformation(lower than 10%) are beneficial cold-rolled microstructures to the GBCD *** proportion of special boundaries gradually increases in the subsequent stages of recrystallization and grain growth,accompanying with the growth of twin-related domain in the experimental *** this way,the fraction of low ∑ coincidence site lattice(CSl) boundaries can reach as high as 82.85% for the specimen cold-rolled by 5% and then annealed at 1423 K for 72 *** GBCD optimization,low ∑ CSl boundaries and the special triple junctions(J2,J3) of high proportion can greatly hinder the nitride precipitation along grain boundaries and enhance the capability for intergranular crack arrest,thus improving the IGSCC resistance of the experimental steel.

1 Results Palygorskite (PGS) is a chain-layer magnesium-aluminum silicate mineral. Because of its developed interior channels and large specific surface area, and thus considerable adsorption capacity, it has been studied for the application as one of environmental mineral adsorbents[1-3]. Cyclodextrins (CD) possess a hydrophilic exterior and a hydrophobic interior into which a variety of hydrophobic organic molecules maybe introduced.

The microstructuralchangeof mechanicalalloyingof pureelemental Mg Nipowders wasin vestigated by transmission electronic microscopy ( TEM). The experimental results showed thatafter5 h milling, Mg2 Ni phase precipitated mainly from Mg grain , and no Mg2 Ni wasfound in Ni matrix. Thiscan be attributed tothe asym metricalinterdiffusion between Mg and Ni atom , which causesthecontent of Mg in Ni grain far below thestoichiometric composition of Mg2 Ni. After the growth of Mg2 Ni grain, the severe mechanical deforma tion resulting from mechanicalalloying led tothetransformation of Mg2 Ni from hexagonal tofccstructure partially, which makes Mg2 Ni grain in a composite microstructure fcc + hcp.
