This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Secondary ion mass spectrometry (SIMS) and orientation imaging microscopy (OIM) were used to study the relationship between boron segregation susceptibility at grain boundaries and grain boundary structure in Alloy 304 austenitic stainless steel containing boron as a trace solute impurity. Boron segregation was detected at grain boundaries in materials heat treated at 1000 and 1100°C and both boron segregation and carbide precipitation were detected at grain boundaries in materials heat treated at 800°C. Coherent 3 twin boundaries displayed high resistance to both boron segregation and carbide precipitation. 1 (low-angle) boundaries displayed some resistance to boron segregation and high resistance to carbide precipitation. 9 boundaries satisfying the Palumbo-Aust criterion displayed some resistance to both boron segregation and carbide precipitation. Other low- boundaries and general boundaries ( > 29) displayed low resistance to both boron segregation and carbide precipitation.

Available in PDF, EPUB and Kindle. Book excerpt: Grain boundaries are important structural components of polycrystalline materials used in the vast majority of technical applications. Because grain boundaries form a continuous network throughout such materials, their properties may limit their practical use. One of the serious phenomena which evoke these limitations is the grain boundary segregation of impurities. It results in the loss of grain boundary cohesion and consequently, in brittle fracture of the materials. The current book deals with fundamentals of grain boundary segregation in metallic materials and its relationship to the grain boundary structure, classification and other materials properties.

This book was released on 1998-11-25 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continuing the scope of the preceding Conferences on Intergranular and Interphase Boundaries in Materials, the present conference focused on the atomic-level modeling of interfaces, the structural and chemical characterization of internal interfaces, on their thermodynamic, kinetic, mechanical, electrical, magnetic behavior and high-Tc superconductivity, and on the application of current knowledge to the design of polycrystalline materials having improved properties. Particular attention was paid to non-equilibrium segregation in irradiated materials. Volume is indexed by Thomson Reuters CPCI-S (WoS).

Download or read book Boron Segregation to Grain Boundaries and Improved Ductility in Pt 30 Wt Rh 8 Wt W written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Boron additions of up to 75 wt ppM have been observed to improve the room temperature strength and ductility of a Pt + 30 wt % Rh + 8 wt % W alloy. Alloys without boron fail intergranularly, and those with 75 wt ppM boron added fail in a mixed intergranular-transgranular mode. Auger electron spectroscopy on intergranular fracture surfaces indicated that boron segregates strongly to grain boundaries in the boron doped alloys. Transmission electron microscopy of alloys with and without boron indicated that both were free of internal precipitates. The observed improvements in strength and ductility appear to be related to boron enrichment within a few atomic distances of the grain boundary.

Book excerpt: Trace elements and impurities often segregate strongly to grain boundaries in metals and alloys. Concentrations of these elements at grain boundaries are often 103 to 105 times as great as their overall concentration in the alloy. Because of such segregation, certain trace elements can exert a disproportionate influence on material properties. One frequently observed consequence of trace element segregation to grain boundaries is the occurrence of grain boundary failure and low ductility. Less well known are incidences of improved ductility and inhibition of grain boundary fracture resulting from trace element segregation to grain boundaries in certain systems. An overview of trace element segregation and intergranular failure in a variety of alloy systems as well as preliminary results from studies on Al 3% Li will be presented.
