The amorphous phases of the Pd-Cu-P system has been obtained using the technique of rapidly quenching from the liquid state. Broad maxima in the diffraction pattern were obtained in the X-ray diffraction studies which are indicative of a glass-like structure. The composition range over which the amorphous solid phase is retained for the Pd-Cu-P system is (Pd100[subscript x]Cu[subscript x])0P20 with 10 d"x d"50 and (Pd65Cu35)100−[subscript y]P[subscript y] with 15 d"y d"24 and (Pd60Cu40)100−[subscript y]P[subscript y] with 15 d"y d"24. The electrical resistivity for the Pd-Cu-P alloys decreases with temperature as T2 at low temperatures and as T at high temperatures up to the crystallization temperature. The structural scattering model of the resistivity proposed by Sinha and the spin-fluctuation resistivity model proposed by Hasegawa are re-examined in the light of the similarity of this result to the Pt-Ni-P and Pd-Ni-P systems. Objections are raised to these interpretations of the resistivity results and an alternate model is proposed consistent with the new results on Pd-Cu-P and the observation of similar effects in crystalline transition metal alloys. The observed negative temperature coefficients of resistivity in these amorphous alloys are thus interpreted as being due to the modification of the density of states with temperature through the electron-phonon interaction. The weak Pauli paramagnetism of the Pd-Cu-P, Pt-Ni-P and Pd-Ni-P alloys is interpreted as being modifications of the transition d-states as a result of the formation of strong transition metal-metalloid bonds rather than a large transfer of electrons from the glass former atoms (P in this case) to the d-band of the transition metal in a rigid band picture.

The papers making up this volume represent a summary of the proceedings of the Second International Symposium on Amorphous Magnetism held at Rensselaer Polytechnic Institute on August 25- 27, 1976. As a result of the resounding success of the Inter national Symposium on Amorphous Magnetism held at Wayne State University on August 17 and 18, 1972 this symposium was again organized with the purpose in mind of providing a forum for dis cussion of the most recent theoretical and experimental advances made in the fields of spin glass systems, amorphous magnetic alloys and magnetic oxide glasses. The symposium was sponsored by the American Physical Society and supported by a grant from GTE Laboratories. Additional support funds were provided by General Electric, Allied Chemical and Ford Motor Company. The program committee consisted of J. J. Becker (General Electric), P. A. Casabella (RPI), P. J. Cote (Watervliet Arsenal), A. M. de Graaf (Wayne State University), R. Hasegawa, Co-Chairman (Allied Chemical), H. O. Hooper (University of Maine), H. B. Huntington (RPI), R. A. Levy, Chairman (RPI), R. K. MacCrone (RPI), L. N. Mulay (Penn State University), G. L. Salinger (RPI) and J. Wong (General Electric). The program of the symposium included 7 invited review papers, 53 contributed papers, and 10 additional papers read by title because of time limitations. The editors wish to extend their deep appreciation to J. J. Becker, A. M. de Graaf, P. Duwez, J. Gustafson, D. L. Huber, U.

In spite of the large amount of research activity in this subfield of materials science and engineering, there is no single book available that provides background information, methods of synthesis, characterization procedures, properties, and potential and existing applications.of bulk metallic glasses. Written in an easy-to-understand style by pioneering researchers in this field, Bulk Metallic Glasses is one of the first books to coherently discuss the synthesis, processing, properties, and applications of these unique materials. The book explores the differences between nanocrystalline, glassy, and amorphous solids as well as the thermodynamics and kinetics and various processing methods of glass formation. It critically compares the different criteria for glass formation, describes the advantages and limitations of experimental methods for synthesizing bulk metallic glasses in assorted sizes and shapes, and examines the kinetics of crystallization/devitrification and the mechanisms of transformations. It also covers the density, diffusivity, thermal expansion, electrical resistivity, specific heat, viscosity, corrosion resistance, mechanical behavior, and magnetic properties of bulk metallic glasses. After presenting a wide array of applications, the book concludes with a discussion on the future of these materials. The adoption of bulk metallic glasses into existing systems is besieged by many obstacles but due to their interesting combination of properties, future applications may be unlimited. A one-stop resource on all aspects of bulk metallic glasses, this book demonstrates the immense potential of these novel materials. It clearly elucidates the background, detailed methods of synthesis and characterization, structure, and properties of bulk metallic glasses.
