Electrical Resistivity of SmAg, SmCu, and SmAu

The electrical resistivity of equiatomic phases of Sm with Cu, Ag and Au was measured down to 4.2°K. Anomalies were found at 10°K for SmCu and at 42°K for SmAg. The resistivity-temperature curve of SmAu has a maximum at 40°K and a minimum at 53.5°K

CsCl-type compounds in binary alloys of rare-earth metals with gold and silver

In binary alloys of silver with Sm, Tb, Ho, and Tm, and of gold with Y, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, and Tm, intermediate phases containing stoichiometric proportions of the two metals were found to crystallize into the CsCl (B2)-type structure. The lattice parameters of these phases are reported and a correlation has been found between these lattice parameters and the trivalent ionic radii of the rare-earth metals

NMR Knight shifts and linewidths in the Ni‐Pd‐P and Ni‐Pt‐P metallic glasses: Composition and temperature dependences

NMR Knight shift and linewidth measurements are reported for the ^(31)P nuclei in the metallic glasses (Ni_(0.50)Pd_(0.50))100−_xP_x (where x=16 to 26.5) and (Ni_yPd_(1−y))_(80)P_(20) (where y=0.20 to 0.80), and both the ^(31)P and 195Pt nuclei in the metallic glass (Ni_yPt_(1−y))_(75)P_(25) (where y=0.20 to 0.68). The results are discussed in terms of the amorphous structure, electronic structure, and stability of transition metal + metalloid metallic glasses

Interview with Pol Duwez

An interview in seven sessions, April 1979, with Pol Duwez, professor emeritus of applied physics in the Division of Engineering and Applied Science. Recollections of his childhood in Mons, Belgium, during the German occupation in World War I. Educated at the School of Mines in Mons and the University of Brussels, where Auguste Piccard was one of his professors. Comes to Caltech in 1933 as a research fellow, working with Theodore von Kármán and Fritz Zwicky on the plasticity of metallic crystals. Comments on interest of R. A. Millikan and Piccard on cosmic rays. Returns to Belgium, 1935, to become director of its National Laboratory for Silicates; efforts to improve quality of Belgian ceramics. Birth of his daughter; he and his family escape wartime Europe, 1940. Back to Caltech; experiments on high-speed deformation of solids for National Defense Research Council. Discusses war work, German V-2 rocket, GALCIT’s rocket research, beginnings of JPL, director Frank Malina. To England in 1945 to investigate materials for use in rocket propulsion. Discusses his work on various postwar advisory boards; his interest in “new” metals (titanium, molybdenum) and their alloys and properties. Recalls Air Force summer study groups on Cape Cod and changes in wake of Sputnik. His X-ray diffraction laboratory. Work on rare-earth oxides. Comments on Von Kármán. Explains the evolution of the applied-physics option at Caltech. He describes the technique of “quenching” from the liquid state; extreme cooling with new alloys leads to new field of metallic glasses. Magnetism and superconductivity. Recalls attempts to make nuclear-powered airplanes and ramjets. He concludes with remarks on his style of teaching, the evolution of materials science, and the responsibilities and rewards of consulting for government, the armed services, and corporations

New CsCl-Type Intermediate Phases in Binary Alloys Involving Rare-Earth Elements

To further work on intermediate phases having the CsCl-type structure in binary alloys involving one rare earth, fifteen additional phases in alloys of rare earths with Zn, Cd, Hg, In, and Tl are described in this paper
