Conductive polymer compositions and articles containing same

Abstract: Polymer compositions, which are particularly useful in automotive applications, are described. The polymer composition contain at least one polymer and at least one carbon black having an STSA (statistical thickness surface area) of from about 10 to about 200 m2/g, an I?2?No of from about 15 to about 250 mg/g, a tinting strength about 130% or less, a DBPA of from about 20 to about 450 cc/100g, a CDBP of from about 20 to about 400 cc/100g, a ratio of I2No to STSA of from about 0.4 to about 2.5, a particle size of from about 14 to about 250 nm, and a %volatiles of less than about 5.0%. Articles for automotive applications and other applications, as well as a method for electrostatically painting an article are also disclosed.

A method of forming sputtering target assembly and assemblies made therefrom

Abstract: A method of forming a sputtering target assembly is described that involves explosively bonding a target grade plate and a backing plate member to form a bonded preform having dimensions such that a large target or several target assemblies can be obtained. The method includes partitioning the bonded preform into a plurality of sputtering target assemblies. An interlayer can optionally be disposed between the target grade plate and the backing plate member before bonding. A bond quality test sample can be produced by the method. The sputtering target assemblies, the bonded preform, and the bond quality test sample are further described.

Experimental observations of transient phases during long‐range ordering to Ni4Mo in a NiMoFeCr alloy

Abstract: Experimental observations are reported of transient phases which form during long-range ordering to Ni4Mo (f.c.c. Dla superlattice) in the quaternary alloy Ni–19.2 at% Mo–1.2 at% Fe–1.06 at% Cr using electron diffraction. In the early stages of ordering during isothermal annealing, diffuse intensity maxima centered at the short-range order reflections {1 1/2 0}f.c.c. and along 〈100〉f.c.c. directions are observed. Subsequently, a DO22 superlattice is generated from the short-range order state. The coexistence of the DO22, Pt2Mo-type, and Dla superlattices is observed in this alloy system which indicates that these three superlattices have similar energy. With continued annealing, both the DO22 and Pt2Mo-type superlattices disappear, indicating that they are transient phases. These results are not inconsistent with the theoretical treatments of ordered alloys which are based on an Ising model with pairwise atomic interactions. Es werden mittels Elektronenbeugung die nichtstationaren Phasen experimentell untersucht, die sich wahrend des Prozesses der Fernordnung zu Ni4Mo (k.f.z. Dla-Supergitter) in der quaternaren Legierung Ni–19,2 At% Mo–1,2 At% Fe–1,06 At% Cr bilden. In den fruhen Zustanden der Ordnung wahrend des isothermen Temperns, werden diffuse Intensitatsmaxima beobachtet, die den Nahordnungsreflexionen {1 1/2 0}k.f.z. und in 〈100〉k.f.z.-Richtungen zentriert sind. Darauffolgend wird ein DO22-Supergitter aus dem Nahordnungszustand gebildet. Die Koexistenz der DO22-, Pt2Mo- und Dla-Ubergitter wird in diesem Legierungssystem beobachtet, was zeigt, das diese drei Ubergitter ahnliche Energie besitzen. Bei fortgesetzter Temperung, verschwinden sowohl das DO22-als auch das Pt2Mo-Supergitter. Das zeigt, das sie nichtstationare Phasen sind. Diese Ergebnisse sind nicht inkonsistent mit den theoretischen Behandlungen von geordneten Legierungen, die auf dem Ising-Modell mit paarweiser atomarer Wechselwirkung beruhen.

Apparatus for densifying powders of sub-micron particle size

Abstract: There is disclosed herein powder densifying apparatus comprising a pair of opposed gas-permeable belts arranged to either side of a common axis so as to define a generally convergent densifying zone between their adjacent faces. The belts are multiply supported spanwise by a plurality of opposed spaced apart support rolls, each opposed pair of rolls defining a densifying station therebetween. The gas-permeable belts are driven toward the convergent end of the densifying zone at substantially equal speeds while powder material to be densified is fed into the divergent end of the densifying zone at a rate sufficient to maintain a substantially complete fill thereof.
