X‐Ray Computed Tomography Quantifies Primary Phases and Reveals Crack Morphology in High‐Cycle Fatigue of Aluminum Alloy EN AW‐2618A

open access: yesAdvanced Engineering Materials, EarlyView.
Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Glass modified barium strontium titanate ceramics for energy storage capacitor at elevated temperatures

open access: yesJournal of Materiomics, 2019
A glass with composition of B2O3-Bi2O3-SiO2-CaO-BaO-Al2O3-ZrO2 (BBSZ) modified BaxSr1-xTiO3 (BST, x = 0.3 and 0.4) ceramics were prepared by a conventional solid state reaction method abided by a formula of BST + y%BBSZ (y = 0, 2, 4, 7, and 10, in mass).

Seriation Proposed by Kleinschmidt (1982: Table 19) of Allen Phase and Frankston Phase Sites in the Upper Neches River [PDF]

open access: yes, 2007
Kleinschmidt reviewed sherd and vessel collections from a number of Frankston phase (ca. A.D. 1400-1650) and Allen phase (ca. A.D. 1650-1800+) sites in the upper Neches River basin (Anderson, Cherokee, Henderson, and Smith counties) and developed a ...

Tribology of ZrC Coatings and Spherical Tips Acquired with Extraordinarily Stiff, Metal Atomic Force Microscopy Probes

open access: yesAdvanced Engineering Materials, EarlyView.
In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...
