A microtexture based analysis of surface roughening in ductile metals during tensile deformation
… diffraction techniques were used to measure the microtexture, and analysis of this data allowed the calculation of the plastic flow behaviour of discrete volumes of the sample material. The yield behaviour was implemented in a finite element model to simulate the material behaviour under uniaxial …

Engineered surfaces for enhanced control of electrochemical bubbles
… are able to demonstrate that there is an optimal microtexture that maximizes the electrochemical output for a given condition. As a result, this thesis presents a novel approach to rationally design the surfaces of electrochemical electrodes to move towards 'bubble-free' surfaces for a variety of …

Evaluating the Sensitivity of the Auckland Pavement Polishing Device and Analysis of Aggregate Microtextural Wear
… analysis of height, shape and volume microtexture parameters, using a 3D micro coordinate measurement device. Quantifies the evolution of microtextural wear during the polishing process by undertaking microtextural analysis, using a 3D micro coordinate measurement device. The …

Effect of hot working characteristics on the texture development in AISI 430 and 433 ferritic stainless steel
… in multi-pass tests. Both macrotexture (XRD) and microtexture (EBSD) analyses were employed to characterise and study the texture present in these steels. It was found that the texture in the central layer of the compressed sample is a strong recrystallization-type. The through-thickness textural …

Intense Shallow Magma Sediment Mingling within Dikes at Guffey Butte Maar, Idaho
… Through a combination of field mapping, microtexture measurements from 36 thin sections, and geochemistry (whole rock major and trace elements using XRF and ICP-MS), the scales of interactions and diversity of mixing styles between the basaltic dikes and host sediments were constrained. …

Time-Space-Resolved Raman Analysis of Structure-Property Relationships in Heterogeneous Structural Materials
… Furthermore, the mechanical contributions of the microtexture in drumfish teeth were studied through a correlative chemo-mechanical characterization. Next, the time component is added to the framework. Using the time-space-resolved Raman analysis framework, the molecular structure of C-S-H is …

Circumferential Three-Dimensional Profiling with Specular Micro-Texture Photometry for Dark Objects
… diffuse components, making the usage of general microtexture photometry more difficult. On the other hand, without using micro-texture photometry, the conventional circumferential 3D approaches only utilizes the geometric property of the target surface, compared to which, the proposed is able to …

Photometric stereo for micro-scale shape reconstruction
… designed for on-site measurement of pavement microtexture, while its applicability can be generalized to a wider range of surfaces. Optimal illumination was investigated in theory and through numerical simulations. Five different calibrations regarding various aspects of the system were either …

Reducing Highway Crashes with Network-Level Continuous Friction Measurements
… as skid resistance and is provided by pavement microtexture and macrotexture. The amount of skid resistance depreciates over time due to the polishing action of traffic, and for this reason, the skid resistance should be monitored with friction testing equipment. The equipment use one of four …

Precision rotational rheometry
… on torque measurement and (ii) effects of microtextured surfaces on shear stress under gap controlled conditions. Surface tension results in a torque that should not occur in an ideal, rotationally-symmetric geometry. This work identifies and explains the effect, which is due to surface …

Mikrotextur und magnetische Mikrostruktur in Hartmagneten aus (Nd,Pr)2Fe14B-Verbindungen
In der vorliegenden Arbeit werden die Zusammenhänge zwischen der magnetischen Mikrostruktur und der Ausrichtung der Kristallite, sowohl in Sintermagneten als auch in feinkristallinen, warmumgeformten Magneten auf Nd2Fe14B- und Pr2Fe14B-Basis, untersucht. Die EBSD-Technik (electron backscatter …

Solid-liquid interactions in microscale structures and devices
… wetting. The contact area between droplet and microtextured surface is then measured for a droplet in the Cassie state, which is a state of partial wetting. The results show that although the droplet is in the Cassie state, the contact area does not necessarily follow Cassie model predictions. …
