(PDF) Strain localization and damage in dual phase steels

SE imaging of etched surfaces allows large field-of-view imaging of statistically representative areas of the microstructure, however, provides relatively low strain resolution (due to the ferritic zones without significant contrast in the etched microstructure) and limited maximum strain level (due to deformation induced roughening).Prior to deformation, 0.05 lm step size electron backscatter diffraction (EBSD) measurements are carried out on the undeformed surface

CH31 vapor etching of masked and patterned GaAs

the etch rate of (100)A1GaAs epilayers was equal to that of GaAs [1]. This result is in contrast to HC1 vapor etching for which the etch rate de- creases with increasing AlAs mole fraction [3,4]. Thus, CH3I vapor etching is a promising in-situ process for OMVPE. Calcite dissolution rates in seawater:Lab vs. in-situ Sep 20, 2019 · In-situ saturation was calculated using both Alk-DIC ( (Alk, DIC)) and Alk-pH ( (Alk, pH)) pairs. We compare in-situ dissolution rates with rates measured in filtered, poisoned, UV-treated seawater at 5 and 21 °C under laboratory conditions. We observe in-situ dissolution above (Alk, DIC) = 1, but not above (Alk, pH) = 1.

Chlorine Etching For In-Situ Low-Temperature Silicon

Experiments were done to test the ability of chlorine surface etching steps to remove other surface impurities, specifically phosphorus. A thermal desorption step at 800oC, a chlorine surface cleaning step by etching at 575oC, and no in-situ cleaning were compared. Silicon was grown in this experiment at 700oC at 6 torr chamber pressure Combination of Different In Situ Characterization Jun 03, 2015 · The indentation tests were also performed on the polished surface. The specimen surface for the application of the DIC on SEM micrographs obtained from interrupted in situ tensile tests was finally etched with a V2A etching agent. The DIC was performed using the ARAMIS software package (GOM). A detailed description of the DIC parameters is

Controlled oxidative etching of gold nanorods in-situ

May 29, 2020 · ing [13], shape-dependent etching kinetics [14], and ki-netically driven nanocrystal morphology evolution [15,16]. However, there are limited systematic studies that can directly compare the kinetics and pathways of nanostructure etching under controlled etching condi-tions. Here, we use in-situ liquid cell transmission electron EXPLORING NOVEL GLASS MICROFABRICATION near the surface of the wafer through a diffuser gas inlet, etch rates as high as 1.06 m/min, 1.04 m/min, and 0.45 m/min with surface smoothness of ~2 Å, ~67 Å, ~4 Å are achieved for fused silica, borosilicate glass, and aluminosilicate glasses respectively after 5 minutes etches.

Effect of overlap distance on the microstructure and

Jan 25, 2019 · DIC in situ tracks the deformation of patterns placed on the surface of the specimens to determine the strain fields. For optical microscopy (OM) and scanning electron microscopy (SEM) observations, polished specimens were etched in a Kroll's Reagent (23% HF, 45% HNO 3, 9294% H 2 O). To be representative, all microstructures were taken from the midline area of each specimen. Formation dynamics of hexadecanethiol self-assembled self-assembled monolayer SAM on the GaAs 001 surface was studied in situ by monitoring the photoluminescence PL intensity over a 20 h period. Comparing the PLtime series in HDTsolution with that of the bare GaAs surface similarly exposed to the ethanol solvent, we observed a two-phased evolution of the associated PL enhancement.

Objective The main objective of this paper is to show evidence of the reliability of the field results using in situ metallography for representing the bulk microstructure of the metallic

In-situ analysis of an industrial material compound

in Sec. 4. Experimental in-situ measurements and the respective results are discussed in Sec. 5. 2 In-Situ Heating Equipment There are numerous requirements on the load test device, if one wants to stress a sample thermally inside the nanotom®. Firstly, there are Investigation of thin oxide layer removal from Si clean is removing the native oxide, leaving a clean Si surface with only small amounts of carbon and fluorine. Below we will compare silicon surfaces after various dry etching steps to the results after a dilute HF wet clean. 3.1.2. Ar sputtering. Plasma-based Ar sputtering is often per-formed in process chambers prior to metallization, and serves

Jan 08, 2020 · Differential Interference Contrast (DIC), also known as Nomarski Contrast, helps to visualize small height differences on the specimen surface, thus enhancing feature contrast.DIC uses a Wollaston prism together with a polarizer and analyzer whose transmission axes are perpendicular (crossed at 90°) to each other. The two light waves split by the prism are made to interfere after Modification for prediction model of austenite grain size Jan 05, 2021 · The results indicate that full austenite grains were formed above 1350 °C and the exit temperature of the casting mold was approximately 1300 °C. Thus, T C was set at 1350 °C to simulate the behavior of the austenite grain growth in the casting mold. After the experiment, the sample was polished and its surface was etched using 4 vol.% Nital.

Passivation mechanisms in cryogenic SF6/O2 etching process

Feb 01, 2004 · Surface analysis by quasi in situ x-ray photoelectron spectroscopy (XPS) experiments was performed on Si wafers in a pure SF 6 low temperature etching process by Tessier et al . However, to our knowledge, in the SF 6 /O 2 mixture cryogenic etching process, nothing was published about the composition of the passivating layer, which is usually Probing the Roles of Polymeric Separators in Lithium-Ion May 30, 2014 · In this paper, the temperature dependent micro-scale morphology change of PP (polypropylene)-PE (polyethylene)-PP sandwiched separators (Celgard 2325) was studied by in-situ high temperature surface imaging using an atomic force microscope (AFM) coupled with power spectral density (PSD) analysis and digital image correlation (DIC) technique.

Real-Time Reactive Ion Etch Metrology Techniques to

Model results and verification using these in situtechniques indicate no loss of accuracy when compared with traditional ex situ measurement methods for response surface design. Though the ISDOE concept is demonstrated here specifically on etch rate data, the general idea can be applied to many other real-time wafer state measurement methods. Reduction of structural defects in thick 4H-SiC epitaxial 2 ratio, and in situ pre-growth surface etching time are studied. It was found that an in-situ pre growth etch at growth temperature and pressure using 0.6% HCl in hydrogen for 12min reduced the structural defects by etching preferentially on surface damages of the substrate surface. By then applying a slightly lower growth temperature of 1575 C,

14 of the lamp and alignment of illumination with the sample surface, a UPS spectrum was 15 collected from an Ag foil sample etched with a Gas Cluster Ion Source (Minibeam for at 16 least 60s. During in situ irradiation of the WO3, 2 and WO3-TiO2 samples, 17 only high-resolution spectra collected. Data collection near the Fermi edge using the Tin Oxide Dependence of the CO Reduction Efficiency on Strikingly, an etched Sn electrode exhibited a much higher j tot of 34mA/cm2 but very low faradaic efficiencies for production of CO (0.5%) and HCO 2 H (0.3%) (Figure 1c). The higher j tot likely reflects a larger electrochemical surface area due to etching. Despite the higher surface area, the geometric partial current density for CO 2
