“…Indeed, material was not lost during the welding process. In an attempt to validate the cross‐sectional area measurements, analysis was performed on a three‐dimensional image that was constructed from two‐dimensional slices that were collected using an automated serial sectioning process . Phase volumes were determined by summing the area fractions of specific phases for each slice of the reconstructed three‐dimensional image.…”

A silicon carbide‐based ceramic, containing 50 vol% SiC, 35 vol% ZrB2, and 15 vol% ZrC was plasma arc welded to produce continuous fusion joints with varying penetration depth. The parent material was preheated to 1450°C and arc welding was successfully implemented for joining of the parent material. A current of 138 A, plasma flow rate of ~1 L/min or ~0.5 L/min, and welding speed of ~8 cm/min were utilized for repeated joining, with full penetration fusion zones along the entire length of the joints. Solidification was determined to occur through the crystallization of β‐SiC (3C), then the simultaneous solidification of SiC and ZrB2, and lastly through the simultaneous solidification of SiC, ZrB2, and ZrC through a ternary eutectic reaction. The ternary eutectic composition was determined to be 35.3 ± 2.2 vol% SiC, 39.3 ± 3.8 vol% ZrB2, and 25.4 ± 3.0 vol% ZrC. A dual fusion zone microstructure was always observed due to convective melt pool mixing. The SiC content at the edge of the fusion zone was 57 vol%, while SiC content at the center of the fusion zone was 42 vol% although the overall SiC content was still nominally 50 vol% throughout the entire fusion zone.

“…Although serial sectioning, x-ray tomography, atom probe tomography, and other data collection techniques have been employed for some years, 1-8 new collection methods are being introduced that are either partially or fully automated. 9,10 Automated data collection techniques, particularly those that can incorporate crystallographic measurements, remove the initial barrier to 3D materials analysis-the perception that unsupportable investments of time and resources are required for data collection. (Although data collection certainly requires significant investment of time and resources, many have noted that far more time and resources are expended on the processing and analysis of the data.…”

“…Although extremely time consuming this method has the advantage over tomography techniques (see next paragraph) of being able to picture particles in a medium showing a poor contrast. It can also be associated to a series of microanalytical instruments to offer 3D imaging coupled to EDX and EBSD information for example (Uchic et al, 2011).…”

In recent years, impressive progress has been made in digital imaging and in particular in three dimensional visualisation and analysis of objects. This paper reviews the most recent literature on three dimensional imaging with a special attention to particulate systems analysis. After an introduction recalling some important concepts in spatial sampling and digital imaging, the paper reviews a series of techniques with a clear distinction between the surfometric and volumetric principles. The literature review is as broad as possible covering materials science as well as biology while keeping an eye on emerging technologies in optics and physics. The paper should be of interest to any scientist trying to picture particles in 3D with the best possible resolution for accurate size and shape estimation. Though several techniques are adequate for nanoscopic and microscopic particles, no special size limit has been considered while compiling the review.
