Abstract

This data set contains high-resolution micrographs of the transverse sections of partially molten samples deformed in torsion. These micrographs present the distribution of melt induced by deformation, which is a test of the melt segregation processes predicted by the two-phase flow theory incorporating viscous anisotropy.

Description

An excel spreadsheet summarizes the experimental conditions of the samples included in this data set, and also includes figures that plot the azimuthally averaged, normalized melt fraction vs. the radius for the starting material and each experimental condition. For each sample (with the exception of experiment PT0767), the following data are included. 1. Tiles of 8-bit gray-scale optical microscopic images of 1000x1000 pixels. 1 pixel = 0.32 micron. There is ~20% overlapping between each tile. 2. A txt file registering the relative coordinates of each tile. 3. A black and white image with melt being white processed from the tiles and assembled by their coordinates. 1 pixel = 0.32 micron. 4. A mosaic microscopic image with lower resolution. In the file name, "OL" stands for optical light. 1 pixel = 1.3 micron. For experiment PT0767, no high resolution images were obtained for this sample. For experiment PT0817, two files with relative coordinates exist, with one overlapping row that can be used to stitch the two halves together.
