The effect of grain size and initial texture on ...

2019-09-01  The present study investigated the influence of grain size and initial texture on the microstructure, texture, and formability of a niobium-stabilized ferritic stainless steel processed by two-step cold rolling. The characterization of the samples was performed by X-ray diffraction, electron backscatter diffraction, and tensile tests in order to evaluate the formability by the average normal ...

2017-07-13  EBSD-based analysis was done on these samples in order to get more information regarding the grain size, texture, etc. Figure 2 a, b shows the IPF maps of Ti-20 wt% V and Ti-12 wt% Mo, respectively. From this, it can be seen that the grains are very columnar in growth and are usually more than 2 mm in size along the long axis.

Sand Grain Size Analysis - Faculty

During the lab you will measure grain size in two different ways: a) using a settling tube and b) using sieves. Texture refers to properties of a sediment such as particle size, shape, roundness, and sorting. A well sorted sediment is one in which the grains are all about the same size. In contrast, a poorly sorted sediment contains a chaotic mixture and large, intermediate and small grains ...

1999-01-01  These terms can be used in Folk's texture classification to derive detailed descriptions such as "angular, poorly sorted, fine to coarse boulder conglomerate". This grain-size scheme is further extended to account for particles coarser than boulders (d I >4.1 m), which we collectively call mega-clasts, and the sediment they comprise megagravel or, if lithified, megaconglomerate.

Grain size - Wikipedia

Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals. Granular material can range from very small ...
