Vanadium Carbides

Spheroidal carbides cast irons (SCIs) are used in severe conditions where often occur erosion and due to their excellent wear resistance characteristics. In this study, three kinds of SCIs with a variation in matrices are tested and evaluated as shredding blade of uniaxial rotary glass shredder in recycling factories where often occurs extreme abrasion with the crushed glass. They are SCI-VCrNi, SCI-VMn, and SCI-Vw with hard (2400Hv) spheroidal vanadium carbides (VC). As a result, SCI-Vw reveals excellent wear resistance, approximately 1/12 of wear removal in weight, compare to other two materials of SCI-VCrNi and SCI-VMn. Spheroidal carbides nodularity(70%) and volume fraction of VCs(approximately 20%) are similar in three kinds of SCIs. The hardness of matrix of SCI-Vw (800Hv) is greater than that of SCI-VCrNi (320Hv) and SCI-VMn (380Hv). Therefore the experimental results are interpreted that hardness of matrix are dominant factor for abrasion. Based on this experimental study, SCI-Vw is an effective material for abrasion occurred on the blade of the glass shredder.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
