Length Scale and Aging Effect on the Mechanical Properties of a 63Sn-37Pb Solder Alloy

Description: In this work, uniaxial tensile testing of a 63Sn-37Pb alloy with different specimen sizes and aging conditions had been carried out. Although the stress-strain responses of different specimen sizes and aging conditions differs, the ultimate strength of the specimens with 16 hours, 100 C aging are similar for the sizes tested. The specimens with 25 days, 100 C aging have different stress-strain response with different sizes, and have a lower ultimate strength and higher failure strain compared t… more

A PIV Methodology for High-Resolution Measurement of Flow Statistics

Description: Particle-image velocimetry (PIV) is a flow-diagnostic technique that provides velocity fields from a comparison of images of particulate-laden flow. We have developed a PIV processing methodology that extracts measurements of the particle-displacement histogram from a flow video or ensemble of flow-image pairs. Single-pixel measurement of mean velocity can be obtained from an ensemble of {Omicron}10{sup 3} images. Measurements of higher-order moments of the velocity histogram require spatial av… more
