... by the nugget width and penetration. The nugget width may be different from the weld diameter, depending on the weld quality and testing method. The HAZ can be divided into two parts: a zone of solid-phase transformation near the base metal, and a partial-melting zone. It is beneficial to separate the partial...

... it depends on the cone angle. It is observed that the yield pressure increases as the cone semi-angle decreases, and the effect may be partially explained as due to friction between the indenter and the indentation ( Ref 15 ). The diamond pyramidal indenter was first introduced by Smith and Sandland...

Experience has shown that the distance from the center of the indentation to the edge of the workpiece must be at least 2 1 2 times the diameter of the indentation to ensure an accurate test. Therefore, the width of a narrow test area must be at least five indentation diameters when...

In addition, measurement of the notch depth at fracture allows the use of the same well-established equations...

... strengths for the two materials were about the same for a given d o . For values of d o greater than 40 mm (about 30% of the specimen width), the free edges probably exaggerated the strength reductions. That is, very wide specimens would have been stronger for the same d o . Fig. 8 Postimpact...

This is expected since this material exhibits no rate sensitivity in both its hardness ( Fig. 6 ) and constitutive response ( Fig. 7 ). The minor scatter seen in the microhardness contours may be a result of the natural scatter...
