... was proposed based on microstructure, microhardness, and residual stresses of CD stud welded joint. The results show that a narrow weld seam with a widmanstaten structure is formed because of quick cooling. For the longer stud extension length, the width of the weld zone becomes wider and the microstructure...

... tests carried out on specimens cut from different positions in the tubes parallel to their axes. The distributions of the Vickers hardness over the surfaces at 0 deg and 90 deg to the drawing direction were examined. It was found that the microhardness, yield strength, and ultimate tensile...

...J. Xie The natural granite includes various hard and brittle minerals with different material behaviors. In this paper, the discrete distribution parameters of microhardness and microbrittleness are proposed to describe its micron-scale material behavior. The objective is to evaluate and predict...

.... The experiments provide the evidence that the addition of Si 3 N 4 can improve the densification kinetics of 420 SS significantly. The 420 SS samples produced by 3DP with 12.5 wt % Si 3 N 4 sintered at 1225 ° C for 6 h yielded 95% relative density, 190 GPa Young’s modulus, and 500 Knoop microhardness without any...
