hardness. Thus, different diamond grinding wheels are used as cutting tool. Grinding condition which results in higher grinding forces, generates higher heat and stress in the contact zone, which leads......
are in line with the demand for LMD. Impurity elements in titanium have a substantial influence on the comprehensive properties of titanium, especially C, N and O. Oxygen can improve the strength and hardness......
at the midpoint, which decreases in both longitudinal and transverse paths starting from the midpoint. The Vickers micro- hardness was measured at 5 points (with equal intervals of 10 mm) in the longitudinal......
): 894-899. DOI: https://link.springer.com/article/10.1007/ s11665-009-9559-7. [41] TLOTLENG M, AKINLABI E, SHUKLA M, PITYANA S. Microstructures, hardness and bioactivity of hydroxyapatite coatings......
] discovered through a hardness test that HE occurred in mild steel with yield strength of 400 MPa. Similarly, EGGUM [23] discovered degraded mechanical properties for samples with yield strength......
surface tension because the agglomerated particles were not observed. With long milling time, the powder particles get work-hardened, which increases their hardness and brittleness; whereas the particle......
[14], Al3NiTi2 and TiNiAl intermetallics exhibit the similar structures and the hardness of AlNiTi is about 17.2 GPa, which is higher than that of AlNi2Ti, TiNi3, TiAl and Ti3Al intermetallics as well......
and porous in rock material, such as the existence of micro-cracks, micro-cavities and minerals of differing hardness. When rock samples are loaded, the material heterogeneity leads to the propagation......
, 8]. The BQ involves two basic factors and three corrected factors. The basic factors include rock integrity coefficient and rock hardness coefficient, which reflects the effects of discontinuities......
was carried out. The results showed that the sol-gel samples had improved setting time, higher hardness value and better antimicrobial activity [19]. SORRENTINO [20] reported the preparation of the pure C3S......
