The objective of the current study is to determine the fatigue limit of a clean and high-performance material named as HSLA-100 steel and to compare the obtained fatigue limit with that of theoretically predicted fatigue limit by statistics of extreme value (SEV) method. Also, the size of inclusions located at the site of fatigue crack nucleation on the fracture surface of the fatigue test spec...
The osseointegration of oral implants is related to the early interactions between osteoblastic cells and titanium surface. Chemical surface modification of titanium (Ti) implants is used to improve peri-implant bone growth, bone-to-implant contact, and adhesion strength. Thus, in this study, the surface topography, chemistry, and biocompatibility of polished titanium surface treated with mixe...
In this paper, the effect of TiH2 and CaCO3 blowing agents was investigated on the structure and energy absorption of Al-7%Si-3%SiC composite metal foam by powder compact route. Composition of the foam was prepared from a mixture of Al, SiC and Si powders. Then, precursors were consolidated in H13 die mould by cold and uni-axial pressing at 110 MPa and at room temperature. The pressed precursor...
