Internal Friction in Fe-Co-Ni-Ti Shape Memory Alloys
The anomalies of the temperature dependences of the logarithmic decrement and eigen frequency of the free damped vibrations for Fe-Co-Ni-Ti shape memory alloys were first found in the vicinity of the reverse ay martensitic transformation. It was shown the damping capacity in the alloys investigated is comparable with that for TiNi based alloys.
متن کاملAN ATOM-PROBE STUDY OF Fe-Ti ALLOYS
The ToF atom-probe FIM was used to study surface segregation of Fe-Ti alloys. Ti segregates to the surface upon annealing at or above 650°C. The degree of segregation depends on the crystallographic orientation, 100% at the (110) and (111), 70% at the (100) and £50% at the (121) plane. It is found that the presence of H2(D2) during annealing enhances surface segregation of Ti and that oxygen de...
متن کاملCorrosion Characteristics of a - Ti and Ti 2 Cu Composing Ti - Cu Alloys
A series ef binary Ti-Cu alloys containing 5-20 mass% Cu was prepared, and the corresien behavior of a-Ti and Ti2Cu composing the Ti-Cu alloys were examined based on the anodic polarization curves and released iens in O.9% NaCl and 1% lactic acid solutions. In both selutions, the Ti-Cu alloys showed the same anodic polarization curves as titanium in the conditien below 1.4 V. Hewever, precipita...
متن کاملElectron-induced Ti-rich surface segregation on SrTiO3 nanoparticles.
Atomic surface structures of nanoparticles are of interest in catalysis and other fields. Aberration-corrected HREM facilitates direct imaging of the surfaces of nanoparticles. A remaining concern of surface imaging arises from beam damage. It is important to identify the intrinsic surface structures and the ones created by electron beam irradiation in TEM. In this study, we performed aberratio...
