Microstructure and 3-d Effects in Fretting Fatigue of Ti Alloys and Ni-base Superalloys
Damage and plastic deformation accumulation in fretting fatigue occurs within a depth of a few crystallographic grains. Therefore, more accurate assumptions concerning length scale, damage volume, and the material model are needed to establish a more solid physical foundation necessary for next generation fretting fatigue damage prediction. Major thrusts include: (1) development and implementat...
متن کاملFactors affecting the nitridation behavior of Fe-base, Ni-base, and Co-base alloys in pure nitrogen
The behavior of alloys in nitrogen at high temperature is relevant to many industrial applications. Embrittlement due to internal nitride formation is the principal problem encountered in service. In this study, the nitridation resistance of a series of alloys in pure nitrogen at 1093 O C was investigated. For Fe-base, Ni-base, and Co-base alloys the amount of nitrogen absorbed and the nature a...

متن کاملDesign and development of novel antibacterial Ti-Ni-Cu shape memory alloys for biomedical application
In the case of medical implants, foreign materials are preferential sites for bacterial adhesion and microbial contamination, which can lead to the development of prosthetic infections. Commercially biomedical TiNi shape memory alloys are the most commonly used materials for permanent implants in contact with bone and dental, and the prevention of infections of TiNi biomedical shape memory allo...
متن کاملEvaluation of a Rayleigh-Number-Based Freckle Criterion forPb-Sn Alloys and Ni-Base Superalloys
A criterion for predicting the formation of freckles for Pb-Sn and Ni-base superalloys is evaluated using available experimental data. The criterion is based on a maximum value of the Rayleigh number, which indicates that the magnitude of buoyancy forces is largest with respect to the retarding frictional forces. The definition of the Rayleigh number involves a characteristic length scale. The ...
