Combined Effects of TiB Volume Fraction and Orientation on Four-Point Bending Fatigue Properties of TiB-Reinforced Ti–3Al–2.5V Composite
نویسندگان
چکیده
TiB-reinforced Ti–3Al–2.5V, in which the TiB whiskers are oriented parallel to direction of heat extrusion, was fabricated via powder metallurgy. To investigate effects whisker volume fraction on fatigue properties four-point bending tests were conducted plate-type specimens having varying and orientation. The limit life Ti–3Al–2.5V that loading tended be increase with increasing fraction, whereas along short transverse did not depend fraction. long decrease because cracks initiated propagated whiskers. Thus, resistances crack initiation propagation behavior changed both

The concept of the burden of a disease is an interesting one because it encompasses concepts beyond our traditional view of illness, i.e. pain and suffering. A disease, especially a chronic one like allergic rhinitis, has an impact on a sufferer through both the direct and indirect symptoms, complications (including health-related quality of life) and cost (direct, indirect and intangible costs...

Antibody deficiency diseases are common collectively. The clinical presentation of these disorders is extremely variable and they affect many different organ systems; hence these patients present to a variety of medical and surgical specialists. Patients suffering from antibody deficiency are susceptible to significant, recurrent infections and if diagnosis and implementation of therapy is dela...

Poorquality STI care has been well documented in this setting and has been the subject of some debate and policy responses. In the Department of Health’s HIV/AIDS and STD Strategic Plan for 2000 2005, the first ...
