Abstract
Investigation of Temperature Effects on Microstructure of Pure Titanium
Highlights
Titanium is the most widely used implant of recent years, because of its protective effect on between bond and tissue during implantation, triggering the formation of calcium ions around it and accelerating bone formation [1]
It is seen that α-Ti structures are transformed to β-Ti structures with increasing sintering temperature
It is seen that pore diameters and grain size values decrease as sintering temperature increases
Summary
Titanium is the most widely used implant of recent years, because of its protective effect on between bond and tissue during implantation, triggering the formation of calcium ions around it and accelerating bone formation [1]. Titanium experiences an allotropic α-phase to β-phase transformation at a temperature of 882oC, which causes the most important mechanical properties of the metal to be changed, the flexibility. When the metal descends to room temperature, all of the weak β-phase structures can be transformed into α-phase structures. It is very important to discover a temperature and homogeneous microstructure in titanium metal and a temperature value in which the elevated B phase region coexists. In this case, it has been found suitable for the same metal types to increase the small sintering temperature by starting the experiment at the temperature value where allotropic conversion starts. In order to produce pure titanium metals, powder metallurgy has been the chosen method for the production, considering its success in producing metals with high melting temperatures
