Machinability of Experimental Ti-Cu Alloys

Abstract

This study is an investigation of the machinability of experimental Ti-Cu alloys (2, 5, and 10 mass% Cu) as new dental titanium alloy candidates for CAD/CAM use. The alloys were slotted with a vertical milling machine and carbide square end mills under two cutting conditions. Their machinability was evaluated through cutting force using a three-component force transducer fixed on the table of the milling machine. The horizontal cutting forces of the Ti-Cu alloys tended to increase as the concentration of copper increased. The feed force for Ti-10%Cu was more than twice as large as that for titanium under both cutting conditions. Alloying with copper reduced the machinability of titanium under the present cutting conditions. The adverse effect on the cutting force was attributed to the higher degree of tensile strength and hardness of the Ti-Cu alloys than of titanium.

Evaluation of the machinability of Ti–Sn alloys

“…In the present study, the cutting lengths (machinability) of the Ti-Sn alloys increased as the concentration of Sn increased. These results were similar to those found in other alloy systems by some researchers [12,13,31]. The magnitudes of cutting length for Ti-20Sn and Ti-30Sn were much higher than those for c.p.…”

“…Although many attempts have been made to explain and predict the machinability of a material by its strength or hardness, no general consensus has been reached regarding an explanation [12]. The hardness of the Ti-Sn alloys became higher than that of c.p.…”

“…Machinability is defined as the relative ease of machining a metal. Kikuchi et al [11][12][13] have examined the machinability of dental titanium alloys through the cutting force.…”

“…This study, therefore, examined the machinability or the relative ease of machining these dental alloys. Over the past years, only a few studies have evaluated the machinability of dental alloys with the objective of developing new materials for dental CAD/CAM applications [11][12][13][14]. Machinability is defined as the relative ease of machining a metal.…”

Evolution of the functional properties of titanium–silver thin films for biomedical applications: Influence of in-vacuum annealing

“…A particularly noticeable example comes from the field of implants or dental prostheses in dental practice, where the Ti-Ag system is being increasingly studied and tested [2,17]. The importance of this binary intermetallic-like compound comes from the fact that it can provide a multifunctional response by offering a set of proper A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT 5 chemical, electrical, thermal, and mechanical properties, together with excellent biocompatibility and good resistance to wear and corrosion [2,11,[18][19][20][21].…”
