Biography
Dr. Timotius Pasang (Tim) has a BE degree in Metallurgical Engineering in Bandung, Indonesia, and a PhD in Materials Engineering from Monash University in Melbourne, Australia. In his professional career, he has spent five years at the Indonesian Aircraft Industry, and three years as Materials & Failure Analysis Consultant working for PSB Corp. in Singapore. Dr. Pasang is Deputy Head of the Mechanical & Manufacturing Department at AUT University, Auckland – New Zealand. Dr. Pasang and his family have been living in New Zealand since 2004. He was a Loewy Visiting Professor at the Materials Science and Engineering Department at Lehigh University.
Abstract
Titanium and its alloys have found many applications in many areas including aerospace and biomedical. Their excellent corrosion resistance and high strength-to-weight ratio are the main driver behind their applications in the aerospace industries. While Ti-6Al-4V (Ti64), an alpha-beta alloy, has always been the backbone and it counts up to 90% of the titanium alloys used in industries, unalloyed or commercially pure titanium and beta alloys are slowly gaining some respects. Recently, a new beta alloy, Ti-5Al-5V-5Mo-3Cr (Ti5553) was introduced and has been specified for some major applications in the Boeing 787 “Dreamliner”. Since this alloy is relatively new, areas for research is widely open. From the manufacturing point of view, its machinability and weldability are relatively unknown. Research is being conducted on (i) the phase transformation on the Ti5553 interface and wear resistance of the drills as a result of secondary machining operation, and (ii) weldability of Ti5553 alloy using an electron beam welder.
For biomedical applications, apart from corrosion and strength, titanium also offers excellent biocompatibility with human’s tissue. Orthopedic area has taken a full advantage of these properties for hip and knee replacements, and /or bone fracture fixation. Maxillofacial and orthodontics areas have also been benefited from the excellent properties offered by titanium. Current research on titanium dental implant is focused on (i) the effect of machined-threads vs. ground-threads on fatigue resistance, and (ii) stability and fatigue resistance of a specific design dental implant. Commercially pure titanium (CP Ti) is the material of interest in this research project.
This presentation highlights some of the on-going research projects in titanium at AUT University in collaboration with other universities such as Lehigh University and Akita University (Japan), and various industries. The current research projects including machining and machinability, electron beam welding, and implants particularly for dental applications.
