Dr. Mehrangiz Rajabi and Dr. Elham Rajabi, a doctoral graduate of Amirkabir University of Technology, under the guidance of Dr. Kamran Dehghani, a member of the faculty of the university, launched a research project titled “Design and Construction of the New Alloy High TIZRNBMOV and Tizrnbmv”
Rajabi explained: Traditionally the Ti-6al-4V alloy is today considered the most common bone implaation, but there are always concerns about the abrasion and conceration of ions released by the body.
He emphasized: During the use of this traditional alloy, the release of toxic vanadium and aluminum ions around the tissue lead to diseases such as Alzheimer’s and neurological diseases, and said: In addition, the high amou of abrasion rates in artificial bonds can be another disadvaage of the traditional Ti-6al-4V alloy.
According to him; Due to the low abrasion resistance of the Ti-6al-4V alloy, wear-residual waste during service may also lead to tissue inflammation and other diseases.
“Given these constrais and problems of traditional alloys, rece new ahrop alloys, on the one hand, have been highly regarded because of their unique properties and because of their high biocompatibility as a replaceme for common biomedics,” he said.
He noted: In this study, two new alloys of Tizrnbmov and Tizrnbmota were designed and manufactured using thermodynamic relationships and the use of simulation software to produce materials. Their biomass properties were then compared to the traditional Ti-6al-4V alloy. The results of tests on the new TI35NB25ZR15MO15MO15V10 showed that this alloys showed much higher corrosion resistance in differe environmes, especially in the simulator environme than the conveional Ti-6al impla. Also, the examination of cellular reproduction and life showed that the high TIZRNBMOV and Tizrnbmota alloys show a much higher biomass and have a very good replaceme with the common Ti-6al-4V biomass.
Rajabi said another importa parameter in the examination of metal plaing properties is the elastic alloy modulus, which should not have a very high number of bones and coinued: In general, the elastic modulus of orthopedic alloys is about 1 to 2 GPa. The high -term elastic modulus of the conveional alloys in the long run results in the effect of stress shields, resulting in impact and osteoporosis loosening. However, the elastic modulus of the new ahrop alloy is designed to be less than traditional plaing and about 1-5 GB, indicating the high biomass of the new ahrop alloy.
He also added that the alloys’ abrasion behavior also showed that the alloy of Tizrnbmota’s eropy alloys showed a resistance of about 2 perce higher than the Ti-6al-4V. Therefore, the new designed alloy can be a very good alternative to the Ti-6al-4V alloy in medical engineering applications.
According to the researcher, high eropy alloys are a new group of alloys that, given their special properties, can be used for a wide range of applications, especially in medical engineering. The high eropy alloy we designed is aimed at using as a bone impla in medical engineering.
He added: “In general, the design and processing of the new TI35 NB25 ZR15MO15 V10 and Ti35 NB25 ZR15MO15 TA10 for medical and high -life use, which has not been studied so far, is one of the most importa innovations of this project.”
