On Sunday, August 30, 2026, the Department of physics at the Faculty of science at the University of Mosul discussed the doctoral dissertation tagged ” manufacturing titanium–nickel bioalloys by powder technology and studying some of their mechanical and physical properties”, which was submitted by doctoral student Shaima Talal Atallah. The thesis was aimed at manufacturing and characterizing titanium–nickel (TiNi) alloys of various weight compositions, using powder metallurgy technology, by mixing and pressing powders, then subjecting the samples to various heat treatments and studying their effect on the microstructure and physical and mechanical properties of the alloy. The study included the use of XRD, SEM and Weds techniques to characterize the structure and composition, as well as the study of physical and mechanical properties, including periodic Thermal oxidation, hardness and compression resistance. The results showed that the increase in nickel content and heat treatment contributed to improving the microstructure and mechanical and physical properties of the alloys, as the hardness of Vickers before heat treatment increased from 118.9 to 244.9 HV, reaching after the first heat treatment to 338.56–438.81 HV, while compression resistance reached 445.8 MPa at a nickel content of 0.7 g. The oxidation results also showed an improvement in corrosion resistance and oxide layer growth, confirming the possibility of developing alloys with outstanding performance for Biological and engineering applications. The discussion Committee was chaired by Prof. Dr. Yahya Abdul Karim Salman, with the membership of Prof. Dr. Saleh Younis Darwish, assistant professor Hazem Saleh Ahmed, assistant professor Dr. Abdul Khaliq Ayoub Suleiman, assistant professor Dr. Iyad giad Jarjis, under the supervision and membership of Prof. Dr. Mahmoud Ahmed Hammoud and Prof. Dr. Mazen Ahmed Abdel Ghazal. At the end of the discussion, the head of the physics department, assistant professor Dr. Samir Ahmed Mahmoud, on behalf of the dean of the Faculty of Science, Dr. Hiam Adel Ibrahim, presented a letter of thanks and appreciation to Professor Saleh Yunus Darwish from the Faculty of science/Tikrit University, in appreciation of his participation in the discussion Committee and his trouble traveling. We wish our dear student continued success and success.
