Influence of adding titanium oxide (TiO2) nanoparticles on creep behavior, structure, mechanical and thermal properties of tin-antimony-lead and tin-aluminum-antimony bearing alloys have been studied and analyzed. Stress exponent of tin- antimony- lead and tin- aluminum- antimony- lead alloys decreased after adding titanium oxide. Elastic modulus of tin- antimony- lead increased after adding titanium oxide. Internal fiction of tin- antimony- lead and tin- aluminum- antimony- lead alloys varied after adding titanium oxide. Microstructure of tin- antimony- lead and tin- aluminum- antimony- lead alloys changed after adding titanium oxide. Strengths of tin- antimony- lead and tin- aluminum- antimony- lead alloys increased after adding titanium oxide. Thermal parameters of tin- antimony- lead and tin- aluminum- antimony- lead alloys varied after adding titanium oxide. The Sn79Sb15Pb5(TiO2)1 alloy has better bearing properties such as lowest internal friction, high elastic modulus and higher thermal diffusivity for industrial applications.
