Investigation of radiation shielding properties of B4C reinforced titanium composite metarials

The energy emitted by the nucleus during the transition of elements that are stable or unstable in nature from unstable to stable is called radiation. Radiation is something we are exposed to in our lives. However, when radiation exposure is excessive, it has fatal consequences for human health. Therefore, radiation absorption and radiation absorption materials have become very important in order to be protected from the effects of radiation. B4C compound has a very hard and neutron absorbing (radiation absorbing) feature that is used in many areas such as bulletproof vests and tank armor. However, due to the brittle nature of the B4C compound, it is not possible to use it alone. Therefore, titanium can be added into the matrix material in different proportions to turn it into a composite material and produce parts. In this thesis study, B4C reinforcement element and titanium matrix material were used in different ratios (100% Ti, 95%Ti+5% B4C, 90%Ti+10% B4C, 85%Ti+15% B4C, 80%Ti+20% B4C, 70%Ti+30% B4C and 60%Ti+%. 40 B4C) were brought together and produced as a composite material by the powder metallurgy method. Radiation absorption properties of the produced parts were determined depending on the component ratios and the B4C ratio, which changed. In the thesis study, the data obtained from the experimental results were compared with the theoretical data determined by the calculation method using the NIST XCOM program. When looked at for all samples in the study, it was concluded that as the B4C in the sample increases, the attenuation coefficients also increase.
