This process is also known as a tin pest and currently it causes problems mainly in the field of soldering materials. To avoid misrepresentation of the results of artificial ageing of the samples, we have decided to use historical materials for our
study. A sample from historical organ pipes was indented by naturally formed α-Sn polycrystalline particles by the load of 1 kg. The sample in the initial state was observed by SEM and analysed by EBSD mapping. The position of inoculator particles was documented again by SEM observation. Subseqently, the sample was freezed at -50 °C. The evolution of cracks started after 2.5h in the vicinity of indented α Sn particle. After 5 h of freezing, new cracks were observed also in the untouched parts of the sample. The crystallografical interconnectedness was not proven for polycrystalline samples.Workplace Institute of Physics of Materials Contact Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Year of Publishing 2025 Electronic address https://journalmt.com/artkey/mft-202401-0006_the-microscopic-study-of-the-evolution-of-the-phase-transformation-in-the-tin-after-the-indentation-of-an-inocu.php
