ScholarBank@NUS Repository. https://doi.org/10.1016/j.intermet.2009.06.016 | Abstract: | The critical cooling rate and microstructure evolution were experimentally studied at cooling rates between 0.85 and 15.34 K/s by a Bridgman technique in Vit-1 (Zr41.2Ti13.8Cu12.5Ni10Be22.5). Our results show that the sample solidified at the rate above 10.03 K/s was fully amorphous whereas the samples solidified between 1.70 and 10.03 K/s were partially amorphous with crystalline phases, and samples solidified below 1.70 K/s were essentially crystalline. As the cooling rate decreased from 15.34 K/s to 1.82 K/s, the values of Tg and Tx were around 628 K and 702 K, respectively, but the heat of crystallization (ΔHx) decreased with decreasing cooling rate. © 2009. | Source Title: | Intermetallics | URI: | http://scholarbank.nus.edu.sg/handle/10635/86780 | ISSN: | 09669795 | DOI: | 10.1016/j.intermet.2009.06.016 |
