SUMMARY
Chromium and vanadium, when deposited in ultra-high vacuum (UHV) conditions, primarily undergo melting rather than sublimation. Both metals transition from solid to liquid before vaporization occurs. While sublimation may be observed in specific scenarios, such as metal multilayer formation on a target, it is not the primary phase change for these materials. Understanding these properties is crucial for accurately determining the volume needed for crucible filling during deposition processes.
