On the resolidification behaviour of microsecond pulsed-laser-melted pool of bismuth

Surface modification of bismuth and tin under the action of a powerful ion beam of nanosecond duration

“…It has been established that particles of various shapes are formed on the metal surface due to an increase in the bismuth melt volume during crystallization. DOI: 10.1134/S1027451012030135 central part, in the form of a crystallized droplet with small dimensions, was formed in the melting region [2].However, surface relief formation during the homogeneous melting of a large bismuth or tin surface and its subsequent fast crystallization, typical for PIB action, has not been studied.…”

Specific features of high-power nanosecond ion beam action on polycrystalline bismuth

“…1). At the same time, investigation [2] of the local action of a microsecond pulsed laser beam on the surface a single crystalline bismuth sample showed that laser induced melting followed by crystallization led to the formation of a cone shaped central protru sion surrounded by a circular trough. Therefore, the surface relief formed during the crystallization of bis muth strongly depends on the conditions of melt solidification.…”
