“…New features of microstructures obtained with laser heat treatment of nickel-based alloys were discovered by Solov'ev et al in 1995 [6]. Authors processed materials with pulsed and continuous laser beam and after the process they observed same uniformly dispersed phases in dendritic structure as their predecessors have been recognizing since 1970s.…”

“…In that period researchers mainly investigated new microstructures obtained after laser processing along with their compositions due to the fact that they were hard to achieve using other methods. This trend continued but over time it became important to study properties of produced nickel-based structures and some publications from times between 1990 and 2000 contain results from microhardness measurements [4], thermal stability tests [5], crack formation analysis [6] or intergranular stress corrosion cracking behavior [7,8]. In recent years laser heat treatment of nickel-based alloys has been investigated in terms of specific analysis on influence of processing conditions on microstructure and thus on final properties [9].…”

In this paper researches which focus on laser heat treatment of nickel-based alloys are reviewed. Studies published from 1970s until today are taken into consideration. Publications which focus on influence of laser thermal processing on surface layer condition both on solid materials and pre-deposited coatings are described. Laser technologies in which additional materials are delivered during the process are not considered. In order to focus on studies investigating microstructural changes resulting mainly from material remelting, laser shock processing is also disregarded.
