In this study the authors are exploring the profession of the military officer. The authors, which are military officers themselves, are doing this with an inductive quality based research method within a social science context. The military officer’s profession has during recent decades been under extensive changes both in organization and exercise within the military authorities of Sweden. Together with the political changes in the country of Sweden and the global changes regarding the strategic and security environment this has led to another view of the profession and its military context. These changes have led us to the need of explaining and the clarification of definitions, practice and concepts of the military officer. The investigation of the profession is conducted with an inside perspective. This study starts with interviews conducted together with personnel that in some way have a connection to the military profession. The interviews contain the core of the investigation, empirical data that tell us something about the profession of military officers, their on-the-job experiences and assumptions and conclusions regarding their own profession. Then follow an examination of doctrine and other literature regarding profession in a Swedish military context. This empirical data has led to a result presented as a model describing the military officer’s profession. The model itself is the first contribute of the study. The model has been used as an analytical instrument when investigating further empirical data. The interviews are divided into two different stages in the survey, the first part of interviews led to the model and the second part contains group interviews and this is where the actual analyses were completed. The main question of the study is whether the profession of military officers is coherent and congruent. The second contribute of this study is empirical findings that tell us a shift of focus is underway and has been for a while, within the profession, a "target-means displacement". This shifting of focus is explained using the practice of different logics, management logic and the logic of war. Management logic is defined mainly as bureaucracy and administration without an explicit connection to military knowledge and skills. The logic of war is defined as the opposite, knowledge and skills closely connected to the ability of leading, conducting and the organizing of combat at different tactical levels. Key words: Profession, military profession, officer’s military profession, management logic, the logic of war, bureaucracy, administration, focus shift, "target-means displacement.

Laser-material interaction of Nickel based superalloy Haynes 282 melt pools were studied for laser parameters similar to laser powder bed fusion (PBF-LB) without powder. The effect of power, speed, hatch distance and laser focus offset were analysed by characterizing different types of melt pool behaviour, including conduction, transition to keyhole, and keyhole mode. Focus offset parameter was found to modify the melting mode from keyhole to conduction type in experiments with and without powder. This change in melting mode is attributed to the variation in laser beam spot size for the same line energy. Such manipulation of type of melting with control of focus offset can be utilized as a method to optimize process parameters for novel materials in the PBF-LB process at high layer thickness. Based on the above study, cubes were built with refined process parameters utilizing powder layer thicknesses of 60- and 90-microns for improved productivity, using partial factorial design of experiment. The conduction mode of melting helped reducing defects, minimizing lack of fusion and keyhole porosity in specimens built with powder at 60- and 90-microns layer thickness. Effect of process parameters and indirect measure like area energy, on the melt pool overlap, defect level and dominant shape of the defects are presented. Optimizing the process parameters to identify the boundaries for building cubes with reduced porosity is also discussed. / Den Ni-baserade superlegeringen, Haynes 282, skannades med laserparametrar liknande de som används i laserpulverbäddfusion (PBF-LB), men utan pulver.Studien undersökte inverkan av effekt, hastighet, avstånd mellan två intilliggandeskanningspass och laserfokusförskjutning, vilket karakteriserades genom olikatyper av beteenden hos smältbadet, inklusive värmeledning, övergång frånvärmeledning till nyckelhål, och nyckelhål. Fokusförskjutningen visade sig ändrasmältbadets läge från nyckelhål till värmeledning. Denna förändring observeradesbåde i experiment utan pulver och i de med pulver. Förändringen beror påbreddningen av laserstrålens punktstorlek samtidigt som samma linjeenergibibehålls. Denna förändring i smältningstyp genom fokusförskjutning kananvändas som en metod för att optimera utforskningen av nya material i PBFLB-processen. Baserat på detta byggdes kuber med pulver med lagertjocklekar på 60 och 90mikrometer, användande olika processparametrar enligt en experimentell designbaserad på en central sammansatt design. Smältning genom värmeledning bidrogtill att minska defekter, minimera bindningsfel och nyckelhålsporositet i proversom byggts med pulver med lagertjocklekar på 60 och 90 mikrometer. Inverkanav processparametrarna och indirekta mått såsom areaenergi på smältbadetsöverlappning, defektnivå och den dominerande formen på defekter presenteras.Optimering av processparametrarna samt identifiering av parameterrymden föratt bygga kuber med minskad porositet undersöks också. / <p>Paper A is to be submitted, and paper C is acceptet and are not included in this licentiate thesis.
