20.500.12556/RUL-175488 Programska orodja za vrednotenje nekovinskih vključkov v jeklih magistrsko delo Program tools for the evaluation of non-metallic inclusions in steels master's thesis V magistrskem delu so bila izdelana in uporabljena programska orodja za vrednotenje nekovinskih vključkov v jeklih. Tri so bila izdelana v programskem okolju RStudio, eno pa v programskem okolju GNU Octave. Orodja so omogočala izdelavo združenih ternarnih diagramov v heksagonalni obliki, dvojen način prikaza točk (normalizacija z vsoto in neposredni masni delež), avtomatizirano kemijsko in morfološko klasifikacijo ter izdelavo ternarnih diagramov z več metodami filtriranja izstopajočih vrednosti. S tem je bila zagotovljena pregledna in ponovljiva analiza na dveh sklopih podatkov. Orodje za izdelavo ternarnih diagramov s prikazom dodatnih parametrov, filtriranja elementov, filtriranja opcijskih parametrov, statističnega filtriranja, filtriranja z Mahalanobisovo razdaljo in algoritmom »Isolation Forest« je omogočalo prikaz in poglobljeno analizo podatkov o nekovinskih vključkih. Sproten prikaz in posodobitve uporabljenih funkcij sta pospešila analizo, zmanjšala ročno delo in omogočila hitro prilagajanje uporabljenih parametrov. Orodja so bila preizkušena na sklopih podatkov za dve vrsti jekel. Izdelani so bili združeni ternarni diagrami; ternarni diagrami z dvojnim načinom prikaza točk; izvedena je bila klasifikacija vključkov, na podlagi katere so bili izdelani grafikoni; na ternarnih diagramih so bili prikazani nekovinski vključki z dodatnimi parametri in vrstami filtriranj ter njihovimi kombinacijami. Pri analizah nekovinskih vključkov predstavljena orodja zmanjšajo ročno delo, izboljšajo sledljivost rezultatov in potencialno omogočajo prenos analitičnega postopka v prakso. In the master's thesis, software tools for the evaluation of non-metallic inclusions in steels were developed and used. Three were developed in the RStudio programming environment, and one in the GNU Octave programming environment. The tools enabled the creation of combined ternary diagrams in hexagonal format, a dual display of points (normalization by sum and direct mass fraction), automated chemical and morphological classification, and the creation of ternary diagrams with several methods of filtering outliers. This ensured a transparent and repeatable analysis on two data sets. The tool for creating ternary diagrams with the display of additional parameters, element filtering, optional parameter filtering, statistical filtering, Mahalanobis distance filtering, and the "Isolation Forest" algorithm enabled the display and in-depth analysis of data on non-metallic inclusions. Real-time display and updates of the functions used accelerated the analysis, reduced manual work, and enabled rapid adjustment of the parameters used. The tools were tested on data sets for two types of steels. Combined ternary diagrams were created; ternary diagrams with a dual point display mode; inclusion classification was performed, on the basis of which charts were created; non-metallic inclusions were displayed on ternary diagrams with additional parameters and types of filtering and their combinations. In the analysis of non-metallic inclusions, the presented tools reduce manual work, improve the traceability of results and potentially enable the transfer of the analytical procedure into practice. nekovinski vključki vrednotenje klasifikacija programsko orodje ternarni diagrami non-metallic inclusions evaluation classification software tool ternary diagrams true false false V.
