Abstract
U ovom završnom radu fokus je bio na izradi računalnog programa u programskom paketu „PYTHON“ i njegovoj primjeni u svrhu dobivanja raspodjele tvrdoće po okruglom poprečnom presjeku uzorka (za čelik ENCK45 – HRN1531). Nakon izrade programa izvršena je usporedba rezultata raspodjele tvrdoće po presjeku dobivenih analitičkim postupkom i primjenom razvijenog računalnog programa. Kako su inicijalno rezultati dosta odstupali izvršena je korekcija u aproksimaciji modela funkcija u računalnom programu (koje opisuju Jominy krivulje), nakon čega se dobilo dobro podudaranje analitičkih rješenja i rezultata dobivenih primjenom računala. Praktični dio pokusa izvršen je u laboratoriju u kojem se čelična šipka (EN CK45 – HRN Č1531) promjera 50 mm i dužine 100 mm podvrgnula tretmanu toplinske obrade klasičnog poboljšavanja. Po završetku toplinske obrade izmjerena je tvrdoća po presjeku, nakon čega je izvršena usporedba dobivenih rezultata s analitičkim rezultatima i rezultatima dobivenim primjenom razvijenog programa.
Abstract (english)
In this final exam focus was on the design of program using computer software „PYTHON" and its application for the purpose of obtaining the distribution of hardness per cross section of the sample (for steel ENCK45 - HRN1531). After completion of the program, a comparison of the result of the hardness distribution by cross section obtained by analytical procedure and application of the developed computer program was performed. As the initial results largely departed, a correction was made in the approximation of the functions model in the computer program (which describes the Jominy curves), after which good matching of the analytical solutions and the results obtained by using the computer was obtained. The practical part of the experiment was carried out in a laboratory in which the steel rod (EN CK45 - HRN Č1531) 50 mm diameter and 100 mm lenght undergoing a hardening and tempering. At the end of the heat treatment, the hardness was measured by cross section, after which a comparison of the obtained results with the analytical results and results obtained with the application of the developed program was performed.
