Abstract

U ovome je radu određivana brzina ultrazvučnih valova na aditivno proizvedenim uzorcima izrađenim od alatnog čelika MS1 (X3NiCoMoTi18-9-5) s različitim debljinama slojeva gradnje. Prvi dio rada sastavljen je od opisa osnova mjerenja ultrazvukom i određivanja brzine ultrazvučnih valova. Opisani su utjecajni parametri na točnost mjerenja i pomoću dostupnih pisanih izvora dan je prikaz postojećih istraživanja mjerenja brzina transverzalnih i longitudinalnih valova te njihovi zaključci. U drugom dijelu rada provedena su mjerenja i statistička obrada brzina longitudinalnih i transverzalnih ultrazvučnih valova s obzirom na smjer ispitivanja i debljinu sloja gradnje uzoraka.

Abstract (english)

This paper determines the velocity of ultrasonic waves in additively manufactured tool steel
MS1 (X3NiCoMoTi18-9-5) samples with different build layer thicknesses. The first part of
the paper consists of a description of the basics of ultrasonic measurement and the
determination of ultrasonic wave velocity. Influential parameters affecting measurement
accuracy are described, and a review of existing research on the measurement of transverse
and longitudinal wave velocities is presented using available written sources, along with their
conclusions. In the second part of the paper, measurements and statistical analysis of
longitudinal and transverse ultrasonic wave velocities were conducted with respect to the
direction of testing and the build layer thickness of the samples.
