Detection of microstructural changes in metastable aisi 347, hss z-m4 and tool steel ferrotitanit wfn by mechanical loss coefficient at ultrasonic frequencies

HIGHLIGHTS

• who: Moritz Liesegang and colleagues from the Institute of Materials Science and Engineering, Technische Universitu00e4t Kaiserslautern, Kaiserslautern, Germany have published the research work: Detection of Microstructural Changes in Metastable AISI 347, HSS Z-M4 and Tool Steel Ferrotitanit WFN by Mechanical Loss Coefficient at Ultrasonic Frequencies, in the Journal: Materials 2022, 15, 6002. of 30/08/2022
• what: In the experiments carried out here, a chirp was used with the parameters given in Table 6. Despite the large percentual change of the loss coefficients, the change of elastic moduli seem to be the main reason . . .
