Diagnostics of the Microstructural Changes in Sub-zero-processed Vanadis 6 P/M Ledeburitic Tool Steel

Original language description

Specimens made from P/M Vanadis 6 cold-work steel were austenitized, quenchced and tempered for various combinations of the parameters. The selected sets of samples, also in the sub-zero range, were treated at a temperature of -196°C after quenching. Themicrostructure was investigated as a function of the austenitizing temperature and the parameters of the sub-zero processing using transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM) and X-ray diffraction. It was found that the as-quenched microstructure is composed of martensite, retained austenite and carbides. The sub-zero processing reduced the amount of retained austenite and led to an increase in the tetragonality of the martensitic lattice. As a result, the hardness of material was higher by 2 HRc before the tempering of the samples after the sub-zero processing, but the hardness of the sub-zero-processed material after tempering is about 2,5 HRc lower than that of the non-sub-zero-p
