INFLUENCE OF QUANTITATIVE ALLOYING OF TOOL STEELS FOR HOT DEFORMATION ON THE LEVEL OF HARDENING
The influence of complexly experimental tool steels: C (0,4–0,50%), Si (0,6–1,2%), Mn (0,17–0,8%), Cr (0,8–3%), W (0,9– 4%), Mo (0,01–3.5%) and V (0,28–1,8%) on their ability to hardening due to only high-temperature tempering after induction melting ...

ABSTRACT Objective To explore how cerebral hypoxia and Normal‐Appearing White Matter (NAWM) integrity affect MS lesion burden and clinical course. Methods Seventy‐nine MS patients, including 13 clinically isolated syndrome (CIS) patients and 66 relapsing–remitting multiple sclerosis (RRMS) patients, and 44 healthy controls (HCs) were recruited from ...
