Abstract: Abstract Herein, a premature failure analysis of structural tempered high-strength boron steel 27MnCrB5–2 bolts (0.0006 wt B), used for railcar wheel-axle assembly, is presented. Fractographic analysis revealed a moderate ductile fracture. The applied torque produced elongation… read more here.

DOI: 10.3390/ma14061556
Abstract: High boron steel is prone to brittle failure due to the boride distributed in it with net-like or fishbone morphology, which limit its applications. The Quenching and Partitioning (Q&P) heat treatment is a promising process… read more here.
