The influence of the vanadium content on the toughness and hardness of wear resistant high-alloyed Cr-Mo steel [PDF]

FME Transactions, 2017
Characteristics of air hardening steel are high hardness and low impact toughness. In order to increase the impact toughness while retaining high hardness value, studies were performed.

Research on Influential Mechanism of HAZ Impact Toughness for Shipbuilding Steel with Mg Addition

Metals, 2018
The welding performance of shipbuilding steel under large heat input could be improved greatly by the addition of Mg to the steel, but the impact toughness of the heat affect zone (HAZ) is not stable.

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Analysis of impact properties of cemented carbide by electromagnetic coupled cryogenic treatment

AIP Advances
Cemented carbide is often used as the pick-tip material for conical picks. The pick-tip often experiences premature failure due to insufficient toughness. This paper aims to improve the impact toughness of cemented carbide through electromagnetic coupled
