The special carburizing by vacuum carburizing furnace
Journal of Advanced Science, 2005 The carburizing process has been used as surface hardening technology for many years. Carburizing process has been widely used mainly in the machine industry, and has resulted by the end of today.Recently, the vacuum carburizing process has attracted attention not only as the conventional gas carburizing process but as a new carburizing method.The ...

Vacuum carburizing of a dual phase steel.
Transactions of the Iron and Steel Institute of Japan, 1985 A dual phase steel has been developed for which grain refining treatment subsequent to vacuum carburizing treatment at high temperature above 1000°C is not necessary. This 2wt% Si steel, which contains 0.3 wt% V and 0.04 wt% Nb, has a fine structure in both the core and case, sufficient surface hardness and excellent mechanical properties equivalent to

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects
Advanced Engineering Materials, EarlyView.This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.

Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
