Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Transformation of retained austenite during tempering of high carbon steel
, 2003 Dilatometric, electron microscopic, and X-ray diffraction techniques have been employed to analyze transformations of the retained austenite in a 1.85 wt % C steel during tempering. The quenched steel contained 82% of retained austenite. Depending on the

Advanced Engineering Materials, EarlyView.A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application
Advanced Engineering Materials, EarlyView.N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Behavior of Retained Austenite on Spring Steel
Transactions of Japan Society of Spring Engineers, 1993 ばね鋼における残留オーステナイトの機械的, 熱的挙動を調査した。 従来ばねにおける残留オーステナイトは, 焼戻し過程で分解してしまうため特に注目されていなかったが, 耐へたり性向上のための高Si化及び高強度化のための焼戻し温度の低下により, 使用状態でも残留オーステナイトは残存しうる。残留オーステナイトは, 加工誘起変態によりマルテンサイト化することが知られているが, 本実験において衝撃破壊やショットピーニングにより変態が進行することが確かめられた。
