Material microstructure affected machining: a review

Manufacturing Review, 2017
The machining induced material microstructure evolution path is determined from the temperature and mechanical loading history. Inversely, the machining forces and machined part surface integrity are dependent on the material microstructure attributes ...

Predicting the Microstructure of a Valve Head during the Hot Forging of Steel 21-4N

Metals, 2018
Valve microstructure is important during hot forging. Austenitic 21-4N steel is often used in exhaust valves. In this study, the microstructure evolution of the forging valve process was predicted using the internal state variables (i.e., average grain ...

Microstructure evolution of HP40-Nb alloys during aging under air at 1000 °C [PDF]

, 2009
Two as-cast HP 40 alloys provided by different manufacturers were aged at 1000 °C under laboratory air. They had the same as-cast microstructure consisting of austenite dendrites delineated by a network of eutectic Nb-rich MC and Cr-rich M7C3 carbides ...

Microscopic seepage simulation of gas and water in shale pores and slits based on VOF

Open Physics
The microscopic pore-fracture structure and wettability have a significant influence on the two-phase seepage of shale gas and water. Due to the limitation of experimental conditions, the seepage patterns of gas and water in shale pores and slits under ...
