Analysis of Turning Performance on AISI O1 Steel Using VO+nMoS2 as Coolant

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
AISI O1 cold work steel is a hard‐to‐machine material as a reason of its good temperature resistance, superficial hardness, and lesser response to wear. Hence, material removal from such hard materials is both cost‐ and time‐consuming. Conventional cutting fluids fail to lessen the hotness at the tool‐work junction.

Utilization of moderate pressure and elevated temperatures in the optimization of Ti2AlC‐cBN composites using SPS technique

International Journal of Ceramic Engineering &Science, Volume 3, Issue 2, Page 60-76, March 2021., 2021
The formation reaction mechanism of Ti2AlC‐cubic‐boron‐nitride (cBN) composite materials was investigated using different particle sizes at different volume percentages of cBN (20 and 40 vol%), at a constant moderate pressure while varying time and temperature. The results show that, under the investigated conditions, Ti2AlC decomposed at 1300°C with a
