Into the quenching & partitioning of a 0.2C steel: An in-situ synchrotron study [PDF]
Materials Science and Engineering: A, 2019 Abstract Quenching and partitioning (Q&P) is an effective way for retaining austenite at room temperature. The actual mechanisms responsible for austenite stabilization are still under debate, since it is impossible to track carbon diffusion with the conventional metallographic tools.

Non Photochemical Quenching mechanism in higher plants and in the unicellular alga Chlamydomonas reinhardtii [PDF]
, 2010 Light is a necessary ecological factor for oxygenic photoautotrophic organisms. Plants and algae require light for life but it can sometimes become a limiting factor or even cause stress events.

Processing Variants in Medium-Mn Steels
Metals, 2019 This paper highlights some recent efforts to extend the use of medium-Mn steels for applications other than intercritically batch-annealed steels with exceptional ductility (and strengths in the range of about 1000 MPa).
