Microstructure evolution of austenite-to-martensite transformation in low-alloy steel via thermodynamically assisted phase-field method

Journal of Materials Research and Technology
The austenite-to-martensite phase transformation plays a crucial part in the microstructure evolution of steel, with the morphology and grain size of martensite being key factors that influence the mechanical properties. This study explores the influence

Acoustic Activity of Intergranular Corrosion Sensitized AISI 304L in Double‐Loop Electrochemical Potentiodynamic Reactivation Test

Materials and Corrosion, EarlyView.
Intergranular corrosion of AISI 304L is analyzed, combining DLEPR test and AE. Slow scan rate polarization reveals time‐shifted and frequency‐dependent acoustic emission in the active region of the DLEPR curve, allowing a separation between passive oxide rupture, intergranular corrosion and pitting. ABSTRACT Intergranular corrosion (IGC) susceptibility

Effect of strain-induced martensite on the tribocorrosion of AISI 316L austenitic stainless steel in seawater

, 2017
Strain-induced phase transformation of austenite into martensite often results in the hardening and strengthening of metastable austenite stainless steel; thus, pin-on-disc friction experiments were carried out to investigate the effect of strain-induced

Improving the high stress abrasive wear resistance of medium carbon quenched and partitioned bainitic steel by controlling the phase transformation sequence

Journal of Materials Research and Technology
To address the high stress abrasive wear challenges in mining and metallurgical applications, the three microstructures of martensite-bainite-retained austenite, bainite-martensite-retained austenite and fully martensite were obtained by controlling the ...

Study the effects of residual B19' phase on the phase transformation in shape memory NiTi alloys fabricated by laser powder bed fusion

Journal of Materials Research and Technology
The shape memory effect of near-equiatomic Ni–Ti shape memory alloys (SMAs) fabricated via laser powder bed fusion (LPBF) is attributed to the diffusionless phase transformation between austenite (B2) and martensite (B19').
