The stability of metastable austenite grains in advanced high strength steels

, 2015
The transformation of the austenite to the martensite provides the transformation-induced plasticity (TRIP) effect which can contribute to the high work hardening rate and the good mechanical properties of 3rd advanced high strength steels (AHSS).

Lattice‐Defect‐Coordinated Microstructural Continuity and Mechanical Compatibility in LPBF‐Fabricated CoCrNi/316L Bimetallic Structures

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Bimetallic structures fabricated by laser powder bed fusion (LPBF) provide an effective strategy for achieving multifunctional integration, yet interfacial structural continuity and the role of lattice defects remain insufficiently understood.

Microstructure and cleavage in lath martensitic steels

Science and Technology of Advanced Materials, 2013
In this paper we discuss the microstructure of lath martensitic steels and the mechanisms by which it controls cleavage fracture. The specific experimental example is a 9Ni (9 wt% Ni) steel annealed to have a large prior austenite grain size, then ...

Formation of Austenite Grains and Grain Boundary Segregation in Heating Process of Steel [PDF]

, 1993
application/pdfThe transforming process was traced on 1%Cr-0.5%Mo steel in the conditions of as-hot-rolled, quenched-and-tempered. The rapid heating process was employed from the viewpoint of weld thermal cycle. In as-hot-rolled specimen, austenite grain

Effect of Ausforming Temperatures on Bainitic Transformation During Isothermal Quenching of 42CrMo Steel

Metals
The influence of ausforming temperature on the isothermal bainitic transformation behavior of 42CrMo steel was systematically investigated using thermo-mechanical simulation, dilatometric analysis, and electron backscatter diffraction (EBSD). The results

Effect of silicon and prior deformation of austenite on isothermal transformation in low carbon steels

, 2009
Isothermal transformation (TTT) behavior of the low carbon steels with two Si contents (0.50 wt pct and 1.35 wt pct) was investigated with and without the prior deformation.

A new strategy for highly wear-resistant ball using carbon nanotube composites: Study on the impact wear resistance and interfacial bonding mechanism

Journal of Materials Research and Technology
Traditional low-alloy wear-resistant steel balls have a complex and costly manufacturing process, resulting in poor wear resistance. Fortunately, carbon nanotubes offer a promising solution due to their elastic modulus, lightweight nature and good wear ...

Revealing Prior Austenite Grain Boundaries of 4340 Steel [PDF]

, 2014
Grain growth during austenitization has a negative effect on fatigue strength. Several methods have been investigated in order to determine an accurate method of measuring the austenite grain size of 4340 steel.
