Microstructure Refining and Strengthening of Martensitic Steel

2009
The improvement of delayed fracture (DF) and fatigue resistance for steels, especially the former of martensitic steel, through microstructure refining and strengthening are the main concern in this chapter. Firstly, the effects of microstructure refinement in toughening and improving DF property of martensitic steels are studied. Secondly, methods for

Effect of La on Microstructure and Grain-Refining Performance of Al-Ti-C Grain Refiner

Journal of Rare Earths, 2006
Abstract Al-Ti-C grain refiner was prepared by SHS (self-propagating high-temperature synthesis)-melting technique. The effect of La on the microstructures of grain refiner was studied by OM, TEM, SEM, XRD, and EDS. The experimental results indicate that La can improve the wettability between liquid aluminum and graphite; the addition of La results ...

Evaluation of Microstructure and Refining Effect of Al–TiB2 and Al–5Ti–1B Grain Refiners

2019
High-concentration Al–Ti–B master alloy was prepared by melt self-propagating high-temperature synthesis, and then the extruder bar of intermediate alloy was also prepared. The grain refiner can be divided into two categories. One is TiB2 particles only, and the other is two particulate matter containing both TiB2 and TiAl3.

Microstructure Refinement and mechanical properties improvement of EUROFER97 steel

2022
EUROFER97 steel for nuclear fusion applications are usually manufactured by hot rolling and subsequent heat treatments: austenitization at 980 °C for 30 minutes, rapid cooling and tempering at 760 °C for 90 minutes. The aim of this work is to refine the microstructure of traditional EUROFER97 steel by means of a thermo-mechanical treatment, in order to
