Impact of targeted chemistries on maraging steel precipitation evolution observed using SANS and APT [PDF]

, 2018
Building on a previous study of the novel aerospace maraging steel known as F1E, SANS and atom probe tomography (APT) have been used to study three variant chemistries designed to impact the growth and development of either laves or β-phase precipitates.

Evidence of austenite memory in PH 15-5 and assessment of its formation mechanism

Materials & Design, 2019
Austenite memory and subsequent spontaneous recrystallization during austenitization is stated for some types of soft martensitic stainless steels such as X4CrNiMo16-5-1 or 13Cr5Ni but have not been proposed for the commercial alloy PH15-5 until now ...

In-situ observation of liquid zinc-induced erosion behavior diffusion mechanism in zinc-coated 22MnB5 steel

Journal of Materials Research and Technology, 2020
In this study, the erosion of liquid zinc penetrating 22MnB5 steel during austenitization was investigated by an in situ method. High-temperature confocal laser scanning microscopy (HT-CLSM) results show that erosion occurred in several areas after ...

Influence of Austempering Temperatures on the Microstructure and Mechanical Properties of Austempered Ductile Cast Iron

Metals, 2021
The influence of the austempering temperatures on the microstructure and mechanical properties of austempered ductile cast iron (ADI) was investigated. ADI is nodular graphite cast iron, which owing to higher strength and elongation, exceeds mechanical ...

Effect of slab charging temperature on reverse transformation behavior and induced crack sensitivity through experiments and micromechanical analysis

Materials & Design, 2020
The relationship between the popular hot charging associated surface crack sensitivity and the charging temperature was studied from the view of phase transformation. The austenite reversion with various charging temperatures was investigated through the
