Mixed graphite cast iron for automotive exhaust component applications [PDF]

open access: yesChina Foundry, 2017
Both spheroidal graphite iron and compacted graphite iron are used in the automotive industry. A recently proposed mixed graphite iron exhibits a microstructure between the conventional spheroidal graphite iron and compacted graphite iron.

The Effect of Manganese on the Crystallisation Process, Microstructure and Selected Properties of Compacted Graphite iron [PDF]

open access: yesArchives of Metallurgy and Materials, 2019
The paper presents the effect of manganese on the crystallization process, microstructure and selected properties: cast iron hardness as well as ferrite and pearlite microhardness. The compacted graphite was obtained by Inmold technology.

Graphite creep negation during flash spark plasma sintering under temperatures close to 2000$^\circ$C [PDF]

open access: yesCarbon, Elsevier, 2020, 162, pp.106-113, 2020
Graphite creep has high importance for applications using high pressures (100 MPa) and temperatures close to 2000 {\textdegree}C. In particular, the new flash spark plasma sintering process (FSPS) is highly sensitive to graphite creep when applied to ultra-high temperature materials such as silicon carbide.

The Use of the XGBoost and Kriging Methods in the Prediction of the Microstructure of CGI Cast Iron [PDF]

open access: yesArchives of Foundry Engineering, 2023
Compacted Graphite Iron (CGI), is a unique casting material characterized by its graphite form and extensive matrix contact surface. This type of cast iron has a tendency towards direct ferritization and possesses a complex set of intriguing properties ...

GRB 180325A: dust grain-size distribution and interstellar iron nanoparticles contribution [PDF]

open access: yes, 2022
We modelled dust grain-size distributions for carbonaceous and silicates dust, as well as for free-flying iron nanoparticles in the environment of a $\gamma$-ray burst (GRB) afterglow, GRB 180325A. This GRB, at $z=2.2486$, has an unambiguous detection of the 2175 \r{A} extinction feature with $R_V=4.58$ and $A_V=1.58$.

Effect of microstructure and mechanical properties on cutting force of different cast irons with similar tensile strength [PDF]

open access: yesChina Foundry, 2019
Flake graphite iron, compacted graphite iron and spheroidal graphite iron with various tensile strengths were cast. They were selected and grouped according to roughly the same tensile strength, and then the main cutting force in each group was ...

Recycling End-of-life Polycarbonate in Steelmaking; $\textit{Ab Initio}$ Study of Carbon Dissolution in Molten Iron [PDF]

open access: yesInd. Eng. Chem. Res. 2014, 53, 10, 3861-3864, 2022
The scarcity of fossil fuels as carbon resources has motivated the steelmaking industry to search for new carbon sources such as end-of-life polymeric products. Using $\textit{ab initio}$ molecular dynamics simulation, we demonstrate that 41% of polycarbonate's carbon content is readily dissolved in molten iron's interface at $T$ = 1823 K which is ...
