Advanced Engineering Materials, EarlyView.Feasibility of improving the mechanical and shape‐memory properties of a CoCrFeMn high‐entropy alloy through carbon addition is investigated. The recovery strain of the carbon‐containing alloy is approximately four to five times higher than that of the carbon‐free alloy.

The Influence of Austenite Grain Size on the Mechanical Properties of Low-Alloy Steel with Boron
, 2017 This study forms part of the current research on modern steel groups with higher resistance to abrasive wear. In order to reduce the intensity of wear processes, and also to minimize their impact, the immediate priority seems to be a search for a ...

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling
Advanced Engineering Materials, EarlyView.Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

Simulating the Effects of Substrate Pre-Heating on the Final Structure of Steel Parts Built by Laser Powder Deposition [PDF]
, 2004 Tool steel parts built by laser powder deposition often present a heterogeneous distribution of properties caused by the complex structural transformations that occur during the deposition process.

Advanced Functional Materials, EarlyView.It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

Crystallization of gray cast irons
Литьë и металлургияCrystallization of gray cast irons is a nanostructured process in which nanocrystals of iron, silicon and graphite play a major role. Austenite microcrystals are not solid solutions of silicon and carbon atoms in the γ‑Fe crystal lattice.

Graphite and Solid Fraction Evolutions during Solidification of Nodular Cast Irons
Metals, 2015 Ductile iron casting production is strongly affected by austenite and graphite distribution obtained after the solidification process. At the same time it is accepted that solidification behavior can be considered as hypo-, hyper- or eutectic depending ...
