TL;DR: In this paper, a 2.9% C-22% Cr white cast iron was processed by spray forming aiming to investigate the resulting microstructure and the wear resistance of this alloy.
Abstract: A 2.9% C–22% Cr white cast iron was processed by spray forming (SF) aiming to investigate the resulting microstructure and the wear resistance of this alloy. Two gas to metal flow rate ratios (GMR) of 0.12 and 0.23 were used. The samples were characterized by wear resistance tests, X-ray diffraction (XRD), optical microscopy and scanning electron microscopy (SEM), in both as-sprayed condition and after heat treatments. The as-sprayed microstructure showed M7C3 carbides embedded in a matrix of austenite and martensite and after heat treatments the matrix became a mixture of pearlite and austenite, which presented a better performance in dry sand/rubber wheel wear resistance tests, particularly when associated with a fine distribution of carbides at the higher GMR.

TL;DR: In this article, the precipitation of copper within abnormal ferrite and pearlitic phases in hyper-eutectoid Fe-C-Cu and Fe-c-Mn-Cu experimental steels has been examined, principally by transmission electron microscopy, in terms of morphology, mechanism and crystallography.

TL;DR: In this article, an on-heating dilation conversional model was used to determine phase fraction based on measured volume changes during the formation of austenite in ferrite-pearlite hypoeutectoid steels.
Abstract: Dilatometry is often used to study solid-state phase transformations. While most steel transformation studies focus on the decomposition of austenite, this article presents an on-heating dilation conversional model to determine phase fraction based on measured volume changes during the formation of austenite in ferrite-pearlite hypoeutectoid steels. The effect of alloying elements on the transformation strain is incorporated into the model. Comparison of the conversional model predictions to measured transformation temperature (A c3) shows excellent agreement. The pearlite decomposition finish temperature (A pf ) predicted by the conversional model more closely matches experimental results when compared to standard lever rule calculations. Results show that including the effects of substitutional alloying elements (in addition to carbon) improves phase fraction predictions. The conversional model can be used to quantitatively predict intercritical austenite fraction with application to modeling, induction heating, intercritical annealing, and more complex heat treatments for hypoeutectoid steels.

Journal ArticleDOI
TL;DR: In this paper, atomic modeling is used to investigate the mechanical response and deformation mechanisms at 5'K temperature within the commonly reported orientation relationships between ferrite and cementite within pearlite: Bagaryatskii, Pitsch-Petch, Isaichev and their associated near orientations.
