The Precipitation of Carbides during Tempering of High Carbon Martensite*

perature range between 260° and 360°C. Jack showed that thin platelets of cementite formed at the beginning of this stage(10). In high carbon steels, the transformation twin interfaces are potent nucleation sites for the cementite formation and the cementite is related to the ferrite by Bagaryatskii's orientation relationship(2)(3)(11). Although there is no direct evidence of its existence in s...

STRUCTURAL AND MAGNETIC PROPERTIES OF Co-Nd SUBSTITUTED ZnFe2O4 FERRITES SYNTHESIZED BY CO-PRECIPITATION TECHNIQUE

A series of Zn1-xCoxNdyFe2-yO4 spinel ferrites (x=0,0-0.5, y=0.00-0.10) was synthesized using the co-precipitation method sintered at 1000 o C. Synthesized Ferrites were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometery (VSM). The diffraction patterns show the formation of the spinel phase along with some traces of second phase Nd2O3...

Behaviors of Additives in Ferrites

The influence of various cations ranging from alkali metals to transition metals according to the periodic table were discussed. The ferrites used were Ni ferrite, Mg ferrite and Zn ferrite having different cation distributions in the spinel lattice. Cations having appropriate ionic radii and valencies are soluble in ferrite. Several additives formed other phase in addition to the spinel phase....

Analysis of Fatigue Crack Paths in Cold Drawn Pearlitic Steel

In this paper, a fracto-metallographic analysis was performed on the cracked specimens of cold drawn pearlitic steel subjected to fatigue tests. Fatigue cracks are transcollonial and exhibit a preference for fracturing pearlitic lamellae, with non-uniform crack opening displacement values, micro-discontinuities, branchings, bifurcations and frequent local deflections that create microstructural...

Understanding dual precipitation strengthening in ultra-high strength low carbon steel containing nano-sized copper precipitates and carbides

Low carbon ferritic steel alloyed with Ti, Mo and Cu was hot rolled and interrupt cooled to produce nano-sized precipitates of copper and (Ti,Mo)C carbides. The steel had a tensile strength of 840 MPa, an increase in yield strength of 380 MPa over that of the plain carbon steel and reasonable ductility. Transmission electron microscopy and small angle neutron scattering were used to characteriz...
