School of Metallurgical and Ecological Engineering... composition, phase assemblage, andistribution. Furthermore, the formation mechanism of the protective layer was determined after clarifying the source of each componenFinally, a technical strategy......
Formation mechanism of the graphite-rich protective layer in blast furnace hearthsKe-xin Jiao1,2,Jian-liang Zhang1,2,Zheng-jian Liu1,2,Feng Liu1,2,Li-sheng Liang31. School of Metallurgical... and investigated damage in blast furnace hearths to estimate the formation mechanism of the protective layer. The results illustrate that a significant amount of graphite phase was trapped within the hearth......
and attached particles present Al3Sc/Al3Zr1-xScx core-shell structure. The formation mechanism of the structure was systematically investigated by a mathematical model. Key words: Al-Sc-Zr master alloy; morphology; core-shell structure; cooling rate; formation mechanism 1 Introduction Optimizing the properties of alloy detailedly requires realizing not only the precipitation kinetics of its......
and formation mechanism were analyzed by SEM. The result shows that, with the increase of temperature, the yield strength and tensile strength of CP titanium TA1 decrease from the original values of 83.7..., and the ductility increases, resulting in the quasi-cleavage fracture as the major failure mechanism. Key words: commercially pure titanium; high-temperature tensile; fracture morphology; formation......
