are converted into liquid hydrocarbons of various forms in the presence of iron and cobalt as catalysts. Sasobit forms a homo-geneous solution with the base binder upon stirring (1.5% of the binder, mass......
conditions, as well as the complex kinematics and dynamics of the parts. The widely adopted solution uses the least-squares technique to fit the friction coefficients. First, since the mixed friction......
with the aging treatment and this layer affected the mechanical properties of the material. SINGH et al [4] solution-treated the alloy under and over the β transition temperature and then applied aging... optical microscopy. To prepare samples for optical microscopy analysis, they were ground, polished, and finally etched with Kroll solution (consisting of 5% HF, 10% HNO3, and 85% distilled H2O, volume......
