Abstract Sixteen borate glass compositions comprising K 2 O and SrO were screened, using a design of mixtures approach, to model compositional effects on dissolution, CT imageability, MRI relaxivity (R ). Based the characteristics each network, together with dose determination toxicological risk, composition identified as BKSA16 was selected preferred for pre-clinical evaluations related genicu...

The effects of strain on the microstructure and mechanical properties 0.81C-0.22Si-0.31Mn (wt%) high-carbon steel were investigated by thermal simulation, scanning electron microscopy, high-resolution transmission microscopy (HRTEM), an backscatter diffractometer (EBSD). It was found that when deformed at 670 °C (a temperature between A1 Ar1), a deformation-induced pearlite transformation cemen...

The degree to which parameters affect the spheroidization heat treatment of steel was calculated by setting conditions Cr-Mo and using data analysis such as S/N ratio ANOVA. After analyzing transformation temperatures steel, Ac1 Ac3 , a DSC, were set accordingly. surface hardness measured for used an evaluation index. correlation analyzed comparing spheroidized volume fraction hardness, Pearson...

Abstract Railway wheels are commonly made from medium carbon steels (~0.55 wt.% C), heat treated to a near pearlitic microstructure with 5–10% pro-eutectoid ferrite. During the operation of freight trains, where block brakes used, high thermal loads occur together contact stresses, which combined can affect mechanical properties material. In this study, effects annealing on local and in railway...
