Fe–Mn–Si-based shape memory alloys (Fe-SMAs) have attracted much research attention due to their potential applications for vibration mitigation, energy dissipation, and re-centering in the construction sector. Because of crucial impact precipitation on pseudoelasticity (PE) behavior Fe-SMAs, equilibrium phase diagram an Fe–17Mn–5Si–10Cr–4Ni–1(V-C) (wt%) SMA was used this study identify a low-t...

In this study, TC-PRISMA was employed to simulate the precipitation (number density and radius) of an FeMnSi-based shape memory alloy (FeMnSi-SMA), with a chemical composition Fe–17Mn–5Si–10Cr–4Ni-1(V, C) (wt%), during one-step two-step aging processes. addition, transmission electron microscopy (TEM) used study microstructures specimens, particularly VC precipitates, under several selected con...

We investigate the effects of annealing microstructure on low-cycle fatigue (LCF) life (Nf), cyclic stress behaviour and a Fe–15Mn–10Cr–8Ni–4Si alloy that exhibits deformation-induced transformation austenite (γ-phase) into ε-martensite (ε-phase). The rolled at 800°C was annealed 600°C, 700°C, 900°C to vary grain size, fraction recrystallised grains texture intensity. Fully reversed axial strai...

RATIONALE The present study evaluates the effect of pre-irradiation chemotherapy in pediatric patients with high risk medulloblastoma. Twenty-four (24) pediatric patients attended the pediatric unit of Kasr-El-Aini Center of Radiation Oncology and Nuclear Medicine (NEMROCK) from January 2000 to January 2003. PATIENTS AND METHODS Our patients were 13 boys and 11 girls aged 3-12 years with a me...
