Effect of surface modification on mechanical properties and thermal stability of Sm–Co high temperature magnetic materials

ABSTRACTThe thermal stability of polymethylmethacrylate loaded with silica nnaoparticles is investigated. The temperature dependence of the mass has been accurately fitted with a single Boltzmann-like dependence. The effect of surface functionalization, size of silica nanoparticles, and concentration of silica nanoparticles is analyzed. A weak increase of the thermal stability of polymethylmethacrylate has been obtained by loading the polymer matrix with nanoparticles. Surface functionalization produced a modest increase in the thermal stability (compared to composites with silica nanoparticles without surface modification).

General Method

There has been a number of works trying to improve thermal stability of PVC as it is one of the most widely used plastics for various applications. The incorporation of heat stabilizer is a general method to stabilize PVC. However, its thermal stability could also be improved by blending with polyethylene. Organoclay, montmorillonite (MMT) in particular, has been found to improve thermal stability of polymers due to its high temperature resistance. This research is aimed to use organic modified MMT (OMMT) to improve thermal property of PVC. It was found from the research that organic grafted MMT (O-g-MMT) could improve thermal stability of PVC better than OMMT. The mechanical properties of O-g-MMT/PVC and OMMT/PVC of the blends were also reported

Thermal Stability Of

Ordered-alpha titanium alloys having a DO19 type structure have good potential for high temperature (600°C) applications, due to the thermal stability of the ordered phase and the inherent resistance to recrystallization of these alloys. Five different Ti-Al-Ga alloys consisting of equal atomic percents of aluminum and gallium solute additions up to the stoichiometric composition, Ti3(Al, Ga), were used to study the growth kinetics of the ordered phase and the nature of its interface.The alloys were homogenized in the beta region in a vacuum of about 5×10-7 torr, furnace cooled; reheated in air to 50°C below the alpha transus for hot working. The alloys were subsequently acid cleaned, annealed in vacuo, and cold rolled to about. 050 inch prior to additional homogenization
