A generalized hybrid modeling is proposed to estimate the chemical shrinkage and modulus evolutions at arbitrary temperatures. Using the existing curing kinetics modeling, a theoretical formulation is developed to provide a mathematical relationship between the evolution properties at arbitrary temperatures and those obtained at a reference temperature. The evolution properties at the reference temperature...
Differential scanning calorimetry (DSC) was used to study the formation of MgB2 from amorphous boron powder and MgH2/Mg powder. The B and powder mixture demonstrated that forms near 600degC with an estimated activation energy of 239 kJ/mole. The B and Mg powder mixture has an additional low temperature reaction near 425degC that is initiated by Mg(OH)2 decomposition. Similar effects can be duplicated...
