A Comparison Of Different Measurement Methods To Evaluate Strain-Induced Martensite Formation In A Metastable Austenitic Stainless Steel
Authors: K.S. Raghavan, G. Thomas, J. Arnold, A. Gill, and T. Gnaupel-Herold
Accurate measurement of phase volume fraction of ferrite, austenite and martensite is of considerable interest in the context of third generation advanced high strength steels that rely on the transformation induced plasticity (TRIP) mechanism in order to develop high strength, high ductility properties.

The effect of the coal powder granularity of different metamorphic degree coal on combustion characteristics was studied by thermo-gravimetric analyzer. The experimental results show that the smaller particle size of coal powder, the more obvious change of pulverized coal ignition temperature, burnout temperature, integrated combustion characteristics index and mean apparent activation energy, for high metamorphic degree coal. The smaller particle size contributes to the combustion of high metamorphic degree coal. With the decrease of coal particle size, the burnout temperature of low metamorphic degree coal increases.

Additions of Li to Mg alloys can transform the hcp to bcc, substantially increasing the ductility of the Mg-Li alloys and further reducing its density. Mg-Li alloys exhibit two phase structures between 5 and 10 wt% Lithium content consisting of a(hcp) Mg-rich and p(bcc) Li-rich phases. Mg- Li binary alloys containing greater than approximately 11 wt% Li form a single phase bcc microstructure (p phase).
