Driving force for martensitic transformation inNi2Mn1+xSn1−x

Driving force for martensitic transformation in steels

recently determined LVl~ to be 111918 J mol-I at temperatures below 1000 K, and pointed out that their experimental data were free from various 'intercept effects' which had dogged earlier investigations. Similarly, for T<1000K, they deduced '\~s=51.44Jmol-IK-I. There seem to be no data on the variation of LVl~ or ,\~s as a function of x. However, Lobo and Geigerl found that LVll: and ,\S~S do ...

Driving Force for Nucleation of Multi-Component Gas Hydrate

Based on driving force for crystallization of one-component gas hydrate, in this report an expression for the supersaturation for crystallization of multicomponent gas hydrate is derived. Expressions for the supersaturation are obtained in isothermal and isobaric regimes. The results obtained are applied to the crystallization of hydrates of mixtures of methane plus ethane and can apply to ...

Complexion-mediated martensitic phase transformation in Titanium

The most efficient way to tune microstructures and mechanical properties of metallic alloys lies in designing and using athermal phase transformations. Examples are shape memory alloys and high strength steels, which together stand for 1,500 million tons annual production. In these materials, martensite formation and mechanical twinning are tuned via composition adjustment for realizing complex...
