Phase transformation phases

Phase Transformation The change of matter from one state (solid, liquid, gas) to another is called phase transformation. Phase transformation occurs at definite temperature (m.p. b.p sublimation temp., etc.). [Pg.13]

Conversion of concentration from weight percent to mass per unit volume (kg/m ) is possible using Equation 4.9. Another driving force is responsible for phase transformations. Phase transformations are topics of discussion in... [Pg.144]

It is noted in Sections XVII-10 and 11 that phase transformations may occur, especially in the case of simple gases on uniform surfaces. Such transformations show up in q plots, as illustrated in Fig. XVU-22 for Kr adsorbed on a graphitized carbon black. The two plots are obtained from data just below and just above the limit of stability of a solid phase that is in registry with the graphite lattice [131]. [Pg.650]

This class of smart materials is the mechanical equivalent of electrostrictive and magnetostrictive materials. Elastorestrictive materials exhibit high hysteresis between strain and stress (14,15). This hysteresis can be caused by motion of ferroelastic domain walls. This behavior is more compHcated and complex near a martensitic phase transformation. At this transformation, both crystal stmctural changes iaduced by mechanical stress and by domain wall motion occur. Martensitic shape memory alloys have broad, diffuse phase transformations and coexisting high and low temperature phases. The domain wall movements disappear with fully transformation to the high temperature austentic (paraelastic) phase. [Pg.252]

Crack Reflection. Crack deflection can result when particles transform ahead of a propagating crack. The crack can be deflected by the locali2ed residual stress field which develops as a result of phase transformation. The force is effectively reduced on the deflected portion of the propagating crack resulting in toughening of the part. [Pg.324]

In engineering appHcations, the transport processes involving heat and mass transfer usually occur in process equipment involving vapor—gas mixtures where the vapor undergoes a phase transformation, such as condensation to or evaporation from a Hquid phase. In the simplest case, the Hquid phase is pure, consisting of the vapor component alone. [Pg.96]

Aging. When a gel is maintained in its pore Hquid, the stmcture and properties continue to change long after the gel point. This process is called aging. Four aging mechanisms can occur, singly or simultaneously polycondensation, syneresis, coarsening, and phase transformation (9,21). [Pg.252]

Eor the ferrite grades, it is necessary to have at least 12% chromium and only very small amounts of elements that stabilize austenite. Eor these materials, the stmcture is bcc from room temperature to the melting point. Some elements, such as Mo, Nb, Ti, and Al, which encourage the bcc stmcture, may also be in these steels. Because there are no phase transformations to refine the stmcture, brittieness from large grains is a drawback in these steels. They find considerable use in stmctures at high temperatures where the loads are small. [Pg.397]
