diffusionless transformationsの例文

• When the edge cools fast a diffusionless transformation occurs, turning the austenite into very hard martensite.
• When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, but then harden as they age.
• This is called a " diffusionless transformation . " When the crystal matrix changes to its low temperature arrangement, the atoms of the solute become trapped within the lattice.
• The martensite forms during a diffusionless transformation, in which the transformation occurs due to shear-stresses created in the crystal lattices rather than by chemical changes that occur during precipitation.
• The transition between these two structures requires very little thermal activation energy because it is a diffusionless transformation, which results in the subtle but rapid rearrangement of atomic positions, and has been known to occur even at cryogenic temperatures.
• A "'diffusionless transformation "'is a phase change that occurs without the long-range diffusion of atoms but rather by some form of cooperative, homogeneous movement of many atoms that results in a change in crystal structure.
