What are the differences between a congruent and incongruent phase transformation?
A congruent phase transformation occurs when a single phase changes into another single phase with the same composition. An incongruent phase transformation happens when a single phase changes into multiple phases with different compositions.
What is the significance of the pearlite phase in the isothermal transformation diagram?
The pearlite phase in the isothermal transformation diagram is significant because it represents a mixture of ferrite and cementite, which gives steel its strength and hardness. This phase plays a crucial role in determining the mechanical properties of the steel during the cooling process.
What is the transformation of a physical state of a substance into a different physical state?
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
Difference between eutectic and pereutectic points?
> A eutectic transformation, in which a two component single phase liquid is cooled and transforms into two solid phases.> A peritectic transformation, in which a two component single phase solid is heated and transforms into a solid phase and a liquid phase.
What do you call the transformation of a liquid to a gas?
The transformation of a liquid to a gas is called evaporation. This occurs when the molecules in a liquid gain enough energy to escape into the air as gas.
What are the differences between a congruent and incongruent phase transformation?
A congruent phase transformation occurs when a single phase changes into another single phase with the same composition. An incongruent phase transformation happens when a single phase changes into multiple phases with different compositions.
What are congruent melting alloys?
It is the phase transformation whereby there is no change in compisition.
Which of the following transformation will always produce a congruent figure?
The identity transformation.
What is the transformation in which the preimage and it image are congruent?
The transformation in which the preimage and its image are congruent is called a rigid transformation or isometry. This type of transformation preserves distances and angles, meaning that the shape and size of the figure remain unchanged. Common examples include translations, rotations, and reflections. As a result, the original figure and its transformed version are congruent.
Difference between line transformation ratio and transformation phase ratio?
line transformation ratio would be the turns ratio (ie voltage ratio), while the phase transformation ratio is most probably the phase shift introduced by a 3 phase transformer.
What is the transformation that reduces or enlarges a figure?
congruent figure
What is a congruence transformation A.Shrinking B.Rotating C.Stretching?
Rotation is congruent.
What is true about the result of a rigid transformation?
The object and its image are congruent.
Which transformation does not produce a congruent image?
A transformation that does not produce a congruent image is a dilation. While dilations change the size of a figure, they maintain the shape, meaning the resulting image is similar but not congruent to the original. In contrast, transformations such as translations, rotations, and reflections preserve both size and shape, resulting in congruent images.
When a transformation of a slide a flip or a turn is performed is the resulting image congruent or similar to the original?
Congruent in all three cases.
What type of transformation are the pre-image and the image congruent figures?
isometry
What transformation is not an isometry?
Dilation - the image created is not congruent to the pre-image
