Discussion Overview

The discussion revolves around determining the strength of individual phases within a microstructure, particularly in the context of phase diagrams and composite materials. Participants explore how to calculate the strength of each phase and its contribution to the overall strength of a composite material.

Discussion Character

  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant inquires about how to determine the strength of individual phases in a microstructure, referencing a formula for total strength that requires knowledge of the strengths of each phase.
  • Another participant explains that the formula mentioned is standard for evaluating properties of homogeneous composites and suggests that R1 and R2 correspond to the properties of pure phases found in compiled data tables.
  • A further inquiry is made about the existence of clear formulas for calculating strength based on individual phase properties, expressing a lack of familiarity with the referenced data tables.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the availability of clear formulas for calculating strength based on individual phases, and there is uncertainty regarding the existence and accessibility of relevant data tables.

Contextual Notes

The discussion highlights limitations in the availability of specific formulas and data, as well as the potential dependence on definitions of strength and phase properties.

Hello,

soon I will be taken examinations about microstructures and phase diagram.
Very interesting stuff, but I how can I determine the strenght of a phase in a microstructure?

I know the basic formula's to calculate the totale strenght, but I therefore I would need also the strenght of each individual phase.

For example: R=\frac{R_{1}.weight_{1}+R_{2}.weight_{2}}{weight total}
How can I get R1 and R2?

Anybody can help me?

Sorry for bumping if this is the case.

That's a standard formula for evaluating properties of homogeneous composites (i.e., the (volume/weight/molar) averaged values of a property given by parallel and series permutations of the properties of each phase generally bound the composite properties by assuming opposite extreme cases of load transfer).

The R1 and R2 values would just be associated with the pure phase properties, as found in compiled data tables.
 
So there doens't exist clear formulas for calculating strenght based on the properties of the individual phases?

Because I never heard of those tables, possible to give me a some background information about those data?

Anyone, need some more information.

Thansk anyway!
