Heat Treating Copper Beryllium - Materion

Heat treating the copper beryllium alloys is a two step pro- cess which consists of solution annealing and age hardening. Because Materion Brush Performance Alloys performs the required solution anneal on all wrought products prior to shipping, most fabricators' primary concern is the age hardening process. The following text details this process,

Recovery (metallurgy) - Wikipedia

Recovery is a process by which deformed grains can reduce their stored energy by the removal or rearrangement of defects in their crystal structure. These defects, primarily dislocations, are introduced by plastic deformation of the material and act to increase the yield strength of a material. Since recovery reduces the dislocation density the process is normally accompanied by a reduction in ...

We calculate the stress, using the stress formula: σ = F/A = 30*10³ / (1*10⁻⁴) = 300*10⁶ = 300 MPa. Finally, we divide the stress by strain to find the Young's modulus of steel: E = σ/ε = 300*10⁶ / 0.0015 = 200*10⁹ = 200 GPa.
