Annealed state

Silver in the fully annealed state is a soft, ductile metal which is easily fabricated into the very wide range of forms employed in industry by the... 

Platinum work-hardens at approximately the same rate as palladium or copper, a 25% cold reduction in thickness raising the hardness from about 40 HV in the fully annealed state to 75 HV. Cast platinum is usually slightly harder than the same grade of metal in the wrought and annealed state. 

A 99.5% Cu—0.5% Te alloy has been on the market for many years (78). The most widely used is alloy No. CA145 (number given by Copper Development Association, New York), nominally containing 0.5% tellurium and 0.008% phosphorous. The electrical conductivity of this alloy, in the annealed state, is 90—98%, and the thermal conductivity 91.5—94.5% that of the tough-pitch grade of copper. The machinability rating, 80—90, compares with 100 for free-cutting brass and 20 for pure copper. 

The mechanical and physical properties of some alloys chosen for rebar in concrete are relevant in the performance of the alloys. The mechanical properties of some reinforcing bar alloys are given in Table 7.11. All the steels except duplex steels were subjected to cold work in order to increase their strength. Duplex S31803 steel in the annealed state exhibits strength levels close to the values of the cold-worked alloys. 

Fig. 6.31. Conductivity data for a p -p-p device. A is the annealed state, B is after a current has flowed for 24 hours, and P is after prolonged illumination. The reduction in space charge limited current is attributed to defect formation (Kruhler et at. 1984).

Glasses are isotropic in annealed state under the action of hydrostatic pressure. But they become anisotropic and exhibit birefringent behaviour when they are not properly annealed and when subjected to... 

The experiments on the variation of mechanical properties with cold work (thin series) and the cupping tests (both in the worked and annealed states) were carried out at the Chalais Meudon Laboratory. The experiments on the effect of annealing at different temperatures after cold work were carried out at the Conservatoire des Arts et Metiers. Reports of the latter experiments are given in the appendices. 

If S be the initial section of a bar in the annealed state and if s be the final section after cold work (drawing or rolling), the cold work may be defined in terms of the deformation as follows —... 

At 50 % cold work, the Shock Resistance reaches almost its minimum value. In the annealed state, the Shock Resistance varies between 8 and 8-5 kilogramme-metres per sq. cm., without any appreciable difference between test pieces cut longitudinally or transversely. This difference, however, becomes more marked as the cold work increases.

In Figure 24.10a and b the 01s emission spectrum of a 53 A Ca film on Si02 in its pristine and its annealed state is illustrated for comparison. The Ca deposition as well as the thermal treatment (/ = 1 h 7 = 180 °C) were conducted without breaking the UHV prior to and in between the respective XPS measurements. We find that an annealing of the Ca adsorbate results in a significant...

NOTE Shear strengths and therefore material multipliers will be greater for material hardnesses other than annealed as shown eibove. Higher multipliers will be required and should be adjusted projxrrtionately to the annealed state.
