Perryman [29] found that recovery at high temperatures, approaching recrystallization temperatures formed structural changes much similar to those observed at the lower temperatures:
In addition, it also provides deformation energy storage for the aging process, which causes the precipitation of the secondary phase and influences the recrystallization temperature of the alloy.
4b), which exceeds the recrystallization temperature which was verified by microstructural analysis.
The contents of both {111}<121> texture and {111}<110> texture are increased when the intermediate annealing temperature is raised from 800[degrees]C to 860[degrees]C in the condition of the primary recrystallization temperature of 820[degrees]C as shown in Figure 5(a).
The melting temperature ([T.sub.m]), melting enthalpy ([DELTA][H.sub.m]), cold crystallization temperature ([T.sub.ee]), cold crystallization enthalpy ([DELTA][H.sub.ee]), melt recrystallization temperature ([T.sub.mc] ), melt recrystallization enthalpy (Mime) and the degree of crystallinity ([X.sub.e]) were obtained from the thermograms.
ES extrusion is a hot working process; the magnesium alloy may be heated over the recrystallization temperature. ES extrusions are done on horizontal hydraulic presses which range from 100 to 11,000 metric tons.
The midpoint of the heat capacity change was chosen to represent the glass transition temperature ([T.sub.g]), the melting temperature ([T.sub.m]) refers to the endothermic peak, and the recrystallization temperature ([T.sub.c])can be observed from the exothermic peak.
There is an exotherm near 277 [degrees] C in an unannealed sample, which corresponds to a recrystallization temperature ([T.sub.c]).
The heat affected zone (HAZ) can be predicted by plotting all the points whose maximum temperature reaches more than recrystallization temperature 973 K but less than melting point temperature (1683 K) [4].
Instead of a step change at the melt front between the skin and core, a continuous change in modulus from the recrystallization temperature of [approximately] 120 [degrees] C to room temperature (23 [degrees] C) must be considered for UHMWPE.
For the alloys [alpha] after plastic strain, the important factor is also the exposure time of the base material to temperatures higher than the recrystallization temperature. The best plastic properties of welds were obtained when applying the average and high cooling rates at which the intensity of the grain growth is smaller.
