If the part cools to an eject-able temperature in 30 sec, then the cooling rate for the material is 680[degrees] F (378[degrees] C)/min
On the other hand, the dynamic thermal conditions such as cooling rate (non-isothermal cooling and heating treatment) is important factor in determining the crystallization, morphology and final properties of iPP [54-57] inversely, the study of dynamic crystallization and melting behavior can also provide detailed information about the crystallization kinetics of the crystallization process [58], which is of great help in the design of morphology and properties of the polymer and in understanding the nature of the crystallization behavior.
The composition has excellent cooling performance, cooling rate distribution is reasonable, it can enable the parts to obtain sufficient hardness and hardening depth, but also to control the deformation hardening; excellent high temperature oxidation performance, long-term and stable quality of quenching; Bright good; in addition to the workpiece before the next step after quenching rust played a role in the short-term.
This increase in cooling rate reduces crystalline ice formation within and around small samples such as those found in X-ray crystallography and in oocyte and embryo vitrification.
Because the temperature inside the metal drops rapidly in a very short period of time, uneven cooling rate at different locations could result in high temperature gradients at some locations in the part.
In a hot stamping process, a fast cooling rate of the steel during forming and quenching in the cold dies is critical to obtain the ultrahigh strength and geometrical accuracy of the formed part.
the associated cooling rates, were designed to enable a particular limit cooling rate to be identified: the one at which no bainite forms in the material within the critical cooling interval of 950/300[degrees]C.
The process variables that must be controlled to achieve the as-cast ausferritic microstructure include the chemical composition of the metal and the cooling rate of the different sections of the casting.
For the definition of cryoconservation protocols becomes necessary to know several factors: sperm characteristics of the species, extender composition, sperm:extender ratio, cryoprotectant and dosage, cooling rate and thawing, equilibrium time and fertilization tests.
Heating or cooling rate affected the melting behavior of PLLA, the low-temperature and high-temperature melting peak shifted to low temperature with increasing of rate, and the ratio of melting peak area between low-temperature melting peak and high-temperature melting peak decreased.
Compared to the air system, the radiant system cooling rate, representing the hourly sensible cooling load, reaches a higher peak value for both the floor TABS (85% higher) and ceiling TABS (49% higher).
The energy exchange can also be profiled to allow a variable cooling rate within a cycle.
