Effect of cooling rate and alloying on the

Metallurgical Transactions, 1973
The pearlitic hardenability of a high-purity Fe-0.8 pct C alloy and zone-refined iron binary alloys containing Mn, Ni, Si, Mo, or Co was studied by means of hot-stage microscopy. The binary alloys were carburized in a gradient furnace to produce eutectoid compositions, thus eliminating proeutectoid phases.

Cryopreservation: Vitrification and Controlled Rate Cooling

2017
Cryopreservation is the application of low temperatures to preserve the structural and functional integrity of cells and tissues. Conventional cooling protocols allow ice to form and solute concentrations to rise during the cryopreservation process. The damage caused by the rise in solute concentration can be mitigated by the use of compounds known as ...

Cooling rates of seven hexahedrites

Geochimica et Cosmochimica Acta, 1978
Abstract Cooling rates for seven hexahedrites, (Uwet, Coahuila, Walker County, Lombard, Quillagua, Hex River Mountains and Tocopilla) have been determined using a ternary diffusion controlled phase growth analysis developed by the authors. The model is applied to the exsolution and growth of plate phosphides in the kamacite phase of hexahedrites ...

Rate of runaway evaporative cooling

Physical Review A, 2011
Evaporative cooling is a process that is essential in creating Bose-Einstein condensates in dilute atomic gasses. This process has often been simulated based on a model using a truncated Boltzmann distribution. This model assumes that the energy distribution up to the threshold energy can still be described by a Boltzmann distribution: it assumes ...

The influence of quenchant composition on the cooling rate

Journal of heat treatment and materials, 2009
Adequate selection of quenching media decreases the risk of tensile stresses, and also of cracking and workpiece distortion. High-performance quenching oils must have very high oxidation and thermal resistance and low sludge formation, must be non-staining and have a high flash point and acceptable heat-transfer characteristics.

On the rates of emplacement, crystallization and cooling

1993
We know very little with certainty about the times required to melt, segregate, crystallize and cool granitic magmas. Calculation is bedevilled by imponderables such as the effect of crustal depth, tectonic environment and mode of emplacement, and the extent to which fresh draughts of magma thermally recharge the system. It is extremely unlikely that a
