Abstract:

We describe here the mechanical property evolution and precipitation hardening behavior under different cooling conditions including ultrafast cooling (UFC) + air cooling process and accelerated cooling (ACC) + air cooling process in a Ti-Mo microalloyed medium carbon steel is described here. The results demonstrate that the cooling procedure after hot rolling has a significant influence on the mechanical properties of the microalloyed steel. The yield strength and tensile strength that were obtained by ultrafast cooling (UFC) + air cooling process were higher than those from accelerated cooli

The paper presents an analytical description of real-time thermal field arising in industrial welding of a pipe wall taking account of possible accelerated cooling of the seam after welding. Considered was the case when the surface opposite to the welding bath is cooled with a spray of air or air-water mixture under certain pressure. A concept of characteristic cooling time is introduced depending on heat exchange coefficient at the cooled surface of the pipe. Calculations were performed for various heat exchange coefficient values ranging from 1•10–3 (no cooling) to 6•104 W/(m2•K) (cooling wi

This study investigates the influence of cooling rates on the microstructure and phase transformations of the high-entropy alloy Cr16Mn16Fe16Co16Ni16P20. The alloy was synthesized via arc melting and subjected to three cooling conditions: slow cooling (52 K/s), accelerated cooling after a short electric arc pulse (3018 K/s), and rapid quenching (10⁵–10⁶ K/s) using the melt-spinning method. The microstructures were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Mössbauer spectroscopy.

The Muon Ionisation Cooling Experiment (MICE) has been commissioned to provide the first demonstration of ionisation cooling. MICE will aim to demonstrate that ionisation cooling can be used to reduce of the emittance of a beam of muons to meet the requirements of future particle physics experiments such as the Neutrino Factory, or Muon Collider. As of October 2016, commissioning of Step IV of MICE has been completed which provides an opportune time to make material physics studies on the absorber material. The cooling formula that MICE will use to measure the emittance reduction was reviewed.

Abstract:

Hyperthermia is a state of elevated core temperature that rises rapidly above 40°C, secondary to failure of thermoregulation. Hyperthermia has many causes, but it is the hallmark of three conditions—heatstroke, malignant hyperthermia, and neuroleptic malignant syndrome. The clinical and metabolic alterations of hyperthermia, if left untreated, can culminate in multiple organ system failure and death. High temperature causes direct cellular death and tissue damage. The extent of tissue injury is a function of the degree and duration of hyperthermia. Heat-induced ischaemia-reperfusion injury, an

Abstract:

Abstract Carbon steel line pipes for sour service are required to exhibit hardness levels less than 250 HV10. The hardness of the inner pipe surface is especially critical, since sulphide stress cracking (SSC) may initiate at hardened surfaces. In recent years, high profile failures in sour environments were attributed to the presence of identified hard zones on TMCP pipe inner surfaces, and located far from welds. To help define the SSC limits of such material it is critical to know how these areas form. Based on these considerations, the European Pipeline Research Group has launched at the e

Abstract High-efficiency cross-corrugated PVC film packing materials, first Introduced In the U.S. for new counterflow cooling tower products In the 1970’s, have In a number of Instances recently been used to Improve the thermal performance of older splash and flat-sheet-filled counterflow towers. These highly interfaced PVC packs In new tower and retrofit service have been applied In a variety of circumstances and conditions. In some locations raw waters have fouled packs. This fouling process can, if left unchecked, reverse performance gains from the tower upgrade and add substantially to co

Abstract:

Abstract Electronics cooling and environmental control systems are required in enclosed manned spaces such as the inside of spacecraft or submersibles. Because egress from such spaces may not be possible in a short time frame, coolant leaks must have minimum toxicity. For this reason, propylene glycol coolants are preferred over the traditional ethylene glycol coolants. Corrosion inhibitor formulations are well developed for ethylene glycol coolants, but there is concern that the inhibitor suite for propylene glycol systems may not be as mature. In particular, coolant systems with a mixture of

Abstract This presentation will compare and contrast several anti-corrosive tidal zone coatings developed under a Navy SBIR program. Requirements for the coating included no VOC’s, surface tolerance to chlorides and water, fast cure to avoid washout by tides and waves, and thick build properties. Various trials of the material on dock sheet pilings and cooling tower fallout zones will be illustrated as well as accelerated lab test data.

In recent years a number of important developments in steel making, rolling, and heat treatment have been applied to the production of plate for API Grades X65 through X80 line pipe. Based on industry interest in the performance of these steels in line pipe, a research task was to investigate the characteristics of representative examples of these new pipes. The objectives of this task are to provide independent measurements of pipe properties and to examine the metallurgical characteristics that may affect their performance in service.

Abstract:

Experimental work was done to evaluate the effects of welding on the hardness, tensile and toughness properties of the heat affected zone (HAZ) of a series of commercial high strength micro-alloyed linepipe steels, produced through controlled rolling and accelerated cooling (thermo-mechanical control process - TMCP). The test materials, representative of modern low carbon linepipe steels, were selected such as to cover a broad range of chemistries (alloy /micro-alloy designs) and mechanical properties (X 70 and X 80).

Literature search focused on contributing factors for the appearance of near surface hard zones in line pipe steels manufactured using TMCP plate has been developed. Additional literature search was conducted on the influence of near surface hard zones on sulfide stress cracking of line pipe steels manufactured using TMCP plate. It can be inferred from the collective research evaluated that the chemical composition, rolling temperatures, scale formation during hot rolling and the accelerated cooling process contribute to the likelihood of forming near surface hard zones in TMCP plates used for

Abstract:

The ability of the flowing contents to remove heat from the pipe wall causes welds made onto in-service pipelines to cool at an accelerated rate and makes these welds particularly susceptible to hydrogen cracking. Several approaches exist for qualifying procedures where the thermal conditions produced by the flowing pipeline contents are simulated, allowing the ability of a procedure to produce sound, crack-free welds to be demonstrated. This report documents the various methods that can be used, under a number of different conditions, for simulating the proper cooling effects that will be exp

Abstract:

Welds made onto in-service pipelines tend to cool at an accelerated rate as the result of the flowing content"s ability to remove heat from the pipe wall. These welds are therefore likely to have high heat-affected zone (HAZ) hardness values and to be susceptible to hydrogen cracking. The use of thermal analysis modeling allows welding parameters (i.e., required heat input levels) to be selected based on anticipated weld cooling rates. Both the Battelle model and the recently developed PRCI Thermal Analysis Model for Hot Tap Welding assume that the pipe material is the most susceptible materia

Since the mid-1980s, the international community has controlled refrigerants that may damage the ozone layer and cause climate change based on several international agreements. In particular, the Montreal Protocol contributed to not only solving the ozone layer depletion problem but also limiting global warming. Given that the global demand for cooling would triple by 2050 and this rise would increase global greenhouse gas emissions significantly, the Montreal Protocol has expanded its regulatory scope to decarbonize the cooling sector through the adoption of the Kigali Amendment.
