AISI H13 die steel specimens were subjected to heating at 1020 °C followed by oil quenching and double tempering 520 °C. Subsequently, these deep cryogenic treatment -185 in liquid nitrogen environment for 16 h then soft 100 once the attained room temperature. Thereafter, scanning electron microscopy (SEM) analysis backscatter diffraction (EBSD) analysis. The electrochemical corrosion activity was investigated 3.5% NaCl 23 ± 0.5 evaluating evolution of open circuit potential over time...
Cryogenic treatment could be useful in preventing AISI H13 steel forging dies from the premature failure that is continuously under action of mechanical stresses and temperature. This work involves heating specimens to 1020°C, quenching oil followed by double tempering at 520°C for 2 h subsequently undergoing cryogenic minus185°C cryosoaking periods starting 8 32 h. Dry sliding wear tests were performed room temperature on pin-on-disc testing machine 40 N load, 3 m s–1 speed 6000 distance....
The current experimental work investigated the engine performance and emissions when a compression ignition was powered by 1-propanol Electronic Mode (EM) fumigation with biodiesel diesel fuel. (20 %) blended reference (80 %). blend values were notified to compare different timings of EM fumigation. 1 ms, 3 5 ms injected fuel into inlet manifold varying loads. test mentioned mixture timing reported operating parameters. subjected additional brake power timings. Initially, experiments...
Influence of cryogenic treatment on AISI H13 hot work die steels has been studied to correlate carbide density with surface roughness and dry sliding wear. This includes hardening specimens at 1020°C, oil quenching followed by double tempering 500°C then −185°C for different cryosoaking periods from 8 32 h, soft 100°C. The wear behaviour pin-on-disc a load 40 N speed 3 m s −1 the distance 6000 m. A model proposed elaborate upon effect tertiary precipitation improvement roughness,...
Abstract A reduction in the size of electronic equipment increases heat generation rate. Failure occurs if is not dissipated properly. This paper examines performance aluminium two-phase closed thermosyphon for cooling equipment. Acetone charged was fabricated with an inside diameter 17.05 mm and 1 thickness. series experimentations were performed inclination angles 10°–90° at selected filling ratios 30, 60 100 %, along inputs 100, 200 300 W. The condenser section flow rate water maintained...
<div>AISI H13 hot work tool steel is commonly used for applications such as forging and extrusion in mechanical working operations that face thermal stress fluctuations, leading to premature failures. Cryogenic treatment was applied AISI improve the surface hardness thereby fatigue resistance. This involves failure analysis of specimens subjected cryogenic gas nitriding. The were heated 1020°C, oil quenched followed by double tempering at 550°C 2 h, subsequently, deep cryogenically...
<div>Transient temperature analysis is involved in the thermal simulation of heat treatment process, which hot metal changes with respect to time from an initial state final state. The critical part determine transfer coefficient (HTC) between and quenching medium or quenchant. In liquid quenching, water becomes complicated it difficult HTC. current experimentation a carbon steel EN 9 rod diameter 50 mm length 100 was quenched ethylene glycol mixture different concentrations.

<div class="section abstract"><div class="htmlview paragraph">The essential aspect of an automobile is its braking system. Brakes absorb the kinetic energy rotating parts, i.e., wheels, and dissipate this into surroundings in form heat. This entire process quite complex, brake disc subjected to extreme thermal structural stresses along with deformation, which might damage disc. paper presents a analysis Audi Q3 using ANSYS 2021-R1.
